  // Note to a Fellow Implementor:
  // Ahh, accessing a child node at an index. Seems like it should be so simple,
  // doesn't it? Unfortunately, this particular method has caused us a surprising
  // amount of pain. As you'll note below, this method has been modified to walk
  // the linked list of child nodes rather than access the child by index
  // directly, even though there are two (2) APIs in the DOM that do this for us.
  // If you're thinking to yourself, "What an oversight! What an opportunity to
  // optimize this code!" then to you I say: stop! For I have a tale to tell.
  //
  // First, this code must be compatible with simple-dom for rendering on the
  // server where there is no real DOM. Previously, we accessed a child node
  // directly via `element.childNodes[index]`. While we *could* in theory do a
  // full-fidelity simulation of a live `childNodes` array, this is slow,
  // complicated and error-prone.
  //
  // "No problem," we thought, "we'll just use the similar
  // `childNodes.item(index)` API." Then, we could just implement our own `item`
  // method in simple-dom and walk the child node linked list there, allowing
  // us to retain the performance advantages of the (surely optimized) `item()`
  // API in the browser.
  //
  // Unfortunately, an enterprising soul named Samy Alzahrani discovered that in
  // IE8, accessing an item out-of-bounds via `item()` causes an exception where
  // other browsers return null. This necessitated a... check of
  // `childNodes.length`, bringing us back around to having to support a
  // full-fidelity `childNodes` array!
  //
  // Worst of all, Kris Selden investigated how browsers are actualy implemented
  // and discovered that they're all linked lists under the hood anyway. Accessing
  // `childNodes` requires them to allocate a new live collection backed by that
  // linked list, which is itself a rather expensive operation. Our assumed
  // optimization had backfired! That is the danger of magical thinking about
  // the performance of native implementations.
  //
  // And this, my friends, is why the following implementation just walks the
  // linked list, as surprised as that may make you. Please ensure you understand
  // the above before changing this and submitting a PR.

  /**
    An instance of `Ember.Application` is the starting point for every Ember
    application. It helps to instantiate, initialize and coordinate the many
    objects that make up your app.
  
    Each Ember app has one and only one `Ember.Application` object. In fact, the
    very first thing you should do in your application is create the instance:
  
    ```javascript
    window.App = Ember.Application.create();
    ```
  
    Typically, the application object is the only global variable. All other
    classes in your app should be properties on the `Ember.Application` instance,
    which highlights its first role: a global namespace.
  
    For example, if you define a view class, it might look like this:
  
    ```javascript
    App.MyView = Ember.View.extend();
    ```
  
    By default, calling `Ember.Application.create()` will automatically initialize
    your application by calling the `Ember.Application.initialize()` method. If
    you need to delay initialization, you can call your app's `deferReadiness()`
    method. When you are ready for your app to be initialized, call its
    `advanceReadiness()` method.
  
    You can define a `ready` method on the `Ember.Application` instance, which
    will be run by Ember when the application is initialized.
  
    Because `Ember.Application` inherits from `Ember.Namespace`, any classes
    you create will have useful string representations when calling `toString()`.
    See the `Ember.Namespace` documentation for more information.
  
    While you can think of your `Ember.Application` as a container that holds the
    other classes in your application, there are several other responsibilities
    going on under-the-hood that you may want to understand.
  
    ### Event Delegation
  
    Ember uses a technique called _event delegation_. This allows the framework
    to set up a global, shared event listener instead of requiring each view to
    do it manually. For example, instead of each view registering its own
    `mousedown` listener on its associated element, Ember sets up a `mousedown`
    listener on the `body`.
  
    If a `mousedown` event occurs, Ember will look at the target of the event and
    start walking up the DOM node tree, finding corresponding views and invoking
    their `mouseDown` method as it goes.
  
    `Ember.Application` has a number of default events that it listens for, as
    well as a mapping from lowercase events to camel-cased view method names. For
    example, the `keypress` event causes the `keyPress` method on the view to be
    called, the `dblclick` event causes `doubleClick` to be called, and so on.
  
    If there is a bubbling browser event that Ember does not listen for by
    default, you can specify custom events and their corresponding view method
    names by setting the application's `customEvents` property:
  
    ```javascript
    var App = Ember.Application.create({
      customEvents: {
        // add support for the paste event
        paste: 'paste'
      }
    });
    ```
  
    By default, the application sets up these event listeners on the document
    body. However, in cases where you are embedding an Ember application inside
    an existing page, you may want it to set up the listeners on an element
    inside the body.
  
    For example, if only events inside a DOM element with the ID of `ember-app`
    should be delegated, set your application's `rootElement` property:
  
    ```javascript
    var App = Ember.Application.create({
      rootElement: '#ember-app'
    });
    ```
  
    The `rootElement` can be either a DOM element or a jQuery-compatible selector
    string. Note that *views appended to the DOM outside the root element will
    not receive events.* If you specify a custom root element, make sure you only
    append views inside it!
  
    To learn more about the advantages of event delegation and the Ember view
    layer, and a list of the event listeners that are setup by default, visit the
    [Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation).
  
    ### Initializers
  
    Libraries on top of Ember can add initializers, like so:
  
    ```javascript
    Ember.Application.initializer({
      name: 'api-adapter',
  
      initialize: function(container, application) {
        application.register('api-adapter:main', ApiAdapter);
      }
    });
    ```
  
    Initializers provide an opportunity to access the container, which
    organizes the different components of an Ember application. Additionally
    they provide a chance to access the instantiated application. Beyond
    being used for libraries, initializers are also a great way to organize
    dependency injection or setup in your own application.
  
    ### Routing
  
    In addition to creating your application's router, `Ember.Application` is
    also responsible for telling the router when to start routing. Transitions
    between routes can be logged with the `LOG_TRANSITIONS` flag, and more
    detailed intra-transition logging can be logged with
    the `LOG_TRANSITIONS_INTERNAL` flag:
  
    ```javascript
    var App = Ember.Application.create({
      LOG_TRANSITIONS: true, // basic logging of successful transitions
      LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
    });
    ```
  
    By default, the router will begin trying to translate the current URL into
    application state once the browser emits the `DOMContentReady` event. If you
    need to defer routing, you can call the application's `deferReadiness()`
    method. Once routing can begin, call the `advanceReadiness()` method.
  
    If there is any setup required before routing begins, you can implement a
    `ready()` method on your app that will be invoked immediately before routing
    begins.

    /**
      Registers a factory that can be used for dependency injection (with
      `App.inject`) or for service lookup. Each factory is registered with
      a full name including two parts: `type:name`.
       A simple example:
       ```javascript
      var App = Ember.Application.create();
       App.Orange = Ember.Object.extend();
      App.register('fruit:favorite', App.Orange);
      ```
       Ember will resolve factories from the `App` namespace automatically.
      For example `App.CarsController` will be discovered and returned if
      an application requests `controller:cars`.
       An example of registering a controller with a non-standard name:
       ```javascript
      var App = Ember.Application.create();
      var Session = Ember.Controller.extend();
       App.register('controller:session', Session);
       // The Session controller can now be treated like a normal controller,
      // despite its non-standard name.
      App.ApplicationController = Ember.Controller.extend({
        needs: ['session']
      });
      ```
       Registered factories are **instantiated** by having `create`
      called on them. Additionally they are **singletons**, each time
      they are looked up they return the same instance.
       Some examples modifying that default behavior:
       ```javascript
      var App = Ember.Application.create();
       App.Person = Ember.Object.extend();
      App.Orange = Ember.Object.extend();
      App.Email = Ember.Object.extend();
      App.session = Ember.Object.create();
       App.register('model:user', App.Person, { singleton: false });
      App.register('fruit:favorite', App.Orange);
      App.register('communication:main', App.Email, { singleton: false });
      App.register('session', App.session, { instantiate: false });
      ```
       @method register
      @param  fullName {String} type:name (e.g., 'model:user')
      @param  factory {Function} (e.g., App.Person)
      @param  options {Object} (optional) disable instantiation or singleton usage
      @public
    **/

      var _registry;

      (_registry = this.registry).register.apply(_registry, arguments);
    },

    /**
      Define a dependency injection onto a specific factory or all factories
      of a type.
       When Ember instantiates a controller, view, or other framework component
      it can attach a dependency to that component. This is often used to
      provide services to a set of framework components.
       An example of providing a session object to all controllers:
       ```javascript
      var App = Ember.Application.create();
      var Session = Ember.Object.extend({ isAuthenticated: false });
       // A factory must be registered before it can be injected
      App.register('session:main', Session);
       // Inject 'session:main' onto all factories of the type 'controller'
      // with the name 'session'
      App.inject('controller', 'session', 'session:main');
       App.IndexController = Ember.Controller.extend({
        isLoggedIn: Ember.computed.alias('session.isAuthenticated')
      });
      ```
       Injections can also be performed on specific factories.
       ```javascript
      App.inject(<full_name or type>, <property name>, <full_name>)
      App.inject('route', 'source', 'source:main')
      App.inject('route:application', 'email', 'model:email')
      ```
       It is important to note that injections can only be performed on
      classes that are instantiated by Ember itself. Instantiating a class
      directly (via `create` or `new`) bypasses the dependency injection
      system.
       **Note:** Ember-Data instantiates its models in a unique manner, and consequently
      injections onto models (or all models) will not work as expected. Injections
      on models can be enabled by setting `Ember.MODEL_FACTORY_INJECTIONS`
      to `true`.
       @method inject
      @param  factoryNameOrType {String}

       1. Deactivate existing routes
      2. Destroy all objects in the container
      3. Create a new application container
      4. Re-route to the existing url
       Typical Example:
       ```javascript
      var App;
       run(function() {
        App = Ember.Application.create();
      });
       module('acceptance test', {

       test('first test', function() {

      });
       test('second test', function() {
        // App is again freshly reset
      });
      ```
       Advanced Example:
       Occasionally you may want to prevent the app from initializing during
      setup. This could enable extra configuration, or enable asserting prior
      to the app becoming ready.
       ```javascript
      var App;
       run(function() {
        App = Ember.Application.create();

       module('acceptance test', {
        setup: function() {
          run(function() {
            App.reset();
            App.deferReadiness();

      Initializer receives an object which has the following attributes:
      `name`, `before`, `after`, `initialize`. The only required attribute is
      `initialize`, all others are optional.
       * `name` allows you to specify under which name the initializer is registered.
      This must be a unique name, as trying to register two initializers with the
      same name will result in an error.
       ```javascript
      Ember.Application.initializer({
        name: 'namedInitializer',
         initialize: function(container, application) {
          Ember.debug('Running namedInitializer!');
        }
      });
      ```
       * `before` and `after` are used to ensure that this initializer is ran prior
      or after the one identified by the value. This value can be a single string
      or an array of strings, referencing the `name` of other initializers.
       An example of ordering initializers, we create an initializer named `first`:
       ```javascript
      Ember.Application.initializer({
        name: 'first',
         initialize: function(container, application) {
          Ember.debug('First initializer!');
        }
      });
       // DEBUG: First initializer!
      ```
       We add another initializer named `second`, specifying that it should run
      after the initializer named `first`:
       ```javascript
      Ember.Application.initializer({
        name: 'second',
        after: 'first',
         initialize: function(container, application) {
          Ember.debug('Second initializer!');
        }
      });
       // DEBUG: First initializer!
      // DEBUG: Second initializer!
      ```
       Afterwards we add a further initializer named `pre`, this time specifying
      that it should run before the initializer named `first`:
       ```javascript
      Ember.Application.initializer({
        name: 'pre',
        before: 'first',
         initialize: function(container, application) {
          Ember.debug('Pre initializer!');
        }
      });
       // DEBUG: Pre initializer!
      // DEBUG: First initializer!
      // DEBUG: Second initializer!
      ```
       Finally we add an initializer named `post`, specifying it should run after
      both the `first` and the `second` initializers:
       ```javascript
      Ember.Application.initializer({
        name: 'post',
        after: ['first', 'second'],
         initialize: function(container, application) {
          Ember.debug('Post initializer!');
        }
      });
       // DEBUG: Pre initializer!
      // DEBUG: First initializer!
      // DEBUG: Second initializer!
      // DEBUG: Post initializer!
      ```
       * `initialize` is a callback function that receives two arguments, `container`
      and `application` on which you can operate.
       Example of using `container` to preload data into the store:
       ```javascript
      Ember.Application.initializer({
        name: 'preload-data',
         initialize: function(container, application) {
          var store = container.lookup('store:main');
           store.pushPayload(preloadedData);
        }
      });
      ```
       Example of using `application` to register an adapter:
       ```javascript
      Ember.Application.initializer({
        name: 'api-adapter',
         initialize: function(container, application) {
          application.register('api-adapter:main', ApiAdapter);
        }
      });

  /**
    The DefaultResolver defines the default lookup rules to resolve
    container lookups before consulting the container for registered
    items:
  
    * templates are looked up on `Ember.TEMPLATES`
    * other names are looked up on the application after converting
      the name. For example, `controller:post` looks up
      `App.PostController` by default.
    * there are some nuances (see examples below)
  
    ### How Resolving Works
  
    The container calls this object's `resolve` method with the
    `fullName` argument.
  
    It first parses the fullName into an object using `parseName`.
  
    Then it checks for the presence of a type-specific instance
    method of the form `resolve[Type]` and calls it if it exists.
    For example if it was resolving 'template:post', it would call
    the `resolveTemplate` method.
  
    Its last resort is to call the `resolveOther` method.
  
    The methods of this object are designed to be easy to override
    in a subclass. For example, you could enhance how a template
    is resolved like so:
  
    ```javascript
    App = Ember.Application.create({
      Resolver: Ember.DefaultResolver.extend({
        resolveTemplate: function(parsedName) {
          var resolvedTemplate = this._super(parsedName);
          if (resolvedTemplate) { return resolvedTemplate; }
          return Ember.TEMPLATES['not_found'];
        }
      })
    });
    ```
  
    Some examples of how names are resolved:
  
    ```
    'template:post'           //=> Ember.TEMPLATES['post']
    'template:posts/byline'   //=> Ember.TEMPLATES['posts/byline']
    'template:posts.byline'   //=> Ember.TEMPLATES['posts/byline']
    'template:blogPost'       //=> Ember.TEMPLATES['blogPost']
                              //   OR
                              //   Ember.TEMPLATES['blog_post']
    'controller:post'         //=> App.PostController
    'controller:posts.index'  //=> App.PostsIndexController
    'controller:blog/post'    //=> Blog.PostController
    'controller:basic'        //=> Ember.Controller
    'route:post'              //=> App.PostRoute
    'route:posts.index'       //=> App.PostsIndexRoute
    'route:blog/post'         //=> Blog.PostRoute
    'route:basic'             //=> Ember.Route
    'view:post'               //=> App.PostView
    'view:posts.index'        //=> App.PostsIndexView
    'view:blog/post'          //=> Blog.PostView
    'view:basic'              //=> Ember.View
    'foo:post'                //=> App.PostFoo
    'model:post'              //=> App.Post

    The `DataAdapter` helps a data persistence library
    interface with tools that debug Ember such
    as the [Ember Extension](https://github.com/tildeio/ember-extension)
    for Chrome and Firefox.
  
    This class will be extended by a persistence library
    which will override some of the methods with
    library-specific code.
  
    The methods likely to be overridden are:
  
    * `getFilters`
    * `detect`
    * `columnsForType`
    * `getRecords`
    * `getRecordColumnValues`
    * `getRecordKeywords`
    * `getRecordFilterValues`
    * `getRecordColor`
    * `observeRecord`
  
    The adapter will need to be registered
    in the application's container as `dataAdapter:main`
  
    Example:
  
    ```javascript
    Application.initializer({
      name: "data-adapter",
  
      initialize: function(container, application) {
        application.register('data-adapter:main', DS.DataAdapter);

  /**
    Register a bound handlebars helper. Bound helpers behave similarly to regular
    handlebars helpers, with the added ability to re-render when the underlying data
    changes.
  
    ## Simple example
  
    ```javascript
    Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
      return Ember.String.capitalize(value);
    });
    ```
  
    The above bound helper can be used inside of templates as follows:
  
    ```handlebars
    {{capitalize name}}
    ```
  
    In this case, when the `name` property of the template's context changes,
    the rendered value of the helper will update to reflect this change.
  
    ## Example with options
  
    Like normal handlebars helpers, bound helpers have access to the options
    passed into the helper call.
  
    ```javascript
    Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
      var count = options.hash.count;
      var a = [];
      while(a.length < count) {
          a.push(value);
      }
      return a.join('');
    });
    ```
  
    This helper could be used in a template as follows:
  
    ```handlebars
    {{repeat text count=3}}
    ```
  
    ## Example with bound options
  
    Bound hash options are also supported. Example:
  
    ```handlebars
    {{repeat text count=numRepeats}}
    ```
  
    In this example, count will be bound to the value of
    the `numRepeats` property on the context. If that property
    changes, the helper will be re-rendered.
  
    ## Example with extra dependencies
  
    The `Ember.Handlebars.registerBoundHelper` method takes a variable length
    third parameter which indicates extra dependencies on the passed in value.
    This allows the handlebars helper to update when these dependencies change.
  
    ```javascript
    Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
      return value.get('name').toUpperCase();
    }, 'name');
    ```
  
    ## Example with multiple bound properties
  
    `Ember.Handlebars.registerBoundHelper` supports binding to
    multiple properties, e.g.:
  
    ```javascript
    Ember.Handlebars.registerBoundHelper('concatenate', function() {
      var values = Array.prototype.slice.call(arguments, 0, -1);
      return values.join('||');
    });
    ```
  
    Which allows for template syntax such as `{{concatenate prop1 prop2}}` or
    `{{concatenate prop1 prop2 prop3}}`. If any of the properties change,
    the helper will re-render.  Note that dependency keys cannot be
    using in conjunction with multi-property helpers, since it is ambiguous
    which property the dependent keys would belong to.
  
    ## Use with unbound helper
  
    The `{{unbound}}` helper can be used with bound helper invocations
    to render them in their unbound form, e.g.
  
    ```handlebars
    {{unbound capitalize name}}
    ```
  
    In this example, if the name property changes, the helper
    will not re-render.
  
    ## Use with blocks not supported
  
    Bound helpers do not support use with Handlebars blocks or
    the addition of child views of any kind.

    @for Ember.Handlebars

    @param {Function} fn

  function registerBoundHelper(name, fn) {
    var boundHelperArgs = slice.call(arguments, 1);
    var boundFn = _emberHtmlbarsCompatMakeBoundHelper.default.apply(this, boundHelperArgs);

    _emberHtmlbarsHelpers.default[name] = boundFn;

    Ember Helpers are functions that can compute values, and are used in templates.
    For example, this code calls a helper named `format-currency`:
  
    ```handlebars
    <div>{{format-currency cents currency="$"}}</div>
    ```
  
    Additionally a helper can be called as a nested helper (sometimes called a
    subexpression). In this example, the computed value of a helper is passed
    to a component named `show-money`:
  
    ```handlebars
    {{show-money amount=(format-currency cents currency="$")}}
    ```
  
    Helpers defined using a class must provide a `compute` function. For example:
  
    ```js
    export default Ember.Helper.extend({
      compute(params, hash) {
        let cents = params[0];
        let currency = hash.currency;
        return `${currency}${cents * 0.01}`;
      }
    });
    ```
  
    Each time the input to a helper changes, the `compute` function will be
    called again.
  
    As instances, these helpers also have access to the container an will accept
    injected dependencies.
  
    Additionally, class helpers can call `recompute` to force a new computation.

  /**
    The `{{#each}}` helper loops over elements in a collection. It is an extension
    of the base Handlebars `{{#each}}` helper.
  
    The default behavior of `{{#each}}` is to yield its inner block once for every
    item in an array.
  
    ```javascript
    var developers = [{name: 'Yehuda'},{name: 'Tom'}, {name: 'Paul'}];
    ```
  
    ```handlebars
    {{#each developers key="name" as |person|}}
      {{person.name}}
      {{! `this` is whatever it was outside the #each }}
    {{/each}}
    ```
  
    The same rules apply to arrays of primitives.
  
    ```javascript
    var developerNames = ['Yehuda', 'Tom', 'Paul']
    ```
  
    ```handlebars
    {{#each developerNames key="@index" as |name|}}
      {{name}}
    {{/each}}
    ```
  
    ### Specifying Keys
  
    The `key` option is used to tell Ember how to determine if the array being
    iterated over with `{{#each}}` has changed between renders. By helping Ember
    detect that some elements in the array are the same, DOM elements can be
    re-used, significantly improving rendering speed.
  
    For example, here's the `{{#each}}` helper with its `key` set to `id`:
  
    ```handlebars
    {{#each model key="id" as |item|}}
    {{/each}}
    ```
  
    When this `{{#each}}` re-renders, Ember will match up the previously rendered
    items (and reorder the generated DOM elements) based on each item's `id`
    property.
  
    By default the item's own reference is used.
  
    ### {{else}} condition
  
    `{{#each}}` can have a matching `{{else}}`. The contents of this block will render
    if the collection is empty.
  
    ```handlebars
    {{#each developers as |person|}}
      {{person.name}}
    {{else}}
      <p>Sorry, nobody is available for this task.</p>
    {{/each}}
    ```

   ```handlebars
    {{! will not render if foo is falsey}}
    {{#if foo}}
      Welcome to the {{foo.bar}}
    {{/if}}
    ```
  
    You can also specify a template to show if the property is falsey by using
    the `else` helper.
  
    ```handlebars
    {{!Is it raining outside?}}
    {{#if isRaining}}
      Yes, grab an umbrella!
    {{else}}
      No, it's lovely outside!
    {{/if}}

    You are also able to combine `else` and `if` helpers to create more complex
    conditional logic.
  
    ```handlebars
    {{#if isMorning}}
      Good morning
    {{else if isAfternoon}}
      Good afternoon
    {{else}}
      Good night
    {{/if}}
    ```
  
    You can use `if` inline to conditionally render a single property or string.
    This helper acts like a ternary operator. If the first property is truthy,
    the second argument will be displayed, if not, the third argument will be
    displayed
  
    ```handlebars
    {{if useLongGreeting "Hello" "Hi"}} Dave
    ```
  
    Finally, you can use the `if` helper inside another helper as a subexpression.

    Ember's implementation of HTMLBars creates an enriched scope.
  
    * self: same as HTMLBars, this field represents the dynamic lookup
      of root keys that are not special keywords or block arguments.
    * blocks: same as HTMLBars, a bundle of named blocks the layout
      can yield to.
    * component: indicates that the scope is the layout of a component,
      which is used to trigger lifecycle hooks for the component when
      one of the streams in its layout fires.
    * attrs: a map of key-value attributes sent in by the invoker of
      a template, and available in the component's layout.
    * locals: a map of locals, produced by block params (`as |a b|`)
    * localPresent: a map of available locals to avoid expensive
      `hasOwnProperty` checks.
  
    The `self` field has two special meanings:
  
    * If `self` is a view (`isView`), the actual HTMLBars `self` becomes
      the view's `context`. This is legacy semantics; components always
      use the component itself as the `this`.
    * If `self` is a view, two special locals are created: `view` and
      `controller`. These locals are legacy semantics.
    * If self has a `hasBoundController` property, it is coming from
      a legacy form of #with or #each
      (`{{#with something controller=someController}}`). This has
      the special effect of giving the child scope the supplied
      `controller` keyword, with an unrelated `self`. This is
      legacy functionality, as both the `view` and `controller`
      keywords have been deprecated.
  
    **IMPORTANT**: There are two places in Ember where the ambient
    controller is looked up. Both of those places use the presence
    of `scope.locals.view` to indicate that the controller lookup
    should be dynamic off of the ambient view. If `scope.locals.view`
    does not exist, the code assumes that it is inside of a top-level
    template (without a view) and uses the `self` itself as the
    controller. This means that if you remove `scope.locals.view`
    (perhaps because we are finally ready to shed the view keyword),
    there may be unexpected consequences on controller semantics.
    If this happens to you, I hope you find this comment. - YK & TD
  
    In practice, this means that with the exceptions of top-level
    view-less templates and the legacy `controller=foo` semantics,
    the controller hierarchy is managed dynamically by looking at
    the current view's `controller`.

  /**
    Execute the `debugger` statement in the current template's context.
  
    ```handlebars
    {{debugger}}
    ```
  
    When using the debugger helper you will have access to a `get` function. This
    function retrieves values available in the context of the template.
    For example, if you're wondering why a value `{{foo}}` isn't rendering as
    expected within a template, you could place a `{{debugger}}` statement and,
    when the `debugger;` breakpoint is hit, you can attempt to retrieve this value:
  
    ```
    > get('foo')
    ```
  
    `get` is also aware of keywords. So in this situation
  
    ```handlebars
    {{#each items as |item|}}
      {{debugger}}
    {{/each}}
    ```
  
    You'll be able to get values from the current item:
  
    ```
    > get('item.name')
    ```
  
    You can also access the context of the view to make sure it is the object that
    you expect:
  
    ```
    > context
    ```

  /**
    An `Ember.Binding` connects the properties of two objects so that whenever
    the value of one property changes, the other property will be changed also.
  
    ## Automatic Creation of Bindings with `/^*Binding/`-named Properties
  
    You do not usually create Binding objects directly but instead describe
    bindings in your class or object definition using automatic binding
    detection.
  
    Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
    instances. The value of this property should be a string representing a path
    to another object or a custom binding instance created using Binding helpers
    (see "One Way Bindings"):
  
    ```
    valueBinding: "MyApp.someController.title"
    ```
  
    This will create a binding from `MyApp.someController.title` to the `value`
    property of your object instance automatically. Now the two values will be
    kept in sync.
  
    ## One Way Bindings
  
    One especially useful binding customization you can use is the `oneWay()`
    helper. This helper tells Ember that you are only interested in
    receiving changes on the object you are binding from. For example, if you
    are binding to a preference and you want to be notified if the preference
    has changed, but your object will not be changing the preference itself, you
    could do:
  
    ```
    bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
    ```
  
    This way if the value of `MyApp.preferencesController.bigTitles` changes the
    `bigTitles` property of your object will change also. However, if you
    change the value of your `bigTitles` property, it will not update the
    `preferencesController`.
  
    One way bindings are almost twice as fast to setup and twice as fast to
    execute because the binding only has to worry about changes to one side.
  
    You should consider using one way bindings anytime you have an object that
    may be created frequently and you do not intend to change a property; only
    to monitor it for changes (such as in the example above).
  
    ## Adding Bindings Manually
  
    All of the examples above show you how to configure a custom binding, but the
    result of these customizations will be a binding template, not a fully active
    Binding instance. The binding will actually become active only when you
    instantiate the object the binding belongs to. It is useful however, to
    understand what actually happens when the binding is activated.
  
    For a binding to function it must have at least a `from` property and a `to`
    property. The `from` property path points to the object/key that you want to
    bind from while the `to` path points to the object/key you want to bind to.
  
    When you define a custom binding, you are usually describing the property
    you want to bind from (such as `MyApp.someController.value` in the examples
    above). When your object is created, it will automatically assign the value
    you want to bind `to` based on the name of your binding key. In the
    examples above, during init, Ember objects will effectively call
    something like this on your binding:
  
    ```javascript
    binding = Ember.Binding.from("valueBinding").to("value");
    ```
  
    This creates a new binding instance based on the template you provide, and
    sets the to path to the `value` property of the new object. Now that the
    binding is fully configured with a `from` and a `to`, it simply needs to be
    connected to become active. This is done through the `connect()` method:
  
    ```javascript
    binding.connect(this);
    ```
  
    Note that when you connect a binding you pass the object you want it to be
    connected to. This object will be used as the root for both the from and
    to side of the binding when inspecting relative paths. This allows the
    binding to be automatically inherited by subclassed objects as well.
  
    This also allows you to bind between objects using the paths you declare in
    `from` and `to`:
  
    ```javascript
    // Example 1
    binding = Ember.Binding.from("App.someObject.value").to("value");
    binding.connect(this);
  
    // Example 2
    binding = Ember.Binding.from("parentView.value").to("App.someObject.value");
    binding.connect(this);
    ```
  
    Now that the binding is connected, it will observe both the from and to side
    and relay changes.
  
    If you ever needed to do so (you almost never will, but it is useful to
    understand this anyway), you could manually create an active binding by
    using the `Ember.bind()` helper method. (This is the same method used by
    to setup your bindings on objects):
  
    ```javascript
    Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
    ```
  
    Both of these code fragments have the same effect as doing the most friendly
    form of binding creation like so:
  
    ```javascript
    MyApp.anotherObject = Ember.Object.create({
      valueBinding: "MyApp.someController.value",
  
      // OTHER CODE FOR THIS OBJECT...
    });
    ```
  
    Ember's built in binding creation method makes it easy to automatically
    create bindings for you. You should always use the highest-level APIs
    available, even if you understand how it works underneath.

  // COMPUTED PROPERTY

  /**
    A computed property transforms an object's function into a property.
  
    By default the function backing the computed property will only be called
    once and the result will be cached. You can specify various properties
    that your computed property depends on. This will force the cached
    result to be recomputed if the dependencies are modified.
  
    In the following example we declare a computed property (by calling
    `.property()` on the fullName function) and setup the property
    dependencies (depending on firstName and lastName). The fullName function
    will be called once (regardless of how many times it is accessed) as long
    as its dependencies have not changed. Once firstName or lastName are updated
    any future calls (or anything bound) to fullName will incorporate the new
    values.
  
    ```javascript
    var Person = Ember.Object.extend({
      // these will be supplied by `create`
      firstName: null,
      lastName: null,
  
      fullName: function() {
        var firstName = this.get('firstName');
        var lastName = this.get('lastName');
  
       return firstName + ' ' + lastName;
      }.property('firstName', 'lastName')
    });
  
    var tom = Person.create({
      firstName: 'Tom',
      lastName: 'Dale'
    });
  
    tom.get('fullName') // 'Tom Dale'
    ```
  
    You can also define what Ember should do when setting a computed property.
    If you try to set a computed property, it will be invoked with the key and
    value you want to set it to. You can also accept the previous value as the
    third parameter.
  
    ```javascript
    var Person = Ember.Object.extend({
      // these will be supplied by `create`
      firstName: null,
      lastName: null,
  
      fullName: function(key, value, oldValue) {
        // getter
        if (arguments.length === 1) {
          var firstName = this.get('firstName');
          var lastName = this.get('lastName');
  
          return firstName + ' ' + lastName;
  
        // setter
        } else {
          var name = value.split(' ');
  
          this.set('firstName', name[0]);
          this.set('lastName', name[1]);
  
          return value;
        }
      }.property('firstName', 'lastName')
    });
  
    var person = Person.create();

  /**
    This helper returns a new property descriptor that wraps the passed
    computed property function. You can use this helper to define properties
    with mixins or via `Ember.defineProperty()`.
  
    The function you pass will be used to both get and set property values.
    The function should accept two parameters, key and value. If value is not
    undefined you should set the value first. In either case return the
    current value of the property.
  
    A computed property defined in this way might look like this:
  
    ```js
    var Person = Ember.Object.extend({
      firstName: 'Betty',
      lastName: 'Jones',
  
      fullName: Ember.computed('firstName', 'lastName', function(key, value) {

      })
    });
  
    var client = Person.create();
  
    client.get('fullName'); // 'Betty Jones'
  
    client.set('lastName', 'Fuller');
    client.get('fullName'); // 'Betty Fuller'
    ```
  
    _Note: This is the preferred way to define computed properties when writing third-party
    libraries that depend on or use Ember, since there is no guarantee that the user
    will have prototype extensions enabled._
  
    You might use this method if you disabled
    [Prototype Extensions](http://emberjs.com/guides/configuring-ember/disabling-prototype-extensions/).
    The alternative syntax might look like this
    (if prototype extensions are enabled, which is the default behavior):
  
    ```js
    fullName: function () {
      return this.get('firstName') + ' ' + this.get('lastName');

  JavaScript (before ES6) does not have a Map implementation. Objects,

  Because Ember has a way to get a unique identifier for every object
  via `Ember.guidFor`, we can implement a performant Map with arbitrary
  keys. Because it is commonly used in low-level bookkeeping, Map is
  implemented as a pure JavaScript object for performance.

  This implementation follows the current iteration of the ES6 proposal for
  maps (http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets),
  with one exception:  as we do not have the luxury of in-VM iteration, we implement a
  forEach method for iteration.

  Map is mocked out to look like an Ember object, so you can do
  `Ember.Map.create()` for symmetry with other Ember classes.

    The `Ember.Mixin` class allows you to create mixins, whose properties can be
    added to other classes. For instance,
  
    ```javascript
    App.Editable = Ember.Mixin.create({
      edit: function() {
        console.log('starting to edit');
        this.set('isEditing', true);

    // .extend.
    App.CommentView = Ember.View.extend(App.Editable, {
      template: Ember.Handlebars.compile('{{#if view.isEditing}}...{{else}}...{{/if}}')
    });
  
    commentView = App.CommentView.create();
    commentView.edit(); // outputs 'starting to edit'
    ```
  
    Note that Mixins are created with `Ember.Mixin.create`, not
    `Ember.Mixin.extend`.
  
    Note that mixins extend a constructor's prototype so arrays and object literals
    defined as properties will be shared amongst objects that implement the mixin.
    If you want to define a property in a mixin that is not shared, you can define
    it either as a computed property or have it be created on initialization of the object.
  
    ```javascript
    //filters array will be shared amongst any object implementing mixin
    App.Filterable = Ember.Mixin.create({
      filters: Ember.A()
    });
  
    //filters will be a separate  array for every object implementing the mixin
    App.Filterable = Ember.Mixin.create({
      filters: Ember.computed(function() {return Ember.A();})
    });
  
    //filters will be created as a separate array during the object's initialization
    App.Filterable = Ember.Mixin.create({
      init: function() {
        this._super.apply(this, arguments);
        this.set("filters", Ember.A());

    NOTE: This is a low-level method used by other parts of the API. You almost
    never want to call this method directly. Instead you should use
    `Ember.mixin()` to define new properties.
  
    Defines a property on an object. This method works much like the ES5
    `Object.defineProperty()` method except that it can also accept computed
    properties and other special descriptors.
  
    Normally this method takes only three parameters. However if you pass an
    instance of `Descriptor` as the third param then you can pass an
    optional value as the fourth parameter. This is often more efficient than
    creating new descriptor hashes for each property.
  
    ## Examples
  
    ```javascript
    // ES5 compatible mode
    Ember.defineProperty(contact, 'firstName', {
      writable: true,
      configurable: false,
      enumerable: true,
      value: 'Charles'
    });
  
    // define a simple property
    Ember.defineProperty(contact, 'lastName', undefined, 'Jolley');
  
    // define a computed property
    Ember.defineProperty(contact, 'fullName', Ember.computed(function() {
      return this.firstName+' '+this.lastName;
    }).property('firstName', 'lastName'));
    ```
  
    @private
    @method defineProperty
    @for Ember
    @param {Object} obj the object to define this property on. This may be a prototype.
    @param {String} keyName the name of the property
    @param {Descriptor} [desc] an instance of `Descriptor` (typically a
      computed property) or an ES5 descriptor.
      You must provide this or `data` but not both.
    @param {*} [data] something other than a descriptor, that will
      become the explicit value of this property.

    Allows you to specify which context to call the specified function in while
    adding the execution of that function to the Ember run loop. This ability
    makes this method a great way to asynchronously integrate third-party libraries
    into your Ember application.
  
    `run.bind` takes two main arguments, the desired context and the function to
    invoke in that context. Any additional arguments will be supplied as arguments
    to the function that is passed in.
  
    Let's use the creation of a TinyMCE component as an example. Currently,
    TinyMCE provides a setup configuration option we can use to do some processing
    after the TinyMCE instance is initialized but before it is actually rendered.
    We can use that setup option to do some additional setup for our component.
    The component itself could look something like the following:
  
    ```javascript
    App.RichTextEditorComponent = Ember.Component.extend({
      initializeTinyMCE: Ember.on('didInsertElement', function() {
        tinymce.init({
          selector: '#' + this.$().prop('id'),
          setup: Ember.run.bind(this, this.setupEditor)
        });
      }),
  
      setupEditor: function(editor) {
        this.set('editor', editor);
  
        editor.on('change', function() {
          console.log('content changed!');
        });
      }
    });
    ```
  
    In this example, we use Ember.run.bind to bind the setupEditor method to the
    context of the App.RichTextEditorComponent and to have the invocation of that
    method be safely handled and executed by the Ember run loop.
  
    @method bind

    Schedules an item to run from within a separate run loop, after
    control has been returned to the system. This is equivalent to calling
    `run.later` with a wait time of 1ms.
  
    ```javascript
    run.next(myContext, function() {
      // code to be executed in the next run loop,
      // which will be scheduled after the current one
    });
    ```
  
    Multiple operations scheduled with `run.next` will coalesce
    into the same later run loop, along with any other operations
    scheduled by `run.later` that expire right around the same
    time that `run.next` operations will fire.
  
    Note that there are often alternatives to using `run.next`.
    For instance, if you'd like to schedule an operation to happen
    after all DOM element operations have completed within the current
    run loop, you can make use of the `afterRender` run loop queue (added
    by the `ember-views` package, along with the preceding `render` queue
    where all the DOM element operations happen). Example:
  
    ```javascript
    App.MyCollectionView = Ember.CollectionView.extend({
      didInsertElement: function() {
        run.scheduleOnce('afterRender', this, 'processChildElements');
      },
      processChildElements: function() {
        // ... do something with collectionView's child view
        // elements after they've finished rendering, which
        // can't be done within the CollectionView's
        // `didInsertElement` hook because that gets run
        // before the child elements have been added to the DOM.
      }
    });
    ```
  
    One benefit of the above approach compared to using `run.next` is
    that you will be able to perform DOM/CSS operations before unprocessed
    elements are rendered to the screen, which may prevent flickering or
    other artifacts caused by delaying processing until after rendering.
  
    The other major benefit to the above approach is that `run.next`
    introduces an element of non-determinism, which can make things much
    harder to test, due to its reliance on `setTimeout`; it's much harder
    to guarantee the order of scheduled operations when they are scheduled
    outside of the current run loop, i.e. with `run.next`.

    This method should be used when an event may be called multiple times
    but the action should only be called once when the event is done firing.
    A common example is for scroll events where you only want updates to
    happen once scrolling has ceased.

    Strongly hint runtimes to intern the provided string.
  
    When do I need to use this function?
  
    For the most part, never. Pre-mature optimization is bad, and often the
    runtime does exactly what you need it to, and more often the trade-off isn't
    worth it.
  
    Why?
  
    Runtimes store strings in at least 2 different representations:
    Ropes and Symbols (interned strings). The Rope provides a memory efficient
    data-structure for strings created from concatenation or some other string
    manipulation like splitting.
  
    Unfortunately checking equality of different ropes can be quite costly as
    runtimes must resort to clever string comparison algorithms. These
    algorithms typically cost in proportion to the length of the string.
    Luckily, this is where the Symbols (interned strings) shine. As Symbols are
    unique by their string content, equality checks can be done by pointer
    comparison.
  
    How do I know if my string is a rope or symbol?
  
    Typically (warning general sweeping statement, but truthy in runtimes at
    present) static strings created as part of the JS source are interned.
    Strings often used for comparisons can be interned at runtime if some
    criteria are met.  One of these criteria can be the size of the entire rope.
    For example, in chrome 38 a rope longer then 12 characters will not
    intern, nor will segments of that rope.

    @deprecated

    In order to store defaults for a class, a prototype may need to create
    a default meta object, which will be inherited by any objects instantiated
    from the class's constructor.
  
    However, the properties of that meta object are only shallow-cloned,
    so if a property is a hash (like the event system's `listeners` hash),
    it will by default be shared across all instances of that class.
  
    This method allows extensions to deeply clone a series of nested hashes or
    other complex objects. For instance, the event system might pass
    `['listeners', 'foo:change', 'ember157']` to `prepareMetaPath`, which will
    walk down the keys provided.
  
    For each key, if the key does not exist, it is created. If it already
    exists and it was inherited from its constructor, the constructor's
    key is cloned.
  
    You can also pass false for `writable`, which will simply return
    undefined if `prepareMetaPath` discovers any part of the path that
    shared or undefined.

  /**
    The `{{action}}` helper provides a useful shortcut for registering an HTML
    element within a template for a single DOM event and forwarding that
    interaction to the template's controller or specified `target` option.
  
    If the controller does not implement the specified action, the event is sent
    to the current route, and it bubbles up the route hierarchy from there.
  
    For more advanced event handling see [Ember.Component](/api/classes/Ember.Component.html)
  
  
    ### Use
    Given the following application Handlebars template on the page
  
    ```handlebars
    <div {{action 'anActionName'}}>
      click me
    </div>
    ```
  
    And application code
  
    ```javascript
    App.ApplicationController = Ember.Controller.extend({
      actions: {
        anActionName: function() {
        }
      }
    });
    ```
  
    Will result in the following rendered HTML
  
    ```html
    <div class="ember-view">
      <div data-ember-action="1">
        click me
      </div>
    </div>
    ```
  
    Clicking "click me" will trigger the `anActionName` action of the
    `App.ApplicationController`. In this case, no additional parameters will be passed.
  
    If you provide additional parameters to the helper:
  
    ```handlebars
    <button {{action 'edit' post}}>Edit</button>
    ```
  
    Those parameters will be passed along as arguments to the JavaScript
    function implementing the action.
  
    ### Event Propagation
  
    Events triggered through the action helper will automatically have
    `.preventDefault()` called on them. You do not need to do so in your event
    handlers. If you need to allow event propagation (to handle file inputs for
    example) you can supply the `preventDefault=false` option to the `{{action}}` helper:
  
    ```handlebars
    <div {{action "sayHello" preventDefault=false}}>
      <input type="file" />
      <input type="checkbox" />
    </div>
    ```
  
    To disable bubbling, pass `bubbles=false` to the helper:
  
    ```handlebars
    <button {{action 'edit' post bubbles=false}}>Edit</button>
    ```
  
    If you need the default handler to trigger you should either register your
    own event handler, or use event methods on your view class. See [Ember.View](/api/classes/Ember.View.html)
    'Responding to Browser Events' for more information.
  
    ### Specifying DOM event type
  
    By default the `{{action}}` helper registers for DOM `click` events. You can
    supply an `on` option to the helper to specify a different DOM event name:
  
    ```handlebars
    <div {{action "anActionName" on="double-click"}}>
      click me
    </div>
    ```
  
    See `Ember.View` 'Responding to Browser Events' for a list of
    acceptable DOM event names.
  
    ### Specifying whitelisted modifier keys
  
    By default the `{{action}}` helper will ignore click event with pressed modifier
    keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.
  
    ```handlebars
    <div {{action "anActionName" allowedKeys="alt"}}>
      click me
    </div>
    ```
  
    This way the `{{action}}` will fire when clicking with the alt key pressed down.
  
    Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys.
  
    ```handlebars
    <div {{action "anActionName" allowedKeys="any"}}>
      click me with any key pressed
    </div>
    ```
  
    ### Specifying a Target
  
    There are several possible target objects for `{{action}}` helpers:
  
    In a typical Ember application, where templates are managed through use of the
    `{{outlet}}` helper, actions will bubble to the current controller, then
    to the current route, and then up the route hierarchy.
  
    Alternatively, a `target` option can be provided to the helper to change
    which object will receive the method call. This option must be a path
    to an object, accessible in the current context:
  
    ```handlebars
    {{! the application template }}
    <div {{action "anActionName" target=view}}>
      click me
    </div>
    ```
  
    ```javascript
    App.ApplicationView = Ember.View.extend({
      actions: {
        anActionName: function() {}
      }
    });
  
    ```
  
    ### Additional Parameters
  
    You may specify additional parameters to the `{{action}}` helper. These
    parameters are passed along as the arguments to the JavaScript function
    implementing the action.
  
    ```handlebars
    {{#each people as |person|}}
      <div {{action "edit" person}}>
        click me
      </div>
    {{/each}}
    ```
  
    Clicking "click me" will trigger the `edit` method on the current controller
    with the value of `person` as a parameter.

  /**
    The `{{link-to}}` helper renders a link to the supplied
    `routeName` passing an optionally supplied model to the
    route as its `model` context of the route. The block
    for `{{link-to}}` becomes the innerHTML of the rendered
    element:
  
    ```handlebars
    {{#link-to 'photoGallery'}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    You can also use an inline form of `{{link-to}}` helper by
    passing the link text as the first argument
    to the helper:
  
    ```handlebars
    {{link-to 'Great Hamster Photos' 'photoGallery'}}
    ```
  
    Both will result in:
  
    ```html
    <a href="/hamster-photos">
      Great Hamster Photos
    </a>
    ```
  
    ### Supplying a tagName
    By default `{{link-to}}` renders an `<a>` element. This can
    be overridden for a single use of `{{link-to}}` by supplying
    a `tagName` option:
  
    ```handlebars
    {{#link-to 'photoGallery' tagName="li"}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    ```html
    <li>
      Great Hamster Photos
    </li>
    ```
  
    To override this option for your entire application, see
    "Overriding Application-wide Defaults".
  
    ### Disabling the `link-to` helper
    By default `{{link-to}}` is enabled.
    any passed value to `disabled` helper property will disable the `link-to` helper.
  
    static use: the `disabled` option:
  
    ```handlebars
    {{#link-to 'photoGallery' disabled=true}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    dynamic use: the `disabledWhen` option:
  
    ```handlebars
    {{#link-to 'photoGallery' disabledWhen=controller.someProperty}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    any passed value to `disabled` will disable it except `undefined`.
    to ensure that only `true` disable the `link-to` helper you can
    override the global behaviour of `Ember.LinkComponent`.
  
    ```javascript
    Ember.LinkComponent.reopen({
      disabled: Ember.computed(function(key, value) {
        if (value !== undefined) {
          this.set('_isDisabled', value === true);
        }
        return value === true ? get(this, 'disabledClass') : false;
      })
    });
    ```
  
    see "Overriding Application-wide Defaults" for more.
  
    ### Handling `href`
    `{{link-to}}` will use your application's Router to
    fill the element's `href` property with a url that
    matches the path to the supplied `routeName` for your
    router's configured `Location` scheme, which defaults
    to Ember.HashLocation.
  
    ### Handling current route
    `{{link-to}}` will apply a CSS class name of 'active'
    when the application's current route matches
    the supplied routeName. For example, if the application's
    current route is 'photoGallery.recent' the following
    use of `{{link-to}}`:
  
    ```handlebars
    {{#link-to 'photoGallery.recent'}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    will result in
  
    ```html
    <a href="/hamster-photos/this-week" class="active">
      Great Hamster Photos
    </a>
    ```
  
    The CSS class name used for active classes can be customized
    for a single use of `{{link-to}}` by passing an `activeClass`
    option:
  
    ```handlebars
    {{#link-to 'photoGallery.recent' activeClass="current-url"}}
      Great Hamster Photos
    {{/link-to}}
    ```
  
    ```html
    <a href="/hamster-photos/this-week" class="current-url">
      Great Hamster Photos
    </a>
    ```
  
    To override this option for your entire application, see
    "Overriding Application-wide Defaults".
  
    ### Supplying a model
    An optional model argument can be used for routes whose
    paths contain dynamic segments. This argument will become
    the model context of the linked route:
  
    ```javascript
    App.Router.map(function() {
      this.route("photoGallery", {path: "hamster-photos/:photo_id"});
    });
    ```
  
    ```handlebars
    {{#link-to 'photoGallery' aPhoto}}
      {{aPhoto.title}}
    {{/link-to}}
    ```
  
    ```html
    <a href="/hamster-photos/42">
      Tomster
    </a>
    ```
  
    ### Supplying multiple models
    For deep-linking to route paths that contain multiple
    dynamic segments, multiple model arguments can be used.
    As the router transitions through the route path, each
    supplied model argument will become the context for the
    route with the dynamic segments:
  
    ```javascript
    App.Router.map(function() {
      this.route("photoGallery", { path: "hamster-photos/:photo_id" }, function() {
        this.route("comment", {path: "comments/:comment_id"});
      });
    });
    ```
    This argument will become the model context of the linked route:
  
    ```handlebars
    {{#link-to 'photoGallery.comment' aPhoto comment}}
      {{comment.body}}
    {{/link-to}}
    ```
  
    ```html
    <a href="/hamster-photos/42/comments/718">
      A+++ would snuggle again.
    </a>
    ```
  
    ### Supplying an explicit dynamic segment value
    If you don't have a model object available to pass to `{{link-to}}`,
    an optional string or integer argument can be passed for routes whose
    paths contain dynamic segments. This argument will become the value
    of the dynamic segment:
  
    ```javascript
    App.Router.map(function() {
      this.route("photoGallery", { path: "hamster-photos/:photo_id" });
    });
    ```
  
    ```handlebars
    {{#link-to 'photoGallery' aPhotoId}}
      {{aPhoto.title}}
    {{/link-to}}
    ```
  
    ```html

    </a>
    ```
  
    When transitioning into the linked route, the `model` hook will
    be triggered with parameters including this passed identifier.
  
    ### Allowing Default Action
  
   By default the `{{link-to}}` helper prevents the default browser action
   by calling `preventDefault()` as this sort of action bubbling is normally
   handled internally and we do not want to take the browser to a new URL (for
   example).
  
   If you need to override this behavior specify `preventDefault=false` in
   your template:
  
    ```handlebars
    {{#link-to 'photoGallery' aPhotoId preventDefault=false}}
      {{aPhotoId.title}}
    {{/link-to}}
    ```
  
    ### Overriding attributes
    You can override any given property of the Ember.LinkComponent
    that is generated by the `{{link-to}}` helper by passing
    key/value pairs, like so:
  
    ```handlebars
    {{#link-to  aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}}
      Uh-mazing!
    {{/link-to}}
    ```
  
    See [Ember.LinkComponent](/api/classes/Ember.LinkComponent.html) for a
    complete list of overrideable properties. Be sure to also
    check out inherited properties of `LinkComponent`.
  
    ### Overriding Application-wide Defaults
    ``{{link-to}}`` creates an instance of Ember.LinkComponent
    for rendering. To override options for your entire
    application, reopen Ember.LinkComponent and supply the
    desired values:
  
    ``` javascript
    Ember.LinkComponent.reopen({
      activeClass: "is-active",
      tagName: 'li'
    })
    ```
  
    It is also possible to override the default event in
    this manner:
  
    ``` javascript
    Ember.LinkComponent.reopen({
      eventName: 'customEventName'
    });
    ```
  
    @method link-to
    @for Ember.Templates.helpers
    @param {String} routeName
    @param {Object} [context]*
    @param [options] {Object} Handlebars key/value pairs of options, you can override any property of Ember.LinkComponent
    @return {String} HTML string
    @see {Ember.LinkComponent}

  /**
    Ember.Location returns an instance of the correct implementation of
    the `location` API.
  
    ## Implementations
  
    You can pass an implementation name (`hash`, `history`, `none`) to force a
    particular implementation to be used in your application.
  
    ### HashLocation
  
    Using `HashLocation` results in URLs with a `#` (hash sign) separating the
    server side URL portion of the URL from the portion that is used by Ember.
    This relies upon the `hashchange` event existing in the browser.
  
    Example:
  
    ```javascript
    App.Router.map(function() {
      this.route('posts', function() {
        this.route('new');
      });
    });
  
    App.Router.reopen({
      location: 'hash'
    });
    ```
  
    This will result in a posts.new url of `/#/posts/new`.
  
    ### HistoryLocation
  
    Using `HistoryLocation` results in URLs that are indistinguishable from a
    standard URL. This relies upon the browser's `history` API.
  
    Example:
  
    ```javascript
    App.Router.map(function() {
      this.route('posts', function() {
        this.route('new');
      });
    });
  
    App.Router.reopen({
      location: 'history'
    });
    ```
  
    This will result in a posts.new url of `/posts/new`.
  
    Keep in mind that your server must serve the Ember app at all the routes you
    define.
  
    ### AutoLocation
  
    Using `AutoLocation`, the router will use the best Location class supported by
    the browser it is running in.
  
    Browsers that support the `history` API will use `HistoryLocation`, those that
    do not, but still support the `hashchange` event will use `HashLocation`, and
    in the rare case neither is supported will use `NoneLocation`.
  
    Example:
  
    ```javascript
    App.Router.map(function() {
      this.route('posts', function() {
        this.route('new');
      });
    });
  
    App.Router.reopen({
      location: 'auto'
    });
    ```
  
    This will result in a posts.new url of `/posts/new` for modern browsers that
    support the `history` api or `/#/posts/new` for older ones, like Internet
    Explorer 9 and below.
  
    When a user visits a link to your application, they will be automatically
    upgraded or downgraded to the appropriate `Location` class, with the URL
    transformed accordingly, if needed.
  
    Keep in mind that since some of your users will use `HistoryLocation`, your
    server must serve the Ember app at all the routes you define.
  
    ### NoneLocation
  
    Using `NoneLocation` causes Ember to not store the applications URL state
    in the actual URL. This is generally used for testing purposes, and is one
    of the changes made when calling `App.setupForTesting()`.
  
    ## Location API
  
    Each location implementation must provide the following methods:
  
    * implementation: returns the string name used to reference the implementation.
    * getURL: returns the current URL.
    * setURL(path): sets the current URL.
    * replaceURL(path): replace the current URL (optional).
    * onUpdateURL(callback): triggers the callback when the URL changes.
    * formatURL(url): formats `url` to be placed into `href` attribute.
    * detect() (optional): instructs the location to do any feature detection
        necessary. If the location needs to redirect to a different URL, it
        can cancel routing by setting the `cancelRouterSetup` property on itself
        to `false`.
  
    Calling setURL or replaceURL will not trigger onUpdateURL callbacks.

       A good example is preventing navigation when a form is

            }

        }
      });
      ```
       You can also redirect elsewhere by calling
      `this.transitionTo('elsewhere')` from within `willTransition`.
      Note that `willTransition` will not be fired for the
      redirecting `transitionTo`, since `willTransition` doesn't
      fire when there is already a transition underway. If you want
      subsequent `willTransition` actions to fire for the redirecting

      When attempting to transition into a route, any of the hooks

      action will be fired on the partially-entered routes, allowing
      for per-route error handling logic, or shared error handling
      logic defined on a parent route.
       Here is an example of an error handler that will be invoked
      for rejected promises from the various hooks on the route,
      as well as any unhandled errors from child routes:
       ```javascript
      App.AdminRoute = Ember.Route.extend({
        beforeModel: function() {
          return Ember.RSVP.reject('bad things!');
        },

          error: function(error, transition) {
            // Assuming we got here due to the error in `beforeModel`,
            // we can expect that error === "bad things!",
            // but a promise model rejecting would also
            // call this hook, as would any errors encountered
            // in `afterModel`.
             // The `error` hook is also provided the failed
            // `transition`, which can be stored and later
            // `.retry()`d if desired.
             this.transitionTo('login');
          }
        }
      });
      ```
       `error` actions that bubble up all the way to `ApplicationRoute`
      will fire a default error handler that logs the error. You can
      specify your own global default error handler by overriding the
      `error` handler on `ApplicationRoute`:
       ```javascript
      App.ApplicationRoute = Ember.Route.extend({
        actions: {
          error: function(error, transition) {
            this.controllerFor('banner').displayError(error.message);

        });
      });
       this.transitionTo('blogComment', aPost, aComment);
      this.transitionTo('blogComment', 1, 13);
      ```
       It is also possible to pass a URL (a string that starts with a
      `/`). This is intended for testing and debugging purposes and
      should rarely be used in production code.
       ```javascript
      this.transitionTo('/');
      this.transitionTo('/blog/post/1/comment/13');
      this.transitionTo('/blog/posts?sort=title');
      ```
       An options hash with a `queryParams` property may be provided as
      the final argument to add query parameters to the destination URL.
       ```javascript
      this.transitionTo('blogPost', 1, {
        queryParams: {showComments: 'true'}
      });
       // if you just want to transition the query parameters without changing the route
      this.transitionTo({queryParams: {sort: 'date'}});
      ```
       See also 'replaceWith'.
       Simple Transition Example
       ```javascript
      App.Router.map(function() {
        this.route('index');
        this.route('secret');
        this.route('fourOhFour', { path: '*:' });
      });
       App.IndexRoute = Ember.Route.extend({
        actions: {
          moveToSecret: function(context) {
            if (authorized()) {
              this.transitionTo('secret', context);
            } else {
              this.transitionTo('fourOhFour');
            }
          }
        }
      });
      ```
       Transition to a nested route
       ```javascript
      App.Router.map(function() {
        this.route('articles', { path: '/articles' }, function() {
          this.route('new');
        });
      });
       App.IndexRoute = Ember.Route.extend({
        actions: {
          transitionToNewArticle: function() {
            this.transitionTo('articles.new');
          }
        }
      });
      ```
       Multiple Models Example
       ```javascript
      App.Router.map(function() {
        this.route('index');
         this.route('breakfast', { path: ':breakfastId' }, function() {
          this.route('cereal', { path: ':cerealId', resetNamespace: true });
        });
      });
       App.IndexRoute = Ember.Route.extend({
        actions: {
          moveToChocolateCereal: function() {
            var cereal = { cerealId: 'ChocolateYumminess' };
            var breakfast = { breakfastId: 'CerealAndMilk' };
             this.transitionTo('cereal', breakfast, cereal);
          }
        }
      });
      ```
       Nested Route with Query String Example
       ```javascript
      App.Router.map(function() {
        this.route('fruits', function() {
          this.route('apples');
        });

    /**
      This hook is the first of the route entry validation hooks
      called when an attempt is made to transition into a route
      or one of its children. It is called before `model` and
      `afterModel`, and is appropriate for cases when:
       1) A decision can be made to redirect elsewhere without
         needing to resolve the model first.
      2) Any async operations need to occur first before the
         model is attempted to be resolved.
       This hook is provided the current `transition` attempt
      as a parameter, which can be used to `.abort()` the transition,
      save it for a later `.retry()`, or retrieve values set
      on it from a previous hook. You can also just call
      `this.transitionTo` to another route to implicitly
      abort the `transition`.
       You can return a promise from this hook to pause the
      transition until the promise resolves (or rejects). This could
      be useful, for instance, for retrieving async code from
      the server that is required to enter a route.
       ```javascript
      App.PostRoute = Ember.Route.extend({
        beforeModel: function(transition) {
          if (!App.Post) {
            return Ember.$.getScript('/models/post.js');
          }
        }
      });
      ```
       If `App.Post` doesn't exist in the above example,
      `beforeModel` will use jQuery's `getScript`, which
      returns a promise that resolves after the server has
      successfully retrieved and executed the code from the
      server. Note that if an error were to occur, it would
      be passed to the `error` hook on `Ember.Route`, but
      it's also possible to handle errors specific to
      `beforeModel` right from within the hook (to distinguish
      from the shared error handling behavior of the `error`
      hook):
       ```javascript
      App.PostRoute = Ember.Route.extend({
        beforeModel: function(transition) {
          if (!App.Post) {
            var self = this;
            return Ember.$.getScript('post.js').then(null, function(e) {
              self.transitionTo('help');
               // Note that the above transitionTo will implicitly
              // halt the transition. If you were to return
              // nothing from this promise reject handler,
              // according to promise semantics, that would
              // convert the reject into a resolve and the
              // transition would continue. To propagate the
              // error so that it'd be handled by the `error`
              // hook, you would have to
              return Ember.RSVP.reject(e);
            });
          }
        }
      });
      ```

      distinction in the case that, from one of these hooks, a
      redirect into a child route of this route occurs: redirects
      from `afterModel` essentially invalidate the current attempt
      to enter this route, and will result in this route's `beforeModel`,
      `model`, and `afterModel` hooks being fired again within
      the new, redirecting transition. Redirects that occur within
      the `redirect` hook, on the other hand, will _not_ cause
      these hooks to be fired again the second time around; in

      A hook you can implement to convert the URL into the model for

       ```javascript
      App.Router.map(function() {
        this.route('post', { path: '/posts/:post_id' });
      });
      ```
       The model for the `post` route is `store.find('post', params.post_id)`.
       By default, if your route has a dynamic segment ending in `_id`:
       * The model class is determined from the segment (`post_id`'s
        class is `App.Post`)
      * The find method is called on the model class with the value of
        the dynamic segment.
       Note that for routes with dynamic segments, this hook is not always
      executed. If the route is entered through a transition (e.g. when
      using the `link-to` Handlebars helper or the `transitionTo` method
      of routes), and a model context is already provided this hook
      is not called.
       A model context does not include a primitive string or number,
      which does cause the model hook to be called.
       Routes without dynamic segments will always execute the model hook.
       ```javascript
      // no dynamic segment, model hook always called
      this.transitionTo('posts');
       // model passed in, so model hook not called
      thePost = store.find('post', 1);
      this.transitionTo('post', thePost);
       // integer passed in, model hook is called
      this.transitionTo('post', 1);
       // model id passed in, model hook is called
      // useful for forcing the hook to execute
      thePost = store.find('post', 1);
      this.transitionTo('post', thePost.id);
      ```
        This hook follows the asynchronous/promise semantics
      described in the documentation for `beforeModel`. In particular,
      if a promise returned from `model` fails, the error will be
      handled by the `error` hook on `Ember.Route`.
       Example
       ```javascript
      App.PostRoute = Ember.Route.extend({
        model: function(params) {
          return this.store.find('post', params.post_id);

    /**
      A hook you can use to setup the controller for the current route.
       This method is called with the controller for the current route and the
      model supplied by the `model` hook.
       By default, the `setupController` hook sets the `model` property of
      the controller to the `model`.
       If you implement the `setupController` hook in your Route, it will
      prevent this default behavior. If you want to preserve that behavior
      when implementing your `setupController` function, make sure to call
      `_super`:
       ```javascript
      App.PhotosRoute = Ember.Route.extend({
        model: function() {
          return this.store.find('photo');
        },
         setupController: function (controller, model) {
          // Call _super for default behavior
          this._super(controller, model);
          // Implement your custom setup after
          this.controllerFor('application').set('showingPhotos', true);
        }
      });
      ```
       The provided controller will be one resolved based on the name
      of this route.
       If no explicit controller is defined, Ember will automatically create
      an appropriate controller for the model.
       * if the model is an `Ember.Array` (including record arrays from Ember
        Data), the controller is an `Ember.ArrayController`.
      * otherwise, the controller is basic `Ember.Controller`.
       As an example, consider the router:
       ```javascript
      App.Router.map(function() {
        this.route('post', { path: '/posts/:post_id' });
      });
      ```
       For the `post` route, a controller named `App.PostController` would
      be used if it is defined. If it is not defined, a basic `Ember.Controller`
      instance would be used.
       Example
       ```javascript
      App.PostRoute = Ember.Route.extend({
        setupController: function(controller, model) {
          controller.set('model', model);

      this.render();
    },

    /**
      `render` is used to render a template into a region of another template
      (indicated by an `{{outlet}}`). `render` is used both during the entry
      phase of routing (via the `renderTemplate` hook) and later in response to
      user interaction.
       For example, given the following minimal router and templates:
       ```javascript
      Router.map(function() {
        this.route('photos');
      });
      ```
       ```handlebars
      <!-- application.hbs -->
      <div class='something-in-the-app-hbs'>
        {{outlet "anOutletName"}}
      </div>
      ```
       ```handlebars
      <!-- photos.hbs -->
      <h1>Photos</h1>
      ```
       You can render `photos.hbs` into the `"anOutletName"` outlet of
      `application.hbs` by calling `render`:
       ```javascript
      // posts route
      Ember.Route.extend({
        renderTemplate: function() {
          this.render('photos', {
            into: 'application',
            outlet: 'anOutletName'
          })
        }
      });
      ```
       `render` additionally allows you to supply which `view`, `controller`, and
      `model` objects should be loaded and associated with the rendered template.
        ```javascript
      // posts route
      Ember.Route.extend({
        renderTemplate: function(controller, model){
          this.render('posts', {    // the template to render, referenced by name
            into: 'application',    // the template to render into, referenced by name
            outlet: 'anOutletName', // the outlet inside `options.template` to render into.
            view: 'aViewName',      // the view to use for this template, referenced by name
            controller: 'someControllerName', // the controller to use for this template, referenced by name
            model: model            // the model to set on `options.controller`.
          })
        }
      });
      ```
       The string values provided for the template name, view, and controller
      will eventually pass through to the resolver for lookup. See
      Ember.Resolver for how these are mapped to JavaScript objects in your
      application.
       Not all options need to be passed to `render`. Default values will be used
      based on the name of the route specified in the router or the Route's
      `controllerName`, `viewName` and `templateName` properties.
       For example:
       ```javascript
      // router
      Router.map(function() {
        this.route('index');
        this.route('post', { path: '/posts/:post_id' });
      });
      ```
       ```javascript
      // post route
      PostRoute = App.Route.extend({
        renderTemplate: function() {
          this.render(); // all defaults apply
        }
      });
      ```
       The name of the `PostRoute`, defined by the router, is `post`.
       The following equivalent default options will be applied when
      the Route calls `render`:
       ```javascript
      //
      this.render('post', {  // the template name associated with 'post' Route
        into: 'application', // the parent route to 'post' Route
        outlet: 'main',      // {{outlet}} and {{outlet 'main' are synonymous}},
        view: 'post',        // the view associated with the 'post' Route
        controller: 'post',  // the controller associated with the 'post' Route
      })
      ```
       By default the controller's `model` will be the route's model, so it does not
      need to be passed unless you wish to change which model is being used.
       @method render
      @param {String} name the name of the template to render
      @param {Object} [options] the options
      @param {String} [options.into] the template to render into,

      The `Router.map` function allows you to define mappings from URLs to routes
      in your application. These mappings are defined within the
      supplied callback function using `this.route`.
       The first parameter is the name of the route which is used by default as the
      path name as well.
       The second parameter is the optional options hash. Available options are:
        * `path`: allows you to provide your own path as well as mark dynamic
          segments.
        * `resetNamespace`: false by default; when nesting routes, ember will
          combine the route names to form the fully-qualified route name, which is
          used with `{{link-to}}` or manually transitioning to routes. Setting
          `resetNamespace: true` will cause the route not to inherit from its
          parent route's names. This is handy for resources which can be accessed
          in multiple places as well as preventing extremely long route names.
          Keep in mind that the actual URL path behavior is still retained.
       The third parameter is a function, which can be used to nest routes.
      Nested routes, by default, will have the parent route tree's route name and
      path prepended to it's own.
       ```javascript
      App.Router.map(function(){
        this.route('post', { path: '/post/:post_id' }, function() {
          this.route('edit');
          this.route('comments', { resetNamespace: true }, function() {
            this.route('new');

    The callback method you provide should have the following signature:
  
    ```javascript
    function(itemA, itemB);
    ```
  
    - `itemA` the first item to compare.
    - `itemB` the second item to compare.
  
    This function should return negative number (e.g. `-1`) when `itemA` should come before
    `itemB`. It should return positive number (e.g. `1`) when `itemA` should come after
    `itemB`. If the `itemA` and `itemB` are equal this function should return `0`.
  
    Therefore, if this function is comparing some numeric values, simple `itemA - itemB` or
    `itemA.get( 'foo' ) - itemB.get( 'foo' )` can be used instead of series of `if`.

  exports.arrayControllerDeprecation = arrayControllerDeprecation;
  /**
    `Ember.ArrayController` provides a way for you to publish a collection of
    objects so that you can easily bind to the collection from a Handlebars
    `#each` helper, an `Ember.CollectionView`, or other controllers.
  
    The advantage of using an `ArrayController` is that you only have to set up
    your view bindings once; to change what's displayed, simply swap out the
    `model` property on the controller.
  
    For example, imagine you wanted to display a list of items fetched via an XHR
    request. Create an `Ember.ArrayController` and set its `model` property:
  
    ```javascript
    MyApp.listController = Ember.ArrayController.create();
  
    $.get('people.json', function(data) {
      MyApp.listController.set('model', data);
    });
    ```
  
    Then, create a view that binds to your new controller:
  
    ```handlebars
    {{#each MyApp.listController as |person|}}
      {{person.firstName}} {{person.lastName}}
    {{/each}}
    ```
  
    Although you are binding to the controller, the behavior of this controller
    is to pass through any methods or properties to the underlying array. This
    capability comes from `Ember.ArrayProxy`, which this class inherits from.
  
    Sometimes you want to display computed properties within the body of an
    `#each` helper that depend on the underlying items in `model`, but are not
    present on those items.   To do this, set `itemController` to the name of a
    controller that will wrap each individual item.
  
    For example:
  
    ```handlebars
    {{#each controller as |post|}}
      <li>{{post.title}} ({{post.titleLength}} characters)</li>
    {{/each}}
    ```
  
    ```javascript
    App.PostsController = Ember.ArrayController.extend({
      itemController: 'post'
    });
  
    App.PostController = Ember.Controller.extend({
      // the `title` property will be proxied to the underlying post.
      titleLength: function() {
        return this.get('title').length;
      }.property('title')
    });
    ```
  
    In some cases it is helpful to return a different `itemController` depending
    on the particular item.  Subclasses can do this by overriding
    `lookupItemController`.
  
    For example:
  
    ```javascript
    App.MyArrayController = Ember.ArrayController.extend({
      lookupItemController: function( object ) {
        if (object.get('isSpecial')) {
          return "special"; // use App.SpecialController
        } else {
          return "regular"; // use App.RegularController
        }
      }
    });
    ```
  
    The itemController instances will have a `parentController` property set to
    the `ArrayController` instance.

      The `property` extension of Javascript's Function prototype is available
      when `Ember.EXTEND_PROTOTYPES` or `Ember.EXTEND_PROTOTYPES.Function` is
      `true`, which is the default.
       Computed properties allow you to treat a function like a property:
       ```javascript
      MyApp.President = Ember.Object.extend({
        firstName: '',
        lastName:  '',
         fullName: function() {
          return this.get('firstName') + ' ' + this.get('lastName');
        }.property() // Call this flag to mark the function as a property
      });
       var president = MyApp.President.create({
        firstName: 'Barack',
        lastName: 'Obama'
      });
       president.get('fullName'); // 'Barack Obama'
      ```
       Treating a function like a property is useful because they can work with
      bindings, just like any other property.
       Many computed properties have dependencies on other properties. For
      example, in the above example, the `fullName` property depends on
      `firstName` and `lastName` to determine its value. You can tell Ember
      about these dependencies like this:
       ```javascript
      MyApp.President = Ember.Object.extend({
        firstName: '',
        lastName:  '',
         fullName: function() {
          return this.get('firstName') + ' ' + this.get('lastName');
           // Tell Ember.js that this computed property depends on firstName
          // and lastName
        }.property('firstName', 'lastName')
      });
      ```
       Make sure you list these dependencies so Ember knows when to update
      bindings that connect to a computed property. Changing a dependency
      will not immediately trigger an update of the computed property, but
      will instead clear the cache so that it is updated when the next `get`
      is called on the property.
       See [Ember.ComputedProperty](/api/classes/Ember.ComputedProperty.html), [Ember.computed](/api/#method_computed).
       @method property
      @for Function

      var ret = _emberMetalComputed.computed(this);

    The `Ember.ActionHandler` mixin implements support for moving an `actions`
    property to an `_actions` property at extend time, and adding `_actions`
    to the object's mergedProperties list.
  
    `Ember.ActionHandler` is available on some familiar classes including
    `Ember.Route`, `Ember.View`, `Ember.Component`, and `Ember.Controller`.
    (Internally the mixin is used by `Ember.CoreView`, `Ember.ControllerMixin`,
    and `Ember.Route` and available to the above classes through
    inheritance.)
  
    @class ActionHandler

  var ActionHandler = _emberMetalMixin.Mixin.create({
    mergedProperties: ['_actions'],

    /**
      The collection of functions, keyed by name, available on this
      `ActionHandler` as action targets.
       These functions will be invoked when a matching `{{action}}` is triggered
      from within a template and the application's current route is this route.
       Actions can also be invoked from other parts of your application
      via `ActionHandler#send`.
       The `actions` hash will inherit action handlers from
      the `actions` hash defined on extended parent classes
      or mixins rather than just replace the entire hash, e.g.:
       ```js
      App.CanDisplayBanner = Ember.Mixin.create({
        actions: {
          displayBanner: function(msg) {
            // ...
          }
        }
      });
       App.WelcomeRoute = Ember.Route.extend(App.CanDisplayBanner, {
        actions: {
          playMusic: function() {
            // ...
          }
        }
      });
       // `WelcomeRoute`, when active, will be able to respond
      // to both actions, since the actions hash is merged rather
      // then replaced when extending mixins / parent classes.
      this.send('displayBanner');
      this.send('playMusic');
      ```
       Within a Controller, Route, View or Component's action handler,
      the value of the `this` context is the Controller, Route, View or
      Component object:
       ```js
      App.SongRoute = Ember.Route.extend({
        actions: {
          myAction: function() {
            this.controllerFor("song");
            this.transitionTo("other.route");
            ...
          }
        }
      });
      ```
       It is also possible to call `this._super.apply(this, arguments)` from within an
      action handler if it overrides a handler defined on a parent
      class or mixin:
       Take for example the following routes:
       ```js
      App.DebugRoute = Ember.Mixin.create({
        actions: {
          debugRouteInformation: function() {
            console.debug("trololo");
          }
        }
      });
       App.AnnoyingDebugRoute = Ember.Route.extend(App.DebugRoute, {
        actions: {
          debugRouteInformation: function() {
            // also call the debugRouteInformation of mixed in App.DebugRoute
            this._super.apply(this, arguments);
             // show additional annoyance
            window.alert(...);
          }
        }
      });
      ```
       ## Bubbling
       By default, an action will stop bubbling once a handler defined
      on the `actions` hash handles it. To continue bubbling the action,
      you must return `true` from the handler:
       ```js
      App.Router.map(function() {
        this.route("album", function() {
          this.route("song");
        });
      });
       App.AlbumRoute = Ember.Route.extend({
        actions: {
          startPlaying: function() {
          }
        }
      });
       App.AlbumSongRoute = Ember.Route.extend({
        actions: {
          startPlaying: function() {
            // ...
             if (actionShouldAlsoBeTriggeredOnParentRoute) {
              return true;
            }
          }
        }
      });

  /**
    This mixin implements Observer-friendly Array-like behavior. It is not a
    concrete implementation, but it can be used up by other classes that want
    to appear like arrays.
  
    For example, ArrayProxy and ArrayController are both concrete classes that can
    be instantiated to implement array-like behavior. Both of these classes use
    the Array Mixin by way of the MutableArray mixin, which allows observable
    changes to be made to the underlying array.
  
    Unlike `Ember.Enumerable,` this mixin defines methods specifically for
    collections that provide index-ordered access to their contents. When you
    are designing code that needs to accept any kind of Array-like object, you
    should use these methods instead of Array primitives because these will
    properly notify observers of changes to the array.
  
    Although these methods are efficient, they do add a layer of indirection to
    your application so it is a good idea to use them only when you need the
    flexibility of using both true JavaScript arrays and "virtual" arrays such
    as controllers and collections.
  
    You can use the methods defined in this module to access and modify array
    contents in a KVO-friendly way. You can also be notified whenever the
    membership of an array changes by using `.observes('myArray.[]')`.
  
    To support `Ember.Array` in your own class, you must override two
    primitives to use it: `replace()` and `objectAt()`.
  
    Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
    mixin. All `Ember.Array`-like objects are also enumerable.

  /**
    This mixin defines the common interface implemented by enumerable objects
    in Ember. Most of these methods follow the standard Array iteration
    API defined up to JavaScript 1.8 (excluding language-specific features that
    cannot be emulated in older versions of JavaScript).
  
    This mixin is applied automatically to the Array class on page load, so you
    can use any of these methods on simple arrays. If Array already implements
    one of these methods, the mixin will not override them.
  
    ## Writing Your Own Enumerable
  
    To make your own custom class enumerable, you need two items:
  
    1. You must have a length property. This property should change whenever
       the number of items in your enumerable object changes. If you use this
       with an `Ember.Object` subclass, you should be sure to change the length
       property using `set().`
  
    2. You must implement `nextObject().` See documentation.
  
    Once you have these two methods implemented, apply the `Ember.Enumerable` mixin
    to your class and you will be able to enumerate the contents of your object
    like any other collection.
  
    ## Using Ember Enumeration with Other Libraries
  
    Many other libraries provide some kind of iterator or enumeration like
    facility. This is often where the most common API conflicts occur.
    Ember's API is designed to be as friendly as possible with other
    libraries by implementing only methods that mostly correspond to the
    JavaScript 1.8 API.

  exports.default = _emberMetalMixin.Mixin.create({

    /**
      __Required.__ You must implement this method to apply this mixin.
       Implement this method to make your class enumerable.
       This method will be called repeatedly during enumeration. The index value
      will always begin with 0 and increment monotonically. You don't have to
      rely on the index value to determine what object to return, but you should
      always check the value and start from the beginning when you see the
      requested index is 0.
       The `previousObject` is the object that was returned from the last call
      to `nextObject` for the current iteration. This is a useful way to
      manage iteration if you are tracing a linked list, for example.
       Finally the context parameter will always contain a hash you can use as
      a "scratchpad" to maintain any other state you need in order to iterate
      properly. The context object is reused and is not reset between
      iterations so make sure you setup the context with a fresh state whenever
      the index parameter is 0.
       Generally iterators will continue to call `nextObject` until the index
      reaches the current length-1. If you run out of data before this
      time for some reason, you should simply return undefined.
       The default implementation of this method simply looks up the index.
      This works great on any Array-like objects.

  /**
    The `Ember.Freezable` mixin implements some basic methods for marking an
    object as frozen. Once an object is frozen it should be read only. No changes
    may be made the internal state of the object.
  
    ## Enforcement
  
    To fully support freezing in your subclass, you must include this mixin and
    override any method that might alter any property on the object to instead
    raise an exception. You can check the state of an object by checking the
    `isFrozen` property.
  
    Although future versions of JavaScript may support language-level freezing
    object objects, that is not the case today. Even if an object is freezable,
    it is still technically possible to modify the object, even though it could
    break other parts of your application that do not expect a frozen object to
    change. It is, therefore, very important that you always respect the
    `isFrozen` property on all freezable objects.
  
    ## Example Usage
  
    The example below shows a simple object that implement the `Ember.Freezable`
    protocol.
  
    ```javascript
    Contact = Ember.Object.extend(Ember.Freezable, {
      firstName: null,
      lastName: null,
  
      // swaps the names
      swapNames: function() {
        if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
        var tmp = this.get('firstName');
        this.set('firstName', this.get('lastName'));
        this.set('lastName', tmp);
        return this;
      }
  
    });
  
    c = Contact.create({ firstName: "John", lastName: "Doe" });
    c.swapNames();  // returns c
    c.freeze();
    c.swapNames();  // EXCEPTION
    ```
  
    ## Copying
  
    Usually the `Ember.Freezable` protocol is implemented in cooperation with the
    `Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
    return a frozen object, if the object implements this method as well.
  
    @class Freezable
    @namespace Ember
    @since Ember 0.9

    already present and is of a type supported by the enumerable.
  
    ```javascript
    set.addObject(contact);
    ```
  
    ## Removing Objects
  
    To remove an object from an enumerable, use the `removeObject()` method. This
    will only remove the object if it is present in the enumerable, otherwise
    this method has no effect.
  
    ```javascript
    set.removeObject(contact);
    ```
  
    ## Implementing In Your Own Code
  
    If you are implementing an object and want to support this API, just include
    this mixin in your class and implement the required methods. In your unit
    tests, be sure to apply the Ember.MutableEnumerableTests to your object.

  /**
    ## Overview
  
    This mixin provides properties and property observing functionality, core
    features of the Ember object model.
  
    Properties and observers allow one object to observe changes to a
    property on another object. This is one of the fundamental ways that
    models, controllers and views communicate with each other in an Ember
    application.
  
    Any object that has this mixin applied can be used in observer
    operations. That includes `Ember.Object` and most objects you will
    interact with as you write your Ember application.
  
    Note that you will not generally apply this mixin to classes yourself,
    but you will use the features provided by this module frequently, so it
    is important to understand how to use it.
  
    ## Using `get()` and `set()`
  
    Because of Ember's support for bindings and observers, you will always
    access properties using the get method, and set properties using the
    set method. This allows the observing objects to be notified and
    computed properties to be handled properly.
  
    More documentation about `get` and `set` are below.
  
    ## Observing Property Changes
  
    You typically observe property changes simply by adding the `observes`
    call to the end of your method declarations in classes that you write.
    For example:
  
    ```javascript
    Ember.Object.extend({
      valueObserver: function() {
        // Executes whenever the "value" property changes
      }.observes('value')
    });
    ```
  
    Although this is the most common way to add an observer, this capability
    is actually built into the `Ember.Object` class on top of two methods
    defined in this mixin: `addObserver` and `removeObserver`. You can use
    these two methods to add and remove observers yourself if you need to
    do so at runtime.
  
    To add an observer for a property, call:
  
    ```javascript
    object.addObserver('propertyKey', targetObject, targetAction)
    ```
  
    This will call the `targetAction` method on the `targetObject` whenever
    the value of the `propertyKey` changes.
  
    Note that if `propertyKey` is a computed property, the observer will be
    called when any of the property dependencies are changed, even if the
    resulting value of the computed property is unchanged. This is necessary
    because computed properties are not computed until `get` is called.
  
    @class Observable
    @namespace Ember
    @public
  */
  exports.default = _emberMetalMixin.Mixin.create({

    /**
      Retrieves the value of a property from the object.
       This method is usually similar to using `object[keyName]` or `object.keyName`,
      however it supports both computed properties and the unknownProperty
      handler.
       Because `get` unifies the syntax for accessing all these kinds
      of properties, it can make many refactorings easier, such as replacing a
      simple property with a computed property, or vice versa.
       ### Computed Properties
       Computed properties are methods defined with the `property` modifier
      declared at the end, such as:
       ```javascript
      fullName: function() {
        return this.get('firstName') + ' ' + this.get('lastName');
      }.property('firstName', 'lastName')
      ```
       When you call `get` on a computed property, the function will be
      called and the return value will be returned instead of the function
      itself.
       ### Unknown Properties
       Likewise, if you try to call `get` on a property whose value is
      `undefined`, the `unknownProperty()` method will be called on the object.
      If this method returns any value other than `undefined`, it will be returned
      instead. This allows you to implement "virtual" properties that are
      not defined upfront.
       @method get
      @param {String} keyName The property to retrieve
      @return {Object} The property value or undefined.
      @public
    */
    get: function (keyName) {
      return _emberMetalProperty_get.get(this, keyName);
    },

    /**
      To get the values of multiple properties at once, call `getProperties`
      with a list of strings or an array:
       ```javascript
      record.getProperties('firstName', 'lastName', 'zipCode');
      // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
      ```
       is equivalent to:
       ```javascript
      record.getProperties(['firstName', 'lastName', 'zipCode']);
      // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
      ```
       @method getProperties
      @param {String...|Array} list of keys to get
      @return {Object}
      @public
    */
    getProperties: function () {
      for (var _len = arguments.length, args = Array(_len), _key = 0; _key < _len; _key++) {
        args[_key] = arguments[_key];
      }

      return _emberMetalGet_properties.default.apply(null, [this].concat(args));
    },

    /**
      Sets the provided key or path to the value.
       This method is generally very similar to calling `object[key] = value` or
      `object.key = value`, except that it provides support for computed
      properties, the `setUnknownProperty()` method and property observers.
       ### Computed Properties
       If you try to set a value on a key that has a computed property handler
      defined (see the `get()` method for an example), then `set()` will call
      that method, passing both the value and key instead of simply changing
      the value itself. This is useful for those times when you need to
      implement a property that is composed of one or more member
      properties.
       ### Unknown Properties
       If you try to set a value on a key that is undefined in the target
      object, then the `setUnknownProperty()` handler will be called instead. This
      gives you an opportunity to implement complex "virtual" properties that
      are not predefined on the object. If `setUnknownProperty()` returns
      undefined, then `set()` will simply set the value on the object.
       ### Property Observers
       In addition to changing the property, `set()` will also register a property
      change with the object. Unless you have placed this call inside of a
      `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
      (i.e. observer methods declared on the same object), will be called
      immediately. Any "remote" observers (i.e. observer methods declared on
      another object) will be placed in a queue and called at a later time in a
      coalesced manner.
       @method set
      @param {String} keyName The property to set
      @param {Object} value The value to set or `null`.
      @return {Object} The passed value
      @public
    */

    },

    /**
      Sets a list of properties at once. These properties are set inside
      a single `beginPropertyChanges` and `endPropertyChanges` batch, so
      observers will be buffered.
       ```javascript
      record.setProperties({ firstName: 'Charles', lastName: 'Jolley' });
      ```
       @method setProperties
      @param {Object} hash the hash of keys and values to set

    /**
      Adds an observer on a property.
       This is the core method used to register an observer for a property.
       Once you call this method, any time the key's value is set, your observer
      will be notified. Note that the observers are triggered any time the
      value is set, regardless of whether it has actually changed. Your
      observer should be prepared to handle that.
       You can also pass an optional context parameter to this method. The
      context will be passed to your observer method whenever it is triggered.
      Note that if you add the same target/method pair on a key multiple times
      with different context parameters, your observer will only be called once
      with the last context you passed.
       ### Observer Methods
       Observer methods you pass should generally have the following signature if
      you do not pass a `context` parameter:
       ```javascript
      fooDidChange: function(sender, key, value, rev) { };
      ```
       The sender is the object that changed. The key is the property that
      changes. The value property is currently reserved and unused. The rev
      is the last property revision of the object when it changed, which you can
      use to detect if the key value has really changed or not.
       If you pass a `context` parameter, the context will be passed before the
      revision like so:
       ```javascript
      fooDidChange: function(sender, key, value, context, rev) { };
      ```
       Usually you will not need the value, context or revision parameters at
      the end. In this case, it is common to write observer methods that take
      only a sender and key value as parameters or, if you aren't interested in
      any of these values, to write an observer that has no parameters at all.
       @method addObserver

  /**
    `Ember.SortableMixin` provides a standard interface for array proxies
    to specify a sort order and maintain this sorting when objects are added,
    removed, or updated without changing the implicit order of their underlying
    model array:
  
    ```javascript
    songs = [
      {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'},
      {trackNumber: 2, title: 'Back in the U.S.S.R.'},
      {trackNumber: 3, title: 'Glass Onion'},
    ];
  
    songsController = Ember.ArrayController.create({
      model: songs,
      sortProperties: ['trackNumber'],
      sortAscending: true
    });
  
    songsController.get('firstObject');  // {trackNumber: 2, title: 'Back in the U.S.S.R.'}
  
    songsController.addObject({trackNumber: 1, title: 'Dear Prudence'});
    songsController.get('firstObject');  // {trackNumber: 1, title: 'Dear Prudence'}
    ```
  
    If you add or remove the properties to sort by or change the sort direction the model
    sort order will be automatically updated.
  
    ```javascript
    songsController.set('sortProperties', ['title']);
    songsController.get('firstObject'); // {trackNumber: 2, title: 'Back in the U.S.S.R.'}
  
    songsController.toggleProperty('sortAscending');
    songsController.get('firstObject'); // {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'}
    ```
  
    `SortableMixin` works by sorting the `arrangedContent` array, which is the array that
    `ArrayProxy` displays. Due to the fact that the underlying 'content' array is not changed, that
    array will not display the sorted list:
  
     ```javascript
    songsController.get('content').get('firstObject'); // Returns the unsorted original content
    songsController.get('firstObject'); // Returns the sorted content.
    ```
  
    Although the sorted content can also be accessed through the `arrangedContent` property,
    it is preferable to use the proxied class and not the `arrangedContent` array directly.

    out the underlying array is useful.

    ```

      `init` declaration! If you don't, Ember may not have an opportunity to
      do important setup work, and you'll see strange behavior in your
      application.

    /**
      Defines the properties that will be concatenated from the superclass
      (instead of overridden).
       By default, when you extend an Ember class a property defined in
      the subclass overrides a property with the same name that is defined
      in the superclass. However, there are some cases where it is preferable
      to build up a property's value by combining the superclass' property
      value with the subclass' value. An example of this in use within Ember
      is the `classNames` property of `Ember.View`.
       Here is some sample code showing the difference between a concatenated
      property and a normal one:
       ```javascript
      App.BarView = Ember.View.extend({
        someNonConcatenatedProperty: ['bar'],
        classNames: ['bar']
      });
       App.FooBarView = App.BarView.extend({
        someNonConcatenatedProperty: ['foo'],
        classNames: ['foo']
      });
       var fooBarView = App.FooBarView.create();
      fooBarView.get('someNonConcatenatedProperty'); // ['foo']
      fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
      ```
       This behavior extends to object creation as well. Continuing the
      above example:
       ```javascript
      var view = App.FooBarView.create({
        someNonConcatenatedProperty: ['baz'],
        classNames: ['baz']
      })
      view.get('someNonConcatenatedProperty'); // ['baz']
      view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
      ```
      Adding a single property that is not an array will just add it in the array:
       ```javascript
      var view = App.FooBarView.create({
        classNames: 'baz'
      })
      view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
      ```
       Using the `concatenatedProperties` property, we can tell Ember to mix the
      content of the properties.
       In `Ember.View` the `classNameBindings` and `attributeBindings` properties
      are also concatenated, in addition to `classNames`.
       This feature is available for you to use throughout the Ember object model,
      although typical app developers are likely to use it infrequently. Since
      it changes expectations about behavior of properties, you should properly
      document its usage in each individual concatenated property (to not
      mislead your users to think they can override the property in a subclass).

      @type Array

      Creates a new subclass.
       ```javascript
      App.Person = Ember.Object.extend({
        say: function(thing) {
          alert(thing);
         }
      });
      ```
       This defines a new subclass of Ember.Object: `App.Person`. It contains one method: `say()`.
       You can also create a subclass from any existing class by calling its `extend()`  method. For example, you might want to create a subclass of Ember's built-in `Ember.View` class:
       ```javascript
      App.PersonView = Ember.View.extend({
        tagName: 'li',
        classNameBindings: ['isAdministrator']
      });
      ```
       When defining a subclass, you can override methods but still access the implementation of your parent class by calling the special `_super()` method:
       ```javascript
      App.Person = Ember.Object.extend({
        say: function(thing) {
          var name = this.get('name');
          alert(name + ' says: ' + thing);
        }
      });
       App.Soldier = App.Person.extend({
        say: function(thing) {
          this._super(thing + ", sir!");
        },
        march: function(numberOfHours) {
          alert(this.get('name') + ' marches for ' + numberOfHours + ' hours.')
        }
      });
       var yehuda = App.Soldier.create({
        name: "Yehuda Katz"
      });
       yehuda.say("Yes");  // alerts "Yehuda Katz says: Yes, sir!"
      ```
       The `create()` on line #17 creates an *instance* of the `App.Soldier` class. The `extend()` on line #8 creates a *subclass* of `App.Person`. Any instance of the `App.Person` class will *not* have the `march()` method.
       You can also pass `Mixin` classes to add additional properties to the subclass.
       ```javascript
      App.Person = Ember.Object.extend({
        say: function(thing) {
          alert(this.get('name') + ' says: ' + thing);
        }
      });
       App.SingingMixin = Mixin.create({
        sing: function(thing){
          alert(this.get('name') + ' sings: la la la ' + thing);
        }
      });
       App.BroadwayStar = App.Person.extend(App.SingingMixin, {
        dance: function() {
          alert(this.get('name') + ' dances: tap tap tap tap ');
        }
      });
      ```
       The `App.BroadwayStar` class contains three methods: `say()`, `sing()`, and `dance()`.

    `TextSupport` is a shared mixin used by both `Ember.TextField` and
    `Ember.TextArea`. `TextSupport` adds a number of methods that allow you to
    specify a controller action to invoke when a certain event is fired on your
    text field or textarea. The specifed controller action would get the current
    value of the field passed in as the only argument unless the value of
    the field is empty. In that case, the instance of the field itself is passed
    in as the only argument.
  
    Let's use the pressing of the escape key as an example. If you wanted to
    invoke a controller action when a user presses the escape key while on your
    field, you would use the `escape-press` attribute on your field like so:
  
    ```handlebars
      {{! application.hbs}}
  
      {{input escape-press='alertUser'}}
    ```
  
    ```javascript
        App = Ember.Application.create();
  
        App.ApplicationController = Ember.Controller.extend({
          actions: {
            alertUser: function ( currentValue ) {
              alert( 'escape pressed, current value: ' + currentValue );
            }
          }
        });
    ```
  
    The following chart is a visual representation of what takes place when the
    escape key is pressed in this scenario:
  
    ```

    Here are the events that we currently support along with the name of the
    attribute you would need to use on your field. To reiterate, you would use the
    attribute name like so:
  
    ```handlebars
      {{input attribute-name='controllerAction'}}

  /**
  `Ember.ViewTargetActionSupport` is a mixin that can be included in a
  view class to add a `triggerAction` method with semantics similar to
  the Handlebars `{{action}}` helper. It provides intelligent defaults
  for the action's target: the view's controller; and the context that is
  sent with the action: the view's context.
  
  Note: In normal Ember usage, the `{{action}}` helper is usually the best
  choice. This mixin is most often useful when you are doing more complex
  event handling in custom View subclasses.
  
  For example:
  
  ```javascript
  App.SaveButtonView = Ember.View.extend(Ember.ViewTargetActionSupport, {
    action: 'save',
    click: function() {
      this.triggerAction(); // Sends the `save` action, along with the current context
                            // to the current controller
    }
  });
  ```
  
  The `action` can be provided as properties of an optional object argument
  to `triggerAction` as well.
  
  ```javascript
  App.SaveButtonView = Ember.View.extend(Ember.ViewTargetActionSupport, {
    click: function() {
      this.triggerAction({
        action: 'save'
      }); // Sends the `save` action, along with the current context
          // to the current controller
    }
  });

    `Ember.CollectionView` is an `Ember.View` descendent responsible for managing
    a collection (an array or array-like object) by maintaining a child view object
    and associated DOM representation for each item in the array and ensuring
    that child views and their associated rendered HTML are updated when items in
    the array are added, removed, or replaced.
  
    ## Setting content
  
    The managed collection of objects is referenced as the `Ember.CollectionView`
    instance's `content` property.
  
    ```javascript
    someItemsView = Ember.CollectionView.create({
      content: ['A', 'B','C']
    })
    ```
  
    The view for each item in the collection will have its `content` property set
    to the item.
  
    ## Specifying `itemViewClass`
  
    By default the view class for each item in the managed collection will be an
    instance of `Ember.View`. You can supply a different class by setting the
    `CollectionView`'s `itemViewClass` property.
  
    Given the following application code:
  
    ```javascript
    var App = Ember.Application.create();
    App.ItemListView = Ember.CollectionView.extend({
      classNames: ['a-collection'],
      content: ['A','B','C'],
      itemViewClass: Ember.View.extend({
        template: Ember.HTMLBars.compile("the letter: {{view.content}}")
      })
    });
    ```
  
    And a simple application template:
  
    ```handlebars
    {{view 'item-list'}}
    ```
  
    The following HTML will result:
  
    ```html
    <div class="ember-view a-collection">
      <div class="ember-view">the letter: A</div>
      <div class="ember-view">the letter: B</div>
      <div class="ember-view">the letter: C</div>
    </div>
    ```
  
    ## Automatic matching of parent/child tagNames
  
    Setting the `tagName` property of a `CollectionView` to any of
    "ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
    in the item views receiving an appropriately matched `tagName` property.
  
    Given the following application code:
  
    ```javascript
    var App = Ember.Application.create();
    App.UnorderedListView = Ember.CollectionView.create({
      tagName: 'ul',
      content: ['A','B','C'],
      itemViewClass: Ember.View.extend({
        template: Ember.HTMLBars.compile("the letter: {{view.content}}")
      })
    });
    ```
  
    And a simple application template:
  
    ```handlebars
    {{view 'unordered-list-view'}}
    ```
  
    The following HTML will result:
  
    ```html
    <ul class="ember-view a-collection">
      <li class="ember-view">the letter: A</li>
      <li class="ember-view">the letter: B</li>
      <li class="ember-view">the letter: C</li>
    </ul>
    ```
  
    Additional `tagName` pairs can be provided by adding to
    `Ember.CollectionView.CONTAINER_MAP`. For example:
  
    ```javascript
    Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
    ```
  
    ## Programmatic creation of child views
  
    For cases where additional customization beyond the use of a single
    `itemViewClass` or `tagName` matching is required CollectionView's
    `createChildView` method can be overridden:
  
    ```javascript
    App.CustomCollectionView = Ember.CollectionView.extend({
      createChildView: function(viewClass, attrs) {
        if (attrs.content.kind == 'album') {
          viewClass = App.AlbumView;
        } else {
          viewClass = App.SongView;
        }
        return this._super(viewClass, attrs);
      }
    });
    ```
  
    ## Empty View
  
    You can provide an `Ember.View` subclass to the `Ember.CollectionView`
    instance as its `emptyView` property. If the `content` property of a
    `CollectionView` is set to `null` or an empty array, an instance of this view
    will be the `CollectionView`s only child.
  
    ```javascript
    var App = Ember.Application.create();
    App.ListWithNothing = Ember.CollectionView.create({
      classNames: ['nothing'],
      content: null,
      emptyView: Ember.View.extend({
        template: Ember.HTMLBars.compile("The collection is empty")
      })
    });
    ```
  
    And a simple application template:
  
    ```handlebars
    {{view 'list-with-nothing'}}
    ```
  
    The following HTML will result:
  
    ```html
    <div class="ember-view nothing">
      <div class="ember-view">
        The collection is empty
      </div>
    </div>
    ```
  
    ## Adding and Removing items
  
    The `childViews` property of a `CollectionView` should not be directly
    manipulated. Instead, add, remove, replace items from its `content` property.
    This will trigger appropriate changes to its rendered HTML.

  /**
    An `Ember.Component` is a view that is completely
    isolated. Properties accessed in its templates go
    to the view object and actions are targeted at
    the view object. There is no access to the
    surrounding context or outer controller; all
    contextual information must be passed in.
  
    The easiest way to create an `Ember.Component` is via
    a template. If you name a template
    `components/my-foo`, you will be able to use
    `{{my-foo}}` in other templates, which will make
    an instance of the isolated component.
  
    ```handlebars
    {{app-profile person=currentUser}}
    ```
  
    ```handlebars
    <!-- app-profile template -->
    <h1>{{person.title}}</h1>
    <img src={{person.avatar}}>
    <p class='signature'>{{person.signature}}</p>
    ```
  
    You can use `yield` inside a template to
    include the **contents** of any block attached to
    the component. The block will be executed in the
    context of the surrounding context or outer controller:
  
    ```handlebars
    {{#app-profile person=currentUser}}
      <p>Admin mode</p>
      {{! Executed in the controller's context. }}
    {{/app-profile}}
    ```
  
    ```handlebars
    <!-- app-profile template -->
    <h1>{{person.title}}</h1>
    {{! Executed in the components context. }}
    {{yield}} {{! block contents }}
    ```
  
    If you want to customize the component, in order to
    handle events or actions, you implement a subclass
    of `Ember.Component` named after the name of the
    component. Note that `Component` needs to be appended to the name of
    your subclass like `AppProfileComponent`.
  
    For example, you could implement the action
    `hello` for the `app-profile` component:
  
    ```javascript
    App.AppProfileComponent = Ember.Component.extend({
      actions: {
        hello: function(name) {
          console.log("Hello", name);
        }
      }
    });
    ```
  
    And then use it in the component's template:
  
    ```handlebars
    <!-- app-profile template -->
  
    <h1>{{person.title}}</h1>
    {{yield}} <!-- block contents -->
  
    <button {{action 'hello' person.name}}>
      Say Hello to {{person.name}}
    </button>
    ```
  
    Components must have a `-` in their name to avoid
    conflicts with built-in controls that wrap HTML
    elements. This is consistent with the same
    requirement in web components.

      of the component:
        ```javascript

            this.sendAction('stop');
          }
        }
      });
      ```

      trigger actions in the outer application context:
       ```handlebars
      {{! application.hbs }}
      {{play-button play="musicStarted" stop="musicStopped"}}
      ```
       When the component receives a browser `click` event it translate this
      interaction into application-specific semantics ("play" or "stop") and
      triggers the specified action name on the controller for the template
      where the component is used:
        ```javascript
      App.ApplicationController = Ember.Controller.extend({
        actions: {
          musicStarted: function() {
            // called when the play button is clicked
            // and the music started playing
          },
          musicStopped: function() {
            // called when the play button is clicked
            // and the music stopped playing
          }
        }
      });
      ```
       If no action name is passed to `sendAction` a default name of "action"
      is assumed.

  /**
    A `ContainerView` is an `Ember.View` subclass that implements `Ember.MutableArray`
    allowing programmatic management of its child views.
  
    ## Setting Initial Child Views
  
    The initial array of child views can be set in one of two ways. You can
    provide a `childViews` property at creation time that contains instance of
    `Ember.View`:
  
    ```javascript
    aContainer = Ember.ContainerView.create({
      childViews: [Ember.View.create(), Ember.View.create()]
    });
    ```
  
    You can also provide a list of property names whose values are instances of
    `Ember.View`:
  
    ```javascript
    aContainer = Ember.ContainerView.create({
      childViews: ['aView', 'bView', 'cView'],
      aView: Ember.View.create(),
      bView: Ember.View.create(),
      cView: Ember.View.create()
    });
    ```
  
    The two strategies can be combined:
  
    ```javascript
    aContainer = Ember.ContainerView.create({
      childViews: ['aView', Ember.View.create()],
      aView: Ember.View.create()
    });
    ```
  
    Each child view's rendering will be inserted into the container's rendered
    HTML in the same order as its position in the `childViews` property.
  
    ## Adding and Removing Child Views
  
    The container view implements `Ember.MutableArray` allowing programmatic management of its child views.
  
    To remove a view, pass that view into a `removeObject` call on the container view.
  
    Given an empty `<body>` the following code
  
    ```javascript
    aContainer = Ember.ContainerView.create({
      classNames: ['the-container'],
      childViews: ['aView', 'bView'],
      aView: Ember.View.create({
        template: Ember.HTMLBars.compile("A")
      }),
      bView: Ember.View.create({
        template: Ember.HTMLBars.compile("B")
      })
    });
  
    aContainer.appendTo('body');
    ```
  
    Results in the HTML
  
    ```html
    <div class="ember-view the-container">
      <div class="ember-view">A</div>
      <div class="ember-view">B</div>
    </div>
    ```
  
    Removing a view
  
    ```javascript
    aContainer.toArray();  // [aContainer.aView, aContainer.bView]
    aContainer.removeObject(aContainer.get('bView'));
    aContainer.toArray();  // [aContainer.aView]
    ```
  
    Will result in the following HTML
  
    ```html
    <div class="ember-view the-container">
      <div class="ember-view">A</div>
    </div>
    ```
  
    Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
    container view.
  
    Given an empty `<body>` the following code
  
    ```javascript
    aContainer = Ember.ContainerView.create({
      classNames: ['the-container'],
      childViews: ['aView', 'bView'],
      aView: Ember.View.create({
        template: Ember.HTMLBars.compile("A")
      }),
      bView: Ember.View.create({
        template: Ember.HTMLBars.compile("B")
      })
    });
  
    aContainer.appendTo('body');
    ```
  
    Results in the HTML
  
    ```html
    <div class="ember-view the-container">
      <div class="ember-view">A</div>
      <div class="ember-view">B</div>
    </div>
    ```
  
    Adding a view
  
    ```javascript
    AnotherViewClass = Ember.View.extend({
      template: Ember.HTMLBars.compile("Another view")
    });
  
    aContainer.toArray();  // [aContainer.aView, aContainer.bView]
    aContainer.pushObject(AnotherViewClass.create());
    aContainer.toArray(); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
    ```
  
    Will result in the following HTML
  
    ```html
    <div class="ember-view the-container">
      <div class="ember-view">A</div>
      <div class="ember-view">B</div>
      <div class="ember-view">Another view</div>
    </div>
    ```
  
    ## Templates and Layout
  
    A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or
    `defaultLayout` property on a container view will not result in the template
    or layout being rendered. The HTML contents of a `Ember.ContainerView`'s DOM
    representation will only be the rendered HTML of its child views.

  /**
    The `Ember.Select` view class renders a
    [select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
    allowing the user to choose from a list of options.
  
    The text and `value` property of each `<option>` element within the
    `<select>` element are populated from the objects in the `Element.Select`'s
    `content` property. The underlying data object of the selected `<option>` is
    stored in the `Element.Select`'s `value` property.
  
    ## The Content Property (array of strings)
  
    The simplest version of an `Ember.Select` takes an array of strings as its
    `content` property. The string will be used as both the `value` property and
    the inner text of each `<option>` element inside the rendered `<select>`.
  
    Example:
  
    ```javascript
    App.ApplicationController = Ember.Controller.extend({
      names: ["Yehuda", "Tom"]
    });
    ```
  
    ```handlebars
    {{view "select" content=names}}
    ```
  
    Would result in the following HTML:
  
    ```html
    <select class="ember-select">
      <option value="Yehuda">Yehuda</option>
      <option value="Tom">Tom</option>
    </select>
    ```
  
    You can control which `<option>` is selected through the `Ember.Select`'s
    `value` property:
  
    ```javascript
    App.ApplicationController = Ember.Controller.extend({
      selectedName: 'Tom',
      names: ["Yehuda", "Tom"]
    });
    ```
  
    ```handlebars
    {{view "select" content=names value=selectedName}}
    ```
  
    Would result in the following HTML with the `<option>` for 'Tom' selected:
  
    ```html
    <select class="ember-select">
      <option value="Yehuda">Yehuda</option>
      <option value="Tom" selected="selected">Tom</option>
    </select>
    ```
  
    A user interacting with the rendered `<select>` to choose "Yehuda" would
    update the value of `selectedName` to "Yehuda".
  
    ## The Content Property (array of Objects)
  
    An `Ember.Select` can also take an array of JavaScript or Ember objects as
    its `content` property.
  
    When using objects you need to tell the `Ember.Select` which property should
    be accessed on each object to supply the `value` attribute of the `<option>`
    and which property should be used to supply the element text.
  
    The `optionValuePath` option is used to specify the path on each object to
    the desired property for the `value` attribute. The `optionLabelPath`
    specifies the path on each object to the desired property for the
    element's text. Both paths must reference each object itself as `content`:
  
    ```javascript
    App.ApplicationController = Ember.Controller.extend({
      programmers: [
        {firstName: "Yehuda", id: 1},
        {firstName: "Tom",    id: 2}
      ]
    });
    ```
  
    ```handlebars
    {{view "select"
           content=programmers
           optionValuePath="content.id"
           optionLabelPath="content.firstName"}}
    ```
  
    Would result in the following HTML:
  
    ```html
    <select class="ember-select">
      <option value="1">Yehuda</option>
      <option value="2">Tom</option>
    </select>
    ```
  
    The `value` attribute of the selected `<option>` within an `Ember.Select`
    can be bound to a property on another object:
  
    ```javascript
    App.ApplicationController = Ember.Controller.extend({
      programmers: [
        {firstName: "Yehuda", id: 1},
        {firstName: "Tom",    id: 2}
      ],
      currentProgrammer: {
        id: 2
      }
    });
    ```
  
    ```handlebars
    {{view "select"
           content=programmers
           optionValuePath="content.id"
           optionLabelPath="content.firstName"
           value=currentProgrammer.id}}
    ```
  
    Would result in the following HTML with a selected option:
  
    ```html
    <select class="ember-select">
      <option value="1">Yehuda</option>
      <option value="2" selected="selected">Tom</option>
    </select>
    ```
  
    Interacting with the rendered element by selecting the first option
    ('Yehuda') will update the `id` of `currentProgrammer`
    to match the `value` property of the newly selected `<option>`.
  
    Alternatively, you can control selection through the underlying objects
    used to render each object by binding the `selection` option. When the selected
    `<option>` is changed, the property path provided to `selection`
    will be updated to match the content object of the rendered `<option>`
    element:
  
    ```javascript
  
    var yehuda = {firstName: "Yehuda", id: 1, bff4eva: 'tom'}
    var tom = {firstName: "Tom", id: 2, bff4eva: 'yehuda'};
  
    App.ApplicationController = Ember.Controller.extend({
      selectedPerson: tom,
      programmers: [ yehuda, tom ]
    });
    ```
  
    ```handlebars
    {{view "select"
           content=programmers
           optionValuePath="content.id"
           optionLabelPath="content.firstName"
           selection=selectedPerson}}
    ```
  
    Would result in the following HTML with a selected option:
  
    ```html
    <select class="ember-select">
      <option value="1">Yehuda</option>
      <option value="2" selected="selected">Tom</option>
    </select>
    ```
  
    Interacting with the rendered element by selecting the first option
    ('Yehuda') will update the `selectedPerson` to match the object of
    the newly selected `<option>`. In this case it is the first object
    in the `programmers`
  
    ## Supplying a Prompt
  
    A `null` value for the `Ember.Select`'s `value` or `selection` property
    results in there being no `<option>` with a `selected` attribute:
  
    ```javascript
    App.ApplicationController = Ember.Controller.extend({
      selectedProgrammer: null,
      programmers: ["Yehuda", "Tom"]
    });
    ```
  
    ``` handlebars
    {{view "select"
           content=programmers
           value=selectedProgrammer
    }}
    ```
  
    Would result in the following HTML:
  
    ```html
    <select class="ember-select">
      <option value="Yehuda">Yehuda</option>
      <option value="Tom">Tom</option>
    </select>
    ```
  
    Although `selectedProgrammer` is `null` and no `<option>`
    has a `selected` attribute the rendered HTML will display the
    first item as though it were selected. You can supply a string
    value for the `Ember.Select` to display when there is no selection
    with the `prompt` option:
  
    ```javascript
    App.ApplicationController = Ember.Controller.extend({
      selectedProgrammer: null,
      programmers: [ "Yehuda", "Tom" ]
    });
    ```
  
    ```handlebars
    {{view "select"
           content=programmers
           value=selectedProgrammer
           prompt="Please select a name"
    }}
    ```
  
    Would result in the following HTML:
  
    ```html
    <select class="ember-select">
      <option>Please select a name</option>
      <option value="Yehuda">Yehuda</option>
      <option value="Tom">Tom</option>
    </select>
    ```

  /**
    `Ember.View` is the class in Ember responsible for encapsulating templates of
    HTML content, combining templates with data to render as sections of a page's
    DOM, and registering and responding to user-initiated events.
  
    ## HTML Tag
  
    The default HTML tag name used for a view's DOM representation is `div`. This
    can be customized by setting the `tagName` property. The following view
    class:
  
    ```javascript
    ParagraphView = Ember.View.extend({
      tagName: 'em'
    });
    ```
  
    Would result in instances with the following HTML:
  
    ```html
    <em id="ember1" class="ember-view"></em>
    ```
  
    ## HTML `class` Attribute
  
    The HTML `class` attribute of a view's tag can be set by providing a
    `classNames` property that is set to an array of strings:
  
    ```javascript
    MyView = Ember.View.extend({
      classNames: ['my-class', 'my-other-class']
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view my-class my-other-class"></div>
    ```
  
    `class` attribute values can also be set by providing a `classNameBindings`
    property set to an array of properties names for the view. The return value
    of these properties will be added as part of the value for the view's `class`
    attribute. These properties can be computed properties:
  
    ```javascript
    MyView = Ember.View.extend({
      classNameBindings: ['propertyA', 'propertyB'],
      propertyA: 'from-a',
      propertyB: Ember.computed(function() {
        if (someLogic) { return 'from-b'; }
      })
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view from-a from-b"></div>
    ```
  
    If the value of a class name binding returns a boolean the property name
    itself will be used as the class name if the property is true. The class name
    will not be added if the value is `false` or `undefined`.
  
    ```javascript
    MyView = Ember.View.extend({
      classNameBindings: ['hovered'],
      hovered: true
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view hovered"></div>
    ```
  
    When using boolean class name bindings you can supply a string value other
    than the property name for use as the `class` HTML attribute by appending the
    preferred value after a ":" character when defining the binding:
  
    ```javascript
    MyView = Ember.View.extend({
      classNameBindings: ['awesome:so-very-cool'],
      awesome: true
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view so-very-cool"></div>
    ```
  
    Boolean value class name bindings whose property names are in a
    camelCase-style format will be converted to a dasherized format:
  
    ```javascript
    MyView = Ember.View.extend({
      classNameBindings: ['isUrgent'],
      isUrgent: true
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view is-urgent"></div>
    ```
  
    Class name bindings can also refer to object values that are found by
    traversing a path relative to the view itself:
  
    ```javascript
    MyView = Ember.View.extend({
      classNameBindings: ['messages.empty']
      messages: Ember.Object.create({
        empty: true
      })
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view empty"></div>
    ```
  
    If you want to add a class name for a property which evaluates to true and
    and a different class name if it evaluates to false, you can pass a binding
    like this:
  
    ```javascript
    // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
    Ember.View.extend({
      classNameBindings: ['isEnabled:enabled:disabled']
      isEnabled: true
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view enabled"></div>
    ```
  
    When isEnabled is `false`, the resulting HTML representation looks like
    this:
  
    ```html
    <div id="ember1" class="ember-view disabled"></div>
    ```
  
    This syntax offers the convenience to add a class if a property is `false`:
  
    ```javascript
    // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
    Ember.View.extend({
      classNameBindings: ['isEnabled::disabled']
      isEnabled: true
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view"></div>
    ```
  
    When the `isEnabled` property on the view is set to `false`, it will result
    in view instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view disabled"></div>
    ```
  
    Updates to the the value of a class name binding will result in automatic
    update of the  HTML `class` attribute in the view's rendered HTML
    representation. If the value becomes `false` or `undefined` the class name
    will be removed.
  
    Both `classNames` and `classNameBindings` are concatenated properties. See
    [Ember.Object](/api/classes/Ember.Object.html) documentation for more
    information about concatenated properties.
  
    ## HTML Attributes
  
    The HTML attribute section of a view's tag can be set by providing an
    `attributeBindings` property set to an array of property names on the view.
    The return value of these properties will be used as the value of the view's
    HTML associated attribute:
  
    ```javascript
    AnchorView = Ember.View.extend({
      tagName: 'a',
      attributeBindings: ['href'],
      href: 'http://google.com'
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <a id="ember1" class="ember-view" href="http://google.com"></a>
    ```
  
    One property can be mapped on to another by placing a ":" between
    the source property and the destination property:
  
    ```javascript
    AnchorView = Ember.View.extend({
      tagName: 'a',
      attributeBindings: ['url:href'],
      url: 'http://google.com'
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <a id="ember1" class="ember-view" href="http://google.com"></a>
    ```
  
    Namespaced attributes (e.g. `xlink:href`) are supported, but have to be
    mapped, since `:` is not a valid character for properties in Javascript:
  
    ```javascript
    UseView = Ember.View.extend({
      tagName: 'use',
      attributeBindings: ['xlinkHref:xlink:href'],
      xlinkHref: '#triangle'
    });
    ```
    Will result in view instances with an HTML representation of:
  
    ```html
    <use xlink:href="#triangle"></use>
    ```
  
    If the return value of an `attributeBindings` monitored property is a boolean
    the property will follow HTML's pattern of repeating the attribute's name as
    its value:
  
    ```javascript
    MyTextInput = Ember.View.extend({
      tagName: 'input',
      attributeBindings: ['disabled'],
      disabled: true
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <input id="ember1" class="ember-view" disabled="disabled" />
    ```
  
    `attributeBindings` can refer to computed properties:
  
    ```javascript
    MyTextInput = Ember.View.extend({
      tagName: 'input',
      attributeBindings: ['disabled'],
      disabled: Ember.computed(function() {
        if (someLogic) {
          return true;
        } else {
          return false;
        }
      })
    });
    ```
  
    Updates to the the property of an attribute binding will result in automatic
    update of the  HTML attribute in the view's rendered HTML representation.
  
    `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html)
    documentation for more information about concatenated properties.
  
    ## Templates
  
    The HTML contents of a view's rendered representation are determined by its
    template. Templates can be any function that accepts an optional context
    parameter and returns a string of HTML that will be inserted within the
    view's tag. Most typically in Ember this function will be a compiled
    template.
  
    ```javascript
    AView = Ember.View.extend({
      template: Ember.HTMLBars.compile('I am the template')
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view">I am the template</div>
    ```
  
    Within an Ember application is more common to define a Handlebars templates as
    part of a page:
  
    ```html
    <script type='text/x-handlebars' data-template-name='some-template'>
      Hello
    </script>
    ```
  
    And associate it by name using a view's `templateName` property:
  
    ```javascript
    AView = Ember.View.extend({
      templateName: 'some-template'
    });
    ```
  
    If you have nested routes, your Handlebars template will look like this:
  
    ```html
    <script type='text/x-handlebars' data-template-name='posts/new'>
      <h1>New Post</h1>
    </script>
    ```
  
    And `templateName` property:
  
    ```javascript
    AView = Ember.View.extend({
      templateName: 'posts/new'
    });
    ```
  
    Using a value for `templateName` that does not have a template
    with a matching `data-template-name` attribute will throw an error.
  
    For views classes that may have a template later defined (e.g. as the block
    portion of a `{{view}}` helper call in another template or in
    a subclass), you can provide a `defaultTemplate` property set to compiled
    template function. If a template is not later provided for the view instance
    the `defaultTemplate` value will be used:
  
    ```javascript
    AView = Ember.View.extend({
      defaultTemplate: Ember.HTMLBars.compile('I was the default'),
      template: null,
      templateName: null
    });
    ```
  
    Will result in instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view">I was the default</div>
    ```
  
    If a `template` or `templateName` is provided it will take precedence over
    `defaultTemplate`:
  
    ```javascript
    AView = Ember.View.extend({
      defaultTemplate: Ember.HTMLBars.compile('I was the default')
    });
  
    aView = AView.create({
      template: Ember.HTMLBars.compile('I was the template, not default')
    });
    ```
  
    Will result in the following HTML representation when rendered:
  
    ```html
    <div id="ember1" class="ember-view">I was the template, not default</div>
    ```
  
    ## View Context
  
    The default context of the compiled template is the view's controller:
  
    ```javascript
    AView = Ember.View.extend({
      template: Ember.HTMLBars.compile('Hello {{excitedGreeting}}')
    });
  
    aController = Ember.Object.create({
      firstName: 'Barry',
      excitedGreeting: Ember.computed('content.firstName', function() {
        return this.get('content.firstName') + '!!!';
      })
    });
  
    aView = AView.create({
      controller: aController
    });
    ```
  
    Will result in an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view">Hello Barry!!!</div>
    ```
  
    A context can also be explicitly supplied through the view's `context`
    property. If the view has neither `context` nor `controller` properties, the
    `parentView`'s context will be used.
  
    ## Layouts
  
    Views can have a secondary template that wraps their main template. Like
    primary templates, layouts can be any function that  accepts an optional
    context parameter and returns a string of HTML that will be inserted inside
    view's tag. Views whose HTML element is self closing (e.g. `<input />`)
    cannot have a layout and this property will be ignored.
  
    Most typically in Ember a layout will be a compiled template.
  
    A view's layout can be set directly with the `layout` property or reference
    an existing template by name with the `layoutName` property.
  
    A template used as a layout must contain a single use of the
    `{{yield}}` helper. The HTML contents of a view's rendered `template` will be
    inserted at this location:
  
    ```javascript
    AViewWithLayout = Ember.View.extend({
      layout: Ember.HTMLBars.compile("<div class='my-decorative-class'>{{yield}}</div>"),
      template: Ember.HTMLBars.compile("I got wrapped")
    });
    ```
  
    Will result in view instances with an HTML representation of:
  
    ```html
    <div id="ember1" class="ember-view">
      <div class="my-decorative-class">
        I got wrapped
      </div>
    </div>
    ```
  
    See [Ember.Templates.helpers.yield](/api/classes/Ember.Templates.helpers.html#method_yield)
    for more information.
  
    ## Responding to Browser Events
  
    Views can respond to user-initiated events in one of three ways: method
    implementation, through an event manager, and through `{{action}}` helper use
    in their template or layout.
  
    ### Method Implementation
  
    Views can respond to user-initiated events by implementing a method that
    matches the event name. A `jQuery.Event` object will be passed as the
    argument to this method.
  
    ```javascript
    AView = Ember.View.extend({
      click: function(event) {
        // will be called when when an instance's
        // rendered element is clicked
      }
    });
    ```
  
    ### Event Managers
  
    Views can define an object as their `eventManager` property. This object can
    then implement methods that match the desired event names. Matching events
    that occur on the view's rendered HTML or the rendered HTML of any of its DOM
    descendants will trigger this method. A `jQuery.Event` object will be passed
    as the first argument to the method and an  `Ember.View` object as the
    second. The `Ember.View` will be the view whose rendered HTML was interacted
    with. This may be the view with the `eventManager` property or one of its
    descendant views.
  
    ```javascript
    AView = Ember.View.extend({
      eventManager: Ember.Object.create({
        doubleClick: function(event, view) {
          // will be called when when an instance's
          // rendered element or any rendering
          // of this view's descendant
          // elements is clicked
        }
      })
    });
    ```
  
    An event defined for an event manager takes precedence over events of the
    same name handled through methods on the view.
  
    ```javascript
    AView = Ember.View.extend({
      mouseEnter: function(event) {
        // will never trigger.
      },
      eventManager: Ember.Object.create({
        mouseEnter: function(event, view) {
          // takes precedence over AView#mouseEnter
        }
      })
    });
    ```
  
    Similarly a view's event manager will take precedence for events of any views
    rendered as a descendant. A method name that matches an event name will not
    be called if the view instance was rendered inside the HTML representation of
    a view that has an `eventManager` property defined that handles events of the
    name. Events not handled by the event manager will still trigger method calls
    on the descendant.
  
    ```javascript
    var App = Ember.Application.create();
    App.OuterView = Ember.View.extend({
      template: Ember.HTMLBars.compile("outer {{#view 'inner'}}inner{{/view}} outer"),
      eventManager: Ember.Object.create({
        mouseEnter: function(event, view) {
          // view might be instance of either
          // OuterView or InnerView depending on
          // where on the page the user interaction occurred
        }
      })
    });
  
    App.InnerView = Ember.View.extend({
      click: function(event) {
        // will be called if rendered inside
        // an OuterView because OuterView's
        // eventManager doesn't handle click events
      },
      mouseEnter: function(event) {
        // will never be called if rendered inside
        // an OuterView.
      }
    });
    ```
  
    ### `{{action}}` Helper
  
    See [Ember.Templates.helpers.action](/api/classes/Ember.Templates.helpers.html#method_action).
  
    ### Event Names
  
    All of the event handling approaches described above respond to the same set
    of events. The names of the built-in events are listed below. (The hash of
    built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
    can be registered by using `Ember.Application.customEvents`.
  
    Touch events:
  
    * `touchStart`
    * `touchMove`
    * `touchEnd`
    * `touchCancel`
  
    Keyboard events
  
    * `keyDown`
    * `keyUp`
    * `keyPress`
  
    Mouse events
  
    * `mouseDown`
    * `mouseUp`
    * `contextMenu`
    * `click`
    * `doubleClick`
    * `mouseMove`
    * `focusIn`
    * `focusOut`
    * `mouseEnter`
    * `mouseLeave`
  
    Form events:
  
    * `submit`
    * `change`
    * `focusIn`
    * `focusOut`
    * `input`
  
    HTML5 drag and drop events:
  
    * `dragStart`
    * `drag`
    * `dragEnter`
    * `dragLeave`
    * `dragOver`
    * `dragEnd`
    * `drop`
  
    ## `{{view}}` Helper
  
    Other `Ember.View` instances can be included as part of a view's template by
    using the `{{view}}` helper. See [Ember.Templates.helpers.view](/api/classes/Ember.Templates.helpers.html#method_view)
    for additional information.

    /**
      Normally, Ember's component model is "write-only". The component takes a
      bunch of attributes that it got passed in, and uses them to render its
      template.
       One nice thing about this model is that if you try to set a value to the
      same thing as last time, Ember (through HTMLBars) will avoid doing any
      work on the DOM.
       This is not just a performance optimization. If an attribute has not
      changed, it is important not to clobber the element's "hidden state".
      For example, if you set an input's `value` to the same value as before,
      it will clobber selection state and cursor position. In other words,
      setting an attribute is not **always** idempotent.
       This method provides a way to read an element's attribute and also
      update the last value Ember knows about at the same time. This makes
      setting an attribute idempotent.
       In particular, what this means is that if you get an `<input>` element's
      `value` attribute and then re-render the template with the same value,
      it will avoid clobbering the cursor and selection position.
       Since most attribute sets are idempotent in the browser, you typically
      can get away with reading attributes using jQuery, but the most reliable
      way to do so is through this method.

  /**
    HTMLBars delegates the runtime behavior of a template to
    hooks provided by the host environment. These hooks explain
    the lexical environment of a Handlebars template, the internal
    representation of references, and the interaction between an
    HTMLBars template and the DOM it is managing.
  
    While HTMLBars host hooks have access to all of this internal
    machinery, templates and helpers have access to the abstraction
    provided by the host hooks.
  
    ## The Lexical Environment
  
    The default lexical environment of an HTMLBars template includes:
  
    * Any local variables, provided by *block arguments*
    * The current value of `self`
  
    ## Simple Nesting
  
    Let's look at a simple template with a nested block:
  
    ```hbs
    <h1>{{title}}</h1>
  
    {{#if author}}
      <p class="byline">{{author}}</p>
    {{/if}}
    ```
  
    In this case, the lexical environment at the top-level of the
    template does not change inside of the `if` block. This is
    achieved via an implementation of `if` that looks like this:
  
    ```js
    registerHelper('if', function(params) {
      if (!!params[0]) {
        return this.yield();
      }
    });
    ```
  
    A call to `this.yield` invokes the child template using the
    current lexical environment.
  
    ## Block Arguments
  
    It is possible for nested blocks to introduce new local
    variables:
  
    ```hbs
    {{#count-calls as |i|}}
    <h1>{{title}}</h1>
    <p>Called {{i}} times</p>
    {{/count}}
    ```
  
    In this example, the child block inherits its surrounding
    lexical environment, but augments it with a single new
    variable binding.
  
    The implementation of `count-calls` supplies the value of
    `i`, but does not otherwise alter the environment:
  
    ```js
    var count = 0;
    registerHelper('count-calls', function() {
      return this.yield([ ++count ]);
    });
    ```

    This host hook is a workhorse of the system. It is invoked
    whenever a block is encountered, and is responsible for

    The helper should be invoked with:
  
    - `{Array} params`: the parameters passed to the helper
      in the template.
    - `{Object} hash`: an object containing the keys and values passed
      in the hash position in the template.
  
    The values in `params` and `hash` will already be resolved
    through a previous call to the `get` host hook.
  
    The helper should be invoked with a `this` value that is
    an object with one field:
  
    `{Function} yield`: when invoked, this function executes the
    block with the current scope. It takes an optional array of
    block parameters. If block parameters are supplied, HTMLBars
    will invoke the `bindLocal` host hook to bind the supplied
    values to the block arguments provided by the template.
  
    In general, the default implementation of `block` should work
    for most host environments. It delegates to other host hooks
    where appropriate, and properly invokes the helper with the
    appropriate arguments.

    This host hook is similar to the `block` host hook, but it
    invokes helpers that do not supply an attached block.
  
    Like the `block` hook, the helper should be invoked with:
  
    - `{Array} params`: the parameters passed to the helper
      in the template.
    - `{Object} hash`: an object containing the keys and values passed
      in the hash position in the template.
  
    The values in `params` and `hash` will already be resolved
    through a previous call to the `get` host hook.
  
    In general, the default implementation of `inline` should work
    for most host environments. It delegates to other host hooks
    where appropriate, and properly invokes the helper with the
    appropriate arguments.
  
    The default implementation of `inline` also makes `partial`
    a keyword. Instead of invoking a helper named `partial`,
    it invokes the `partial` host hook.

    active but have their context changed.
  
    Take a list of old handlers and new handlers and partition

    * unchanged: the handler was active in both the old and
      new URL, and its context remains the same
    * updated context: the handler was active in both the
      old and new URL, but its context changed. The handler's
      `setup` method, if any, will be called with the new
      context.
    * exited: the handler was active in the old URL, but is
      no longer active.
    * entered: the handler was not active in the old URL, but
      is now active.

      context
    * `entered`: a list of `HandlerInfo` objects that represent
      handlers that are newly active
    * `exited`: a list of `HandlerInfo` objects that are no
      longer active.
    * `unchanged`: a list of `HanderInfo` objects that remain active.

    `RSVP.allSettled` is similar to `RSVP.all`, but instead of implementing
    a fail-fast method, it waits until all the promises have returned and
    shows you all the results. This is useful if you want to handle multiple
    promises' failure states together as a set.
  
    Returns a promise that is fulfilled when all the given promises have been
    settled. The return promise is fulfilled with an array of the states of
    the promises passed into the `promises` array argument.
  
    Each state object will either indicate fulfillment or rejection, and
    provide the corresponding value or reason. The states will take one of
    the following formats:
  
    ```javascript
    { state: 'fulfilled', value: value }
      or
    { state: 'rejected', reason: reason }
    ```
  
    Example:
  
    ```javascript
    var promise1 = RSVP.Promise.resolve(1);
    var promise2 = RSVP.Promise.reject(new Error('2'));
    var promise3 = RSVP.Promise.reject(new Error('3'));
    var promises = [ promise1, promise2, promise3 ];
  
    RSVP.allSettled(promises).then(function(array){
      // array == [
      //   { state: 'fulfilled', value: 1 },
      //   { state: 'rejected', reason: Error },
      //   { state: 'rejected', reason: Error }
      // ]
      // Note that for the second item, reason.message will be '2', and for the
      // third item, reason.message will be '3'.
    }, function(error) {
      // Not run. (This block would only be called if allSettled had failed,
      // for instance if passed an incorrect argument type.)

   `RSVP.filter` is similar to JavaScript's native `filter` method, except that it

    each item in given to `promises`. `RSVP.filter` returns a promise that will
    become fulfilled with the result of running `filterFn` on the values the
    promises become fulfilled with.
  
    For example:
  
    ```javascript
  
    var promise1 = RSVP.resolve(1);
    var promise2 = RSVP.resolve(2);
    var promise3 = RSVP.resolve(3);

    ```
  
    If any of the `promises` given to `RSVP.filter` are rejected, the first promise
    that is rejected will be given as an argument to the returned promise's
    rejection handler. For example:
  
    ```javascript
    var promise1 = RSVP.resolve(1);
    var promise2 = RSVP.reject(new Error('2'));
    var promise3 = RSVP.reject(new Error('3'));

    }, function(reason) {
      // reason.message === '2'
    });

    `RSVP.filter` will also wait for any promises returned from `filterFn`.

  /**
    `RSVP.hashSettled` is similar to `RSVP.allSettled`, but takes an object
    instead of an array for its `promises` argument.
  
    Unlike `RSVP.all` or `RSVP.hash`, which implement a fail-fast method,
    but like `RSVP.allSettled`, `hashSettled` waits until all the
    constituent promises have returned and then shows you all the results
    with their states and values/reasons. This is useful if you want to
    handle multiple promises' failure states together as a set.
  
    Returns a promise that is fulfilled when all the given promises have been
    settled, or rejected if the passed parameters are invalid.
  
    The returned promise is fulfilled with a hash that has the same key names as
    the `promises` object argument. If any of the values in the object are not
    promises, they will be copied over to the fulfilled object and marked with state
    'fulfilled'.
  
    Example:
  
    ```javascript
    var promises = {
      myPromise: RSVP.Promise.resolve(1),
      yourPromise: RSVP.Promise.resolve(2),
      theirPromise: RSVP.Promise.resolve(3),
      notAPromise: 4
    };
  
    RSVP.hashSettled(promises).then(function(hash){
      // hash here is an object that looks like:
      // {
      //   myPromise: { state: 'fulfilled', value: 1 },
      //   yourPromise: { state: 'fulfilled', value: 2 },
      //   theirPromise: { state: 'fulfilled', value: 3 },
      //   notAPromise: { state: 'fulfilled', value: 4 }
      // }
    });
    ```
  
    If any of the `promises` given to `RSVP.hash` are rejected, the state will
    be set to 'rejected' and the reason for rejection provided.
  
    Example:
  
    ```javascript
    var promises = {
      myPromise: RSVP.Promise.resolve(1),
      rejectedPromise: RSVP.Promise.reject(new Error('rejection')),
      anotherRejectedPromise: RSVP.Promise.reject(new Error('more rejection')),
    };
  
    RSVP.hashSettled(promises).then(function(hash){
      // hash here is an object that looks like:
      // {
      //   myPromise:              { state: 'fulfilled', value: 1 },
      //   rejectedPromise:        { state: 'rejected', reason: Error },
      //   anotherRejectedPromise: { state: 'rejected', reason: Error },
      // }
      // Note that for rejectedPromise, reason.message == 'rejection',
      // and for anotherRejectedPromise, reason.message == 'more rejection'.
    });
    ```
  
    An important note: `RSVP.hashSettled` is intended for plain JavaScript objects that
    are just a set of keys and values. `RSVP.hashSettled` will NOT preserve prototype
    chains.
  
    Example:
  
    ```javascript
    function MyConstructor(){
      this.example = RSVP.Promise.resolve('Example');
    }
  
    MyConstructor.prototype = {
      protoProperty: RSVP.Promise.resolve('Proto Property')
    };
  
    var myObject = new MyConstructor();
  
    RSVP.hashSettled(myObject).then(function(hash){
      // protoProperty will not be present, instead you will just have an
      // object that looks like:
      // {
      //   example: { state: 'fulfilled', value: 'Example' }
      // }
      //
      // hash.hasOwnProperty('protoProperty'); // false

    browser when you'd prefer to use promises over using callbacks. For example,
    `denodeify` transforms the following:
  
    ```javascript
    var fs = require('fs');
  
    fs.readFile('myfile.txt', function(err, data){
      if (err) return handleError(err);
      handleData(data);

    ```javascript
    var fs = require('fs');
    var readFile = RSVP.denodeify(fs.readFile);
  
    readFile('myfile.txt').then(handleData, handleError);
    ```
  
    If the node function has multiple success parameters, then `denodeify`
    just returns the first one:
  
    ```javascript
    var request = RSVP.denodeify(require('request'));
  
    request('http://example.com').then(function(res) {
      // ...
    });
    ```
  
    However, if you need all success parameters, setting `denodeify`'s
    second parameter to `true` causes it to return all success parameters
    as an array:
  
    ```javascript
    var request = RSVP.denodeify(require('request'), true);
  
    request('http://example.com').then(function(result) {
      // result[0] -> res
      // result[1] -> body
    });
    ```
  
    Or if you pass it an array with names it returns the parameters as a hash:
  
    ```javascript
    var request = RSVP.denodeify(require('request'), ['res', 'body']);
  
    request('http://example.com').then(function(result) {
      // result.res
      // result.body
    });
    ```
  
    Sometimes you need to retain the `this`:
  
    ```javascript
    var app = require('express')();
    var render = RSVP.denodeify(app.render.bind(app));
    ```
  
    The denodified function inherits from the original function. It works in all
    environments, except IE 10 and below. Consequently all properties of the original
    function are available to you. However, any properties you change on the
    denodeified function won't be changed on the original function. Example:
  
    ```javascript
    var request = RSVP.denodeify(require('request')),
        cookieJar = request.jar(); // <- Inheritance is used here
  
    request('http://example.com', {jar: cookieJar}).then(function(res) {
      // cookieJar.cookies holds now the cookies returned by example.com
    });
    ```
  
    Using `denodeify` makes it easier to compose asynchronous operations instead
    of using callbacks. For example, instead of:
  
    ```javascript
    var fs = require('fs');
  
    fs.readFile('myfile.txt', function(err, data){
      if (err) { ... } // Handle error
      fs.writeFile('myfile2.txt', data, function(err){
        if (err) { ... } // Handle error
        console.log('done')
      });
    });
    ```
  
    you can chain the operations together using `then` from the returned promise:
  
    ```javascript
    var fs = require('fs');
    var readFile = RSVP.denodeify(fs.readFile);
    var writeFile = RSVP.denodeify(fs.writeFile);
  
    readFile('myfile.txt').then(function(data){
      return writeFile('myfile2.txt', data);
    }).then(function(){
      console.log('done')
    }).catch(function(error){
      // Handle error
    });
    ```
  
    @method denodeify
    @static
    @for RSVP
    @param {Function} nodeFunc a 'node-style' function that takes a callback as
    its last argument. The callback expects an error to be passed as its first
    argument (if an error occurred, otherwise null), and the value from the
    operation as its second argument ('function(err, value){ }').
    @param {Boolean|Array} argumentNames An optional paramter that if set
    to `true` causes the promise to fulfill with the callback's success arguments
    as an array. This is useful if the node function has multiple success
    paramters. If you set this paramter to an array with names, the promise will
    fulfill with a hash with these names as keys and the success parameters as
    values.

  /**
    Promise objects represent the eventual result of an asynchronous operation. The
    primary way of interacting with a promise is through its `then` method, which
    registers callbacks to receive either a promise’s eventual value or the reason
    why the promise cannot be fulfilled.
  
    Terminology
    -----------
  
    - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
    - `thenable` is an object or function that defines a `then` method.
    - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
    - `exception` is a value that is thrown using the throw statement.
    - `reason` is a value that indicates why a promise was rejected.
    - `settled` the final resting state of a promise, fulfilled or rejected.
  
    A promise can be in one of three states: pending, fulfilled, or rejected.
  
    Promises that are fulfilled have a fulfillment value and are in the fulfilled
    state.  Promises that are rejected have a rejection reason and are in the
    rejected state.  A fulfillment value is never a thenable.
  
    Promises can also be said to *resolve* a value.  If this value is also a
    promise, then the original promise's settled state will match the value's
    settled state.  So a promise that *resolves* a promise that rejects will
    itself reject, and a promise that *resolves* a promise that fulfills will
    itself fulfill.
  
  
    Basic Usage:
    ------------
  
    ```js
    var promise = new Promise(function(resolve, reject) {
      // on success
      resolve(value);
  
      // on failure
      reject(reason);
    });
  
    promise.then(function(value) {
      // on fulfillment
    }, function(reason) {
      // on rejection
    });
    ```
  
    Advanced Usage:
    ---------------
  
    Promises shine when abstracting away asynchronous interactions such as
    `XMLHttpRequest`s.
  
    ```js
    function getJSON(url) {
      return new Promise(function(resolve, reject){
        var xhr = new XMLHttpRequest();
  
        xhr.open('GET', url);
        xhr.onreadystatechange = handler;
        xhr.responseType = 'json';
        xhr.setRequestHeader('Accept', 'application/json');
        xhr.send();
  
        function handler() {
          if (this.readyState === this.DONE) {
            if (this.status === 200) {
              resolve(this.response);
            } else {
              reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
            }
          }
        };
      });
    }
  
    getJSON('/posts.json').then(function(json) {
      // on fulfillment
    }, function(reason) {
      // on rejection
    });
    ```
  
    Unlike callbacks, promises are great composable primitives.
  
    ```js
    Promise.all([
      getJSON('/posts'),
      getJSON('/comments')
    ]).then(function(values){
      values[0] // => postsJSON
      values[1] // => commentsJSON
  
      return values;
    });
    ```

    @param {function} resolver
    @param {String} label optional string for labeling the promise.

  function Promise(resolver, label) {
    this._id = counter++;
    this._label = label;
    this._state = undefined;
    this._result = undefined;
    this._subscribers = [];

    if (_config.config.instrument) {
      _instrument.default('created', this);
    }

    if (_internal.noop !== resolver) {
      if (!_utils.isFunction(resolver)) {
        needsResolver();
      }

      if (!(this instanceof Promise)) {

  Promise.all = _promiseAll.default;
  Promise.race = _promiseRace.default;
  Promise.resolve = _promiseResolve.default;
  Promise.reject = _promiseReject.default;

  Promise.prototype = {
    constructor: Promise,

    _guidKey: guidKey,

    _onerror: function (reason) {
      _config.config.trigger('error', reason);
    },

    /**
      The primary way of interacting with a promise is through its `then` method,
      which registers callbacks to receive either a promise's eventual value or the
      reason why the promise cannot be fulfilled.
    
      ```js
      findUser().then(function(user){
        // user is available
      }, function(reason){
        // user is unavailable, and you are given the reason why
      });
      ```
    
      Chaining
      --------
    
      The return value of `then` is itself a promise.  This second, 'downstream'
      promise is resolved with the return value of the first promise's fulfillment
      or rejection handler, or rejected if the handler throws an exception.
    
      ```js
      findUser().then(function (user) {
        return user.name;
      }, function (reason) {
        return 'default name';
      }).then(function (userName) {
        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
        // will be `'default name'`
      });
    
      findUser().then(function (user) {
        throw new Error('Found user, but still unhappy');
      }, function (reason) {
        throw new Error('`findUser` rejected and we're unhappy');
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
        // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
      });
      ```
      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
    
      ```js
      findUser().then(function (user) {
        throw new PedagogicalException('Upstream error');
      }).then(function (value) {
        // never reached
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // The `PedgagocialException` is propagated all the way down to here
      });
      ```
    
      Assimilation
      ------------
    
      Sometimes the value you want to propagate to a downstream promise can only be
      retrieved asynchronously. This can be achieved by returning a promise in the
      fulfillment or rejection handler. The downstream promise will then be pending
      until the returned promise is settled. This is called *assimilation*.
    
      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // The user's comments are now available
      });
      ```
    
      If the assimliated promise rejects, then the downstream promise will also reject.
    
      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // If `findCommentsByAuthor` fulfills, we'll have the value here
      }, function (reason) {
        // If `findCommentsByAuthor` rejects, we'll have the reason here
      });
      ```
    
      Simple Example

      Synchronous Example
    
      ```javascript
      var result;
    
      try {

    ```javascript
    var promise1 = RSVP.resolve(1);
    var promise2 = RSVP.resolve(2);
    var promise3 = RSVP.resolve(3);
    var promises = [ promise1, promise2, promise3 ];
  
    RSVP.Promise.all(promises).then(function(array){
      // The array here would be [ 1, 2, 3 ];
    });
    ```
  
    If any of the `promises` given to `RSVP.all` are rejected, the first promise
    that is rejected will be given as an argument to the returned promises's
    rejection handler. For example:
  
    Example:
  
    ```javascript
    var promise1 = RSVP.resolve(1);
    var promise2 = RSVP.reject(new Error("2"));
    var promise3 = RSVP.reject(new Error("3"));
    var promises = [ promise1, promise2, promise3 ];
  
    RSVP.Promise.all(promises).then(function(array){
      // Code here never runs because there are rejected promises!
    }, function(error) {
      // error.message === "2"
    });
    ```
  
    @method all
    @static
    @param {Array} entries array of promises
    @param {String} label optional string for labeling the promise.
    Useful for tooling.
    @return {Promise} promise that is fulfilled when all `promises` have been
    fulfilled, or rejected if any of them become rejected.

  /**
    `RSVP.Promise.race` returns a new promise which is settled in the same way as the
    first passed promise to settle.
  
    Example:
  
    ```javascript
    var promise1 = new RSVP.Promise(function(resolve, reject){
      setTimeout(function(){
        resolve('promise 1');
      }, 200);
    });
  
    var promise2 = new RSVP.Promise(function(resolve, reject){
      setTimeout(function(){
        resolve('promise 2');
      }, 100);
    });
  
    RSVP.Promise.race([promise1, promise2]).then(function(result){
      // result === 'promise 2' because it was resolved before promise1
      // was resolved.
    });
    ```
  
    `RSVP.Promise.race` is deterministic in that only the state of the first
    settled promise matters. For example, even if other promises given to the
    `promises` array argument are resolved, but the first settled promise has
    become rejected before the other promises became fulfilled, the returned
    promise will become rejected:
  
    ```javascript
    var promise1 = new RSVP.Promise(function(resolve, reject){
      setTimeout(function(){
        resolve('promise 1');
      }, 200);
    });
  
    var promise2 = new RSVP.Promise(function(resolve, reject){
      setTimeout(function(){
        reject(new Error('promise 2'));
      }, 100);
    });
  
    RSVP.Promise.race([promise1, promise2]).then(function(result){
      // Code here never runs
    }, function(reason){
      // reason.message === 'promise 2' because promise 2 became rejected before
      // promise 1 became fulfilled
    });
    ```
  
    An example real-world use case is implementing timeouts:
  
    ```javascript
    RSVP.Promise.race([ajax('foo.json'), timeout(5000)])
    ```
  
    @method race
    @static
    @param {Array} promises array of promises to observe
    @param {String} label optional string for describing the promise returned.
    Useful for tooling.
    @return {Promise} a promise which settles in the same way as the first passed
    promise to settle.

    `RSVP.rethrow` will rethrow an error on the next turn of the JavaScript event
    loop in order to aid debugging.
  
    Promises A+ specifies that any exceptions that occur with a promise must be
    caught by the promises implementation and bubbled to the last handler. For
    this reason, it is recommended that you always specify a second rejection
    handler function to `then`. However, `RSVP.rethrow` will throw the exception
    outside of the promise, so it bubbles up to your console if in the browser,
    or domain/cause uncaught exception in Node. `rethrow` will also throw the
    error again so the error can be handled by the promise per the spec.
  
    ```javascript
    function throws(){
      throw new Error('Whoops!');
    }
  
    var promise = new RSVP.Promise(function(resolve, reject){
      throws();
    });

      // Code here doesn't run because the promise became rejected due to an
      // error!
    }, function (err){
      // handle the error here
    });
    ```
  
    The 'Whoops' error will be thrown on the next turn of the event loop
    and you can watch for it in your console. You can also handle it using a
    rejection handler given to `.then` or `.catch` on the returned promise.
