is completely\n    isolated. Properties accessed in its templates go\n    to the view object and actions are targeted at\n    the view object. There is no access to the\n    surrounding context or outer controller; all\n    contextual information must be passed in.\n  \n    The easiest way to create a `Component` is via\n    a template. If you name a template\n    `app/templates/components/my-foo.hbs`, you will be able to use\n    `{{my-foo}}` in other templates, which will make\n    an instance of the isolated component.\n  \n    ```app/templates/components/my-foo.hbs\n    {{person-profile person=currentUser}}\n    ```\n  \n    ```app/templates/components/person-profile.hbs\n    <h1>{{person.title}}</h1>\n    <img src={{person.avatar}}>\n    <p class='signature'>{{person.signature}}</p>\n    ```\n  \n    You can use `yield` inside a template to\n    include the **contents** of any block attached to\n    the component. The block will be executed in the\n    context of the surrounding context or outer controller:\n  \n    ```handlebars\n    {{#person-profile person=currentUser}}\n      <p>Admin mode</p>\n      {{! Executed in the controller's context. }}\n    {{/person-profile}}\n    ```\n  \n    ```app/templates/components/person-profile.hbs\n    <h1>{{person.title}}</h1>\n    {{! Executed in the component's context. }}\n    {{yield}} {{! block contents }}\n    ```\n  \n    If you want to customize the component, in order to\n    handle events or actions, you implement a subclass\n    of `Component` named after the name of the\n    component.\n  \n    For example, you could implement the action\n    `hello` for the `person-profile` component:\n  \n    ```app/components/person-profile.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      actions: {\n        hello(name) {\n          console.log(\"Hello\", name);\n        }\n      }\n    });\n    ```\n  \n    And then use it in the component's template:\n  \n    ```app/templates/components/person-profile.hbs\n    <h1>{{person.title}}</h1>\n    {{yield}} <!-- block contents -->\n    <button {{action 'hello' person.name}}>\n      Say Hello to {{person.name}}\n    </button>\n    ```\n  \n    Components must have a `-` in their name to avoid\n    conflicts with built-in controls that wrap HTML\n    elements. This is consistent with the same\n    requirement in web components.\n  \n    ## HTML Tag\n  \n    The default HTML tag name used for a component's DOM representation is `div`.\n    This can be customized by setting the `tagName` property.\n    The following component class:\n  \n    ```app/components/emphasized-paragraph.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      tagName: 'em'\n    });\n    ```\n  \n    Would result in instances with the following HTML:\n  \n    ```html\n    <em id=\"ember1\" class=\"ember-view\"></em>\n    ```\n  \n    ## HTML `class` Attribute\n  \n    The HTML `class` attribute of a component's tag can be set by providing a\n    `classNames` property that is set to an array of strings:\n  \n    ```app/components/my-widget.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      classNames: ['my-class', 'my-other-class']\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view my-class my-other-class\"></div>\n    ```\n  \n    `class` attribute values can also be set by providing a `classNameBindings`\n    property set to an array of properties names for the component. The return value\n    of these properties will be added as part of the value for the components's `class`\n    attribute. These properties can be computed properties:\n  \n    ```app/components/my-widget.js\n    import Component from '@ember/component';\n    import { computed } from '@ember/object';\n  \n    export default Component.extend({\n      classNameBindings: ['propertyA', 'propertyB'],\n  \n      propertyA: 'from-a',\n      propertyB: computed(function() {\n        if (someLogic) { return 'from-b'; }\n      })\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view from-a from-b\"></div>\n    ```\n  \n    If the value of a class name binding returns a boolean the property name\n    itself will be used as the class name if the property is true.\n    The class name will not be added if the value is `false` or `undefined`.\n  \n    ```app/components/my-widget.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      classNameBindings: ['hovered'],\n  \n      hovered: true\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view hovered\"></div>\n    ```\n  \n    When using boolean class name bindings you can supply a string value other\n    than the property name for use as the `class` HTML attribute by appending the\n    preferred value after a \":\" character when defining the binding:\n  \n    ```app/components/my-widget.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      classNameBindings: ['awesome:so-very-cool'],\n  \n      awesome: true\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view so-very-cool\"></div>\n    ```\n  \n    Boolean value class name bindings whose property names are in a\n    camelCase-style format will be converted to a dasherized format:\n  \n    ```app/components/my-widget.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      classNameBindings: ['isUrgent'],\n  \n      isUrgent: true\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view is-urgent\"></div>\n    ```\n  \n    Class name bindings can also refer to object values that are found by\n    traversing a path relative to the component itself:\n  \n    ```app/components/my-widget.js\n    import Component from '@ember/component';\n    import EmberObject from '@ember/object';\n  \n    export default Component.extend({\n      classNameBindings: ['messages.empty'],\n  \n      messages: EmberObject.create({\n        empty: true\n      })\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view empty\"></div>\n    ```\n  \n    If you want to add a class name for a property which evaluates to true and\n    and a different class name if it evaluates to false, you can pass a binding\n    like this:\n  \n    ```app/components/my-widget.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      classNameBindings: ['isEnabled:enabled:disabled'],\n      isEnabled: true\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view enabled\"></div>\n    ```\n  \n    When isEnabled is `false`, the resulting HTML representation looks like\n    this:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view disabled\"></div>\n    ```\n  \n    This syntax offers the convenience to add a class if a property is `false`:\n  \n    ```app/components/my-widget.js\n    import Component from '@ember/component';\n  \n    // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false\n    export default Component.extend({\n      classNameBindings: ['isEnabled::disabled'],\n      isEnabled: true\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view\"></div>\n    ```\n  \n    When the `isEnabled` property on the component is set to `false`, it will result\n    in component instances with an HTML representation of:\n  \n    ```html\n    <div id=\"ember1\" class=\"ember-view disabled\"></div>\n    ```\n  \n    Updates to the value of a class name binding will result in automatic\n    update of the  HTML `class` attribute in the component's rendered HTML\n    representation. If the value becomes `false` or `undefined` the class name\n    will be removed.\n    Both `classNames` and `classNameBindings` are concatenated properties. See\n    [EmberObject](/api/ember/release/classes/EmberObject) documentation for more\n    information about concatenated properties.\n  \n    ## HTML Attributes\n  \n    The HTML attribute section of a component's tag can be set by providing an\n    `attributeBindings` property set to an array of property names on the component.\n    The return value of these properties will be used as the value of the component's\n    HTML associated attribute:\n  \n    ```app/components/my-anchor.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      tagName: 'a',\n      attributeBindings: ['href'],\n  \n      href: 'http://google.com'\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <a id=\"ember1\" class=\"ember-view\" href=\"http://google.com\"></a>\n    ```\n  \n    One property can be mapped on to another by placing a \":\" between\n    the source property and the destination property:\n  \n    ```app/components/my-anchor.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      tagName: 'a',\n      attributeBindings: ['url:href'],\n  \n      url: 'http://google.com'\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <a id=\"ember1\" class=\"ember-view\" href=\"http://google.com\"></a>\n    ```\n  \n    Namespaced attributes (e.g. `xlink:href`) are supported, but have to be\n    mapped, since `:` is not a valid character for properties in Javascript:\n  \n    ```app/components/my-use.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      tagName: 'use',\n      attributeBindings: ['xlinkHref:xlink:href'],\n  \n      xlinkHref: '#triangle'\n    });\n    ```\n  \n    Will result in component instances with an HTML representation of:\n  \n    ```html\n    <use xlink:href=\"#triangle\"></use>\n    ```\n  \n    If the return value of an `attributeBindings` monitored property is a boolean\n    the attribute will be present or absent depending on the value:\n  \n    ```app/components/my-text-input.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      tagName: 'input',\n      attributeBindings: ['disabled'],\n  \n      disabled: false\n    });\n    ```\n  \n    Will result in a component instance with an HTML representation of:\n  \n    ```html\n    <input id=\"ember1\" class=\"ember-view\" />\n    ```\n  \n    `attributeBindings` can refer to computed properties:\n  \n    ```app/components/my-text-input.js\n    import Component from '@ember/component';\n    import { computed } from '@ember/object';\n  \n    export default Component.extend({\n      tagName: 'input',\n      attributeBindings: ['disabled'],\n  \n      disabled: computed(function() {\n        if (someLogic) {\n          return true;\n        } else {\n          return false;\n        }\n      })\n    });\n    ```\n  \n    To prevent setting an attribute altogether, use `null` or `undefined` as the\n    return value of the `attributeBindings` monitored property:\n  \n    ```app/components/my-text-input.js\n    import Component from '@ember/component';\n  \n    export default Component.extend({\n      tagName: 'form',\n      attributeBindings: ['novalidate'],\n      novalidate: null\n    });\n    ```\n  \n    Updates to the property of an attribute binding will result in automatic\n    update of the  HTML attribute in the component's rendered HTML representation.\n    `attributeBindings` is a concatenated property. See [EmberObject](/api/ember/release/classes/EmberObject)\n    documentation for more information about concatenated properties.\n  \n    ## Layouts\n  \n    See [Ember.Templates.helpers.yield](/api/ember/release/classes/Ember.Templates.helpers/methods/yield?anchor=yield)\n    for more information.\n  \n    Layout can be used to wrap content in a component. In addition\n    to wrapping content in a Component's template, you can also use\n    the public layout API in your Component JavaScript.\n  \n    ```app/templates/components/person-profile.hbs\n      <h1>Person's Title</h1>\n      <div class='details'>{{yield}}</div>\n    ```\n  \n    ```app/components/person-profile.js\n      import Component from '@ember/component';\n      import layout from '../templates/components/person-profile';\n  \n      export default Component.extend({\n        layout\n      });\n    ```\n  \n    If you call the `person-profile` component like so:\n  \n    ```\n    {{#person-profile}}\n      <h2>Chief Basket Weaver</h2>\n      <h3>Fisherman Industries</h3>\n    {{/person-profile}}\n  \n    It will result in the following HTML output:\n  \n    ```html\n      <h1>Person's Title</h1>\n      <div class=\"details\">\n        <h2>Chief Basket Weaver</h2>\n        <h3>Fisherman Industries</h3>\n      </div>\n    ```\n  \n    ## Responding to Browser Events\n  \n    Components can respond to user-initiated events in one of three ways: method\n    implementation, through an event manager, and through `{{action}}` helper use\n    in their template or layout.\n  \n    ### Method Implementation\n  \n    Components can respond to user-initiated events by implementing a method that\n    matches the event name.

The component takes a\n      bunch of attributes that it got passed in, and uses them to render its\n      template.\n       One nice thing about this model is that if you try to set a value to the\n      same thing as last time, Ember (through HTMLBars) will avoid doing any\n      work on the DOM.\n       This is not just a performance optimization. If an attribute has not\n      changed, it is important not to clobber the element's \"hidden state\".\n      For example, if you set an input's `value` to the same value as before,\n      it will clobber selection state and cursor position. In other words,\n      setting an attribute is not **always** idempotent.\n       This method provides a way to read an element's attribute and also\n      update the last value Ember knows about at the same time. This makes\n      setting an attribute idempotent.\n       In particular, what this means is that if you get an `<input>` element's\n      `value` attribute and then re-render the template with the same value,\n      it will avoid clobbering the cursor and selection position.\n      Since most attribute sets are idempotent in the browser, you typically\n      can get away with reading attributes using jQuery, but the most reliable\n      way to do so is through this method.\n      @method readDOMAttr\n       @param {String} name the name of the attribute\n      @return String\n      @public\n     */\n    readDOMAttr(name) {\n      // TODO revisit this\n      let element = (0, _views.getViewElement)(this);\n      let isSVG = element.namespaceURI === _runtime2.SVG_NAMESPACE;\n      let { type, normalized } = (0, _runtime2.normalizeProperty)(element, name);\n      if (isSVG || type === 'attr') {\n        return element.getAttribute(normalized);\n      }\n      return element[normalized];\n    },\n    /**\n     The WAI-ARIA role of the control represented by this view.

This can\n      be overridden for a single use of `{{link-to}}` by supplying\n      a `tagName` option:\n    \n      ```handlebars\n      {{#link-to 'photoGallery' tagName=\"li\"}}\n        Great Hamster Photos\n      {{/link-to}}\n      ```\n    \n      ```html\n      <li>\n        Great Hamster Photos\n      </li>\n      ```\n    \n      To override this option for your entire application, see\n      \"Overriding Application-wide Defaults\".\n    \n      ### Disabling the `link-to` component\n      By default `{{link-to}}` is enabled.\n      any passed value to the `disabled` component property will disable\n      the `link-to` component.\n    \n      static use: the `disabled` option:\n    \n      ```handlebars\n      {{#link-to 'photoGallery' disabled=true}}\n        Great Hamster Photos\n      {{/link-to}}\n      ```\n    \n      dynamic use: the `disabledWhen` option:\n    \n      ```handlebars\n      {{#link-to 'photoGallery' disabledWhen=controller.someProperty}}\n        Great Hamster Photos\n      {{/link-to}}\n      ```\n    \n      any truthy value passed to `disabled` will disable it except `undefined`.\n    \n      See \"Overriding Application-wide Defaults\" for more.\n    \n      ### Handling `href`\n      `{{link-to}}` will use your application's Router to\n      fill the element's `href` property with a url that\n      matches the path to the supplied `routeName` for your\n      router's configured `Location` scheme, which defaults\n      to HashLocation.\n    \n      ### Handling current route\n      `{{link-to}}` will apply a CSS class name of 'active'\n      when the application's current route matches\n      the supplied routeName. For example, if the application's\n      current route is 'photoGallery.recent' the following\n      use of `{{link-to}}`:\n    \n      ```handlebars\n      {{#link-to 'photoGallery.recent'}}\n        Great Hamster Photos\n      {{/link-to}}\n      ```\n    \n      will result in\n    \n      ```html\n      <a href=\"/hamster-photos/this-week\" class=\"active\">\n        Great Hamster Photos\n      </a>\n      ```\n    \n      The CSS class name used for active classes can be customized\n      for a single use of `{{link-to}}` by passing an `activeClass`\n      option:\n    \n      ```handlebars\n      {{#link-to 'photoGallery.recent' activeClass=\"current-url\"}}\n        Great Hamster Photos\n      {{/link-to}}\n      ```\n    \n      ```html\n      <a href=\"/hamster-photos/this-week\" class=\"current-url\">\n        Great Hamster Photos\n      </a>\n      ```\n    \n      To override this option for your entire application, see\n      \"Overriding Application-wide Defaults\".\n    \n      ### Keeping a link active for other routes\n    \n      If you need a link to be 'active' even when it doesn't match\n      the current route, you can use the `current-when` argument.\n    \n      ```handlebars\n      {{#link-to 'photoGallery' current-when='photos'}}\n        Photo Gallery\n      {{/link-to}}\n      ```\n    \n      This may be helpful for keeping links active for:\n    \n      * non-nested routes that are logically related\n      * some secondary menu approaches\n      * 'top navigation' with 'sub navigation' scenarios\n    \n      A link will be active if `current-when` is `true` or the current\n      route is the route this link would transition to.\n    \n      To match multiple routes 'space-separate' the routes:\n    \n      ```handlebars\n      {{#link-to 'gallery' current-when='photos drawings paintings'}}\n        Art Gallery\n      {{/link-to}}\n      ```\n    \n      ### Supplying a model\n      An optional model argument can be used for routes whose\n      paths contain dynamic segments. This argument will become\n      the model context of the linked route:\n    \n      ```javascript\n      Router.map(function() {\n        this.route(\"photoGallery\", {path: \"hamster-photos/:photo_id\"});\n      });\n      ```\n    \n      ```handlebars\n      {{#link-to 'photoGallery' aPhoto}}\n        {{aPhoto.title}}\n      {{/link-to}}\n      ```\n    \n      ```html\n      <a href=\"/hamster-photos/42\">\n        Tomster\n      </a>\n      ```\n    \n      ### Supplying multiple models\n      For deep-linking to route paths that contain multiple\n      dynamic segments, multiple model arguments can be used.\n      As the router transitions through the route path, each\n      supplied model argument will become the context for the\n      route with the dynamic segments:\n    \n      ```javascript\n      Router.map(function() {\n        this.route(\"photoGallery\", { path: \"hamster-photos/:photo_id\" }, function() {\n          this.route(\"comment\", {path: \"comments/:comment_id\"});\n        });\n      });\n      ```\n      This argument will become the model context of the linked route:\n    \n      ```handlebars\n      {{#link-to 'photoGallery.comment' aPhoto comment}}\n        {{comment.body}}\n      {{/link-to}}\n      ```\n    \n      ```html\n      <a href=\"/hamster-photos/42/comments/718\">\n        A+++ would snuggle again.\n      </a>\n      ```\n    \n      ### Supplying an explicit dynamic segment value\n      If you don't have a model object available to pass to `{{link-to}}`,\n      an optional string or integer argument can be passed for routes whose\n      paths contain dynamic segments. This argument will become the value\n      of the dynamic segment:\n    \n      ```javascript\n      Router.map(function() {\n        this.route(\"photoGallery\", { path: \"hamster-photos/:photo_id\" });\n      });\n      ```\n    \n      ```handlebars\n      {{#link-to 'photoGallery' aPhotoId}}\n        {{aPhoto.title}}\n      {{/link-to}}\n      ```\n    \n      ```html\n      <a href=\"/hamster-photos/42\">\n        Tomster\n      </a>\n      ```\n    \n      When transitioning into the linked route, the `model` hook will\n      be triggered with parameters including this passed identifier.\n    \n      ### Allowing Default Action\n    \n      By default the `{{link-to}}` component prevents the default browser action\n      by calling `preventDefault()` as this sort of action bubbling is normally\n      handled internally and we do not want to take the browser to a new URL (for\n      example).\n    \n      If you need to override this behavior specify `preventDefault=false` in\n      your template:\n    \n      ```handlebars\n      {{#link-to 'photoGallery' aPhotoId preventDefault=false}}\n        {{aPhotoId.title}}\n      {{/link-to}}\n      ```\n    \n      ### Overriding attributes\n      You can override any given property of the `LinkComponent`\n      that is generated by the `{{link-to}}` component by passing\n      key/value pairs, like so:\n    \n      ```handlebars\n      {{#link-to  aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}}\n        Uh-mazing!\n      {{/link-to}}\n      ```\n    \n      See [LinkComponent](/api/ember/release/classes/LinkComponent) for a\n      complete list of overrideable properties. Be sure to also\n      check out inherited properties of `LinkComponent`.\n    \n      ### Overriding Application-wide Defaults\n    \n      ``{{link-to}}`` creates an instance of `LinkComponent` for rendering. To\n      override options for your entire application, export your customized\n      `LinkComponent` from `app/components/link-to.js` with the desired overrides:\n    \n      ```javascript\n      // app/components/link-to.js\n      import LinkComponent from '@ember/routing/link-component';\n    \n      export default LinkComponent.extend({\n        activeClass: \"is-active\",\n        tagName: 'li'\n      })\n      ```\n    \n      It is also possible to override the default event in this manner:\n    \n      ```javascript\n      import LinkComponent from '@ember/routing/link-component';\n    \n      export default LinkComponent.extend({\n        eventName: 'customEventName'\n      });\n      ```\n    \n      @method link-to\n      @for Ember.Templates.helpers\n      @param {String} routeName\n      @param {Object} [context]*\n      @param [options] {Object} Handlebars key/value pairs of options, you can override any property of Ember.LinkComponent\n      @return {String} HTML string\n      @see {LinkComponent}\n      @public\n    */\n    const LinkComponent = _component.default.extend({\n        layout: _linkTo.default,\n        tagName: 'a',\n        /**\n          Used to determine when this `LinkComponent` is active.\n             @property current-when\n          @public\n        */\n        'current-when': null,\n        /**\n          Sets the `title` attribute of the `LinkComponent`'s HTML element.\n             @property title\n          @default null\n          @public\n        **/\n        title: null,\n        /**\n          Sets the `rel` attribute of the `LinkComponent`'s HTML element.\n             @property rel\n          @default null\n          @public\n        **/\n        rel: null,\n        /**\n          Sets the `tabindex` attribute of the `LinkComponent`'s HTML element.\n             @property tabindex\n          @default null\n          @public\n        **/\n        tabindex: null,\n        /**\n          Sets the `target` attribute of the `LinkComponent`'s HTML element.\n             @since 1.8.0\n          @property target\n          @default null\n          @public\n        **/\n        target: null,\n        /**\n          The CSS class to apply to `LinkComponent`'s element when its `active`\n          property is `true`.\n             @property activeClass\n          @type String\n          @default active\n          @public\n        **/\n        activeClass: 'active',\n        /**\n          The CSS class to apply to `LinkComponent`'s element when its `loading`\n          property is `true`.\n             @property loadingClass\n          @type String\n          @default loading\n          @private\n        **/\n        loadingClass: 'loading',\n        /**\n          The CSS class to apply to a `LinkComponent`'s element when its `disabled`\n          property is `true`.\n             @property disabledClass\n          @type String\n          @default disabled\n          @private\n        **/\n        disabledClass: 'disabled',\n        /**\n          Determines whether the `LinkComponent` will trigger routing via\n          the `replaceWith` routing strategy.\n             @property replace\n          @type Boolean\n          @default false\n          @public\n        **/\n        replace: false,\n        /**\n          By default the `{{link-to}}` component will bind to the `href` and\n          `title` attributes.

Type into\n    either text area box and they'll both stay in sync. Note that\n    `alias` costs more in terms of performance, so only use it when\n    your really binding in both directions:\n  \n    ```app/controllers/application.js\n    import Controller from '@ember/controller';\n    import { alias } from '@ember/object/computed';\n  \n    export default Controller.extend({\n      writtenWords: \"Lots of text that IS bound\",\n  \n      twoWayWrittenWords: alias(\"writtenWords\")\n    });\n    ```\n  \n    ```handlebars\n    {{textarea value=writtenWords}}\n    {{textarea value=twoWayWrittenWords}}\n    ```\n  \n    ```html\n    <textarea id=\"ember1\" class=\"ember-text-area\">\n      Lots of text that IS bound\n    </textarea>\n    <-- both updated in real time -->\n    <textarea id=\"ember2\" class=\"ember-text-area\">\n      Lots of text that IS bound\n    </textarea>\n    ```\n  \n    ### Actions\n  \n    The helper can send multiple actions based on user events.\n    The action property defines the action which is send when\n    the user presses the return key.\n  \n    ```handlebars\n    {{input action=\"submit\"}}\n    ```\n  \n    The helper allows some user events to send actions.\n  \n    * `enter`\n    * `insert-newline`\n    * `escape-press`\n    * `focus-in`\n    * `focus-out`\n    * `key-press`\n  \n    For example, if you desire an action to be sent when the input is blurred,\n    you only need to setup the action name to the event name property.\n  \n    ```handlebars\n    {{textarea focus-out=\"alertMessage\"}}\n    ```\n  \n    See more about [Text Support Actions](/api/ember/release/classes/TextArea)\n  \n    ### Extension\n  \n    Internally, `{{textarea}}` creates an instance of `TextArea`, passing\n    arguments from the helper to `TextArea`'s `create` method. You can\n    extend the capabilities of text areas in your application by reopening this\n    class. For example, if you are building a Bootstrap project where `data-*`\n    attributes are used, you can globally add support for a `data-*` attribute\n    on all `{{textarea}}`s' in your app by reopening `TextArea` or\n    `TextSupport` and adding it to the `attributeBindings` concatenated\n    property:\n  \n    ```javascript\n    import TextArea from '@ember/component/text-area';\n  \n    TextArea.reopen({\n      attributeBindings: ['data-error']\n    });\n    ```\n  \n    Keep in mind when writing `TextArea` subclasses that `TextArea`\n    itself extends `Component`.

The first two\n      contexts to discuss are attribute context, and Handlebars value context.\n    \n      ```handlebars\n      {{! An example of attribute context }}\n      <div onclick={{action \"save\"}}></div>\n      {{! Examples of Handlebars value context }}\n      {{input on-input=(action \"save\")}}\n      {{yield (action \"refreshData\") andAnotherParam}}\n      ```\n    \n      In these contexts,\n      the helper is called a \"closure action\" helper. Its behavior is simple:\n      If passed a function name, read that function off the `actions` property\n      of the current context. Once that function is read, or immediately if a function was\n      passed, create a closure over that function and any arguments.\n      The resulting value of an action helper used this way is simply a function.\n    \n      For example, in the attribute context:\n    \n      ```handlebars\n      {{! An example of attribute context }}\n      <div onclick={{action \"save\"}}></div>\n      ```\n    \n      The resulting template render logic would be:\n    \n      ```js\n      var div = document.createElement('div');\n      var actionFunction = (function(context){\n        return function() {\n          return context.actions.save.apply(context, arguments);\n        };\n      })(context);\n      div.onclick = actionFunction;\n      ```\n    \n      Thus when the div is clicked, the action on that context is called.\n      Because the `actionFunction` is just a function, closure actions can be\n      passed between components and still execute in the correct context.\n    \n      Here is an example action handler on a component:\n    \n      ```app/components/my-component.js\n      import Component from '@ember/component';\n    \n      export default Component.extend({\n        actions: {\n          save() {\n            this.get('model').save();\n          }\n        }\n      });\n      ```\n    \n      Actions are always looked up on the `actions` property of the current context.\n      This avoids collisions in the naming of common actions, such as `destroy`.\n      Two options can be passed to the `action` helper when it is used in this way.\n    \n      * `target=someProperty` will look to `someProperty` instead of the current\n        context for the `actions` hash. This can be useful when targeting a\n        service for actions.\n      * `value=\"target.value\"` will read the path `target.value` off the first\n        argument to the action when it is called and rewrite the first argument\n        to be that value. This is useful when attaching actions to event listeners.\n    \n      ### Invoking an action\n    \n      Closure actions curry both their scope and any arguments. When invoked, any\n      additional arguments are added to the already curried list.\n      Actions should be invoked using the [sendAction](/api/ember/release/classes/Component/methods/sendAction?anchor=sendAction)\n      method. The first argument to `sendAction` is the action to be called, and\n      additional arguments are passed to the action function. This has interesting\n      properties combined with currying of arguments. For example:\n    \n      ```app/components/my-component.js\n      import Component from '@ember/component';\n    \n      export default Component.extend({\n        actions: {\n          // Usage {{input on-input=(action (action 'setName' model) value=\"target.value\")}}\n          setName(model, name) {\n            model.set('name', name);\n          }\n        }\n      });\n      ```\n    \n      The first argument (`model`) was curried over, and the run-time argument (`event`)\n      becomes a second argument. Action calls can be nested this way because each simply\n      returns a function. Any function can be passed to the `{{action}}` helper, including\n      other actions.\n    \n      Actions invoked with `sendAction` have the same currying behavior as demonstrated\n      with `on-input` above. For example:\n    \n      ```app/components/my-input.js\n      import Component from '@ember/component';\n    \n      export default Component.extend({\n        actions: {\n          setName(model, name) {\n            model.set('name', name);\n          }\n        }\n      });\n      ```\n    \n      ```handlebars\n      {{my-input submit=(action 'setName' model)}}\n      ```\n    \n      ```app/components/my-component.js\n      import Component from '@ember/component';\n    \n      export default Component.extend({\n        click() {\n          // Note that model is not passed, it was curried in the template\n          this.sendAction('submit', 'bob');\n        }\n      });\n      ```\n    \n      ### Attaching actions to DOM elements\n    \n      The third context of the `{{action}}` helper can be called \"element space\".\n      For example:\n    \n      ```handlebars\n      {{! An example of element space }}\n      <div {{action \"save\"}}></div>\n      ```\n    \n      Used this way, the `{{action}}` helper provides a useful shortcut for\n      registering an HTML element in a template for a single DOM event and\n      forwarding that interaction to the template's context (controller or component).\n      If the context of a template is a controller, actions used this way will\n      bubble to routes when the controller does not implement the specified action.\n      Once an action hits a route, it will bubble through the route hierarchy.\n    \n      ### Event Propagation\n    \n      `{{action}}` helpers called in element space can control event bubbling. Note\n      that the closure style actions cannot.\n    \n      Events triggered through the action helper will automatically have\n      `.preventDefault()` called on them. You do not need to do so in your event\n      handlers. If you need to allow event propagation (to handle file inputs for\n      example) you can supply the `preventDefault=false` option to the `{{action}}` helper:\n    \n      ```handlebars\n      <div {{action \"sayHello\" preventDefault=false}}>\n        <input type=\"file\" />\n        <input type=\"checkbox\" />\n      </div>\n      ```\n    \n      To disable bubbling, pass `bubbles=false` to the helper:\n    \n      ```handlebars\n      <button {{action 'edit' post bubbles=false}}>Edit</button>\n      ```\n    \n      To disable bubbling with closure style actions you must create your own\n      wrapper helper that makes use of `event.stopPropagation()`:\n    \n      ```handlebars\n      <div onclick={{disable-bubbling (action \"sayHello\")}}>Hello</div>\n      ```\n    \n      ```app/helpers/disable-bubbling.js\n      import { helper } from '@ember/component/helper';\n    \n      export function disableBubbling([action]) {\n        return function(event) {\n          event.stopPropagation();\n          return action(event);\n        };\n      }\n      export default helper(disableBubbling);\n      ```\n    \n      If you need the default handler to trigger you should either register your\n      own event handler, or use event methods on your view class. See\n      [\"Responding to Browser Events\"](/api/ember/release/classes/Component)\n      in the documentation for `Component` for more information.\n    \n      ### Specifying DOM event type\n    \n      `{{action}}` helpers called in element space can specify an event type.\n      By default the `{{action}}` helper registers for DOM `click` events. You can\n      supply an `on` option to the helper to specify a different DOM event name:\n    \n      ```handlebars\n      <div {{action \"anActionName\" on=\"doubleClick\"}}>\n        click me\n      </div>\n      ```\n    \n      See [\"Event Names\"](/api/ember/release/classes/Component) for a list of\n      acceptable DOM event names.\n    \n      ### Specifying whitelisted modifier keys\n    \n      `{{action}}` helpers called in element space can specify modifier keys.\n      By default the `{{action}}` helper will ignore click events with pressed modifier\n      keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.\n    \n      ```handlebars\n      <div {{action \"anActionName\" allowedKeys=\"alt\"}}>\n        click me\n      </div>\n      ```\n    \n      This way the action will fire when clicking with the alt key pressed down.\n      Alternatively, supply \"any\" to the `allowedKeys` option to accept any combination of modifier keys.\n    \n      ```handlebars\n      <div {{action \"anActionName\" allowedKeys=\"any\"}}>\n        click me with any key pressed\n      </div>\n      ```\n    \n      ### Specifying a Target\n    \n      A `target` option can be provided to the helper to change\n      which object will receive the method call. This option must be a path\n      to an object, accessible in the current context:\n    \n      ```app/templates/application.hbs\n      <div {{action \"anActionName\" target=someService}}>\n        click me\n      </div>\n      ```\n    \n      ```app/controllers/application.js\n      import Controller from '@ember/controller';\n      import { inject as service } from '@ember/service';\n    \n      export default Controller.extend({\n        someService: service()\n      });\n      ```\n    \n      @method action\n      @for Ember.Templates.helpers\n      @public\n    */\n\n    function makeArgsProcessor(valuePathRef, actionArgsRef) {\n        let mergeArgs;\n        if (actionArgsRef.length > 0) {\n            mergeArgs = args => {\n                return actionArgsRef.map(ref => ref.value()).concat(args);\n            };\n        }\n        let readValue;\n        if (valuePathRef) {\n            readValue = args => {\n                let valuePath = valuePathRef.value();\n                if (valuePath && args.length > 0) {\n                    args[0] = (0, _metal.get)(args[0], valuePath);\n                }\n                return args;\n            };\n        }\n        if (mergeArgs && readValue) {\n            return args => {\n                return readValue(mergeArgs(args));\n            };\n        } else {\n            return mergeArgs || readValue || NOOP;\n        }\n    }\n    function makeDynamicClosureAction(context, targetRef, actionRef, processArgs, debugKey) {\n        // We don't allow undefined/null values, so this creates a throw-away action to trigger the assertions\n        if (_env.DEBUG) {\n            makeClosureAction(context, targetRef.value(), actionRef.value(), processArgs, debugKey);\n        }\n        return (...args) => {\n            return makeClosureAction(context, targetRef.value(), actionRef.value(), processArgs, debugKey)(...args);\n        };\n    }\n    function makeClosureAction(context, target, action, processArgs, debugKey) {\n        let self;\n        let fn;\n        (0, _debug.assert)(`Action passed is null or undefined in (action) from ${target}.`, action !== undefined && action !== null);\n        if (typeof action[_references.INVOKE] === 'function') {\n            self = action;\n            fn = action[_references.INVOKE];\n        } else {\n            let typeofAction = typeof action;\n            if (typeofAction === 'string') {\n                self = target;\n                fn = target.actions && target.actions[action];\n                (0, _debug.assert)(`An action named '${action}' was not found in ${target}`, fn);\n            } else if (typeofAction === 'function') {\n                self = context;\n                fn = action;\n            } else {\n                // tslint:disable-next-line:max-line-length\n                (0, _debug.assert)(`An action could not be made for \\`${debugKey || action}\\` in ${target}.

See [Component](/api/ember/release/classes/Component) for\n    additional information on how a `Component` functions.\n    `{{component}}`'s primary use is for cases where you want to dynamically\n    change which type of component is rendered as the state of your application\n    changes. This helper has three modes: inline, block, and nested.\n  \n    ### Inline Form\n  \n    Given the following template:\n  \n    ```app/application.hbs\n    {{component infographicComponentName}}\n    ```\n  \n    And the following application code:\n  \n    ```app/controllers/application.js\n    import Controller from '@ember/controller';\n    import { computed } from '@ember/object';\n  \n    export default Controller.extend({\n      infographicComponentName: computed('isMarketOpen', {\n        get() {\n          if (this.get('isMarketOpen')) {\n            return 'live-updating-chart';\n          } else {\n            return 'market-close-summary';\n          }\n        }\n      })\n    });\n    ```\n  \n    The `live-updating-chart` component will be appended when `isMarketOpen` is\n    `true`, and the `market-close-summary` component will be appended when\n    `isMarketOpen` is `false`. If the value changes while the app is running,\n    the component will be automatically swapped out accordingly.\n    Note: You should not use this helper when you are consistently rendering the same\n    component. In that case, use standard component syntax, for example:\n  \n    ```app/templates/application.hbs\n    {{live-updating-chart}}\n    ```\n  \n    ### Block Form\n  \n    Using the block form of this helper is similar to using the block form\n    of a component. Given the following application template:\n  \n    ```app/templates/application.hbs\n    {{#component infographicComponentName}}\n      Last update: {{lastUpdateTimestamp}}\n    {{/component}}\n    ```\n  \n    The following controller code:\n  \n    ```app/controllers/application.js\n    import Controller from '@ember/controller';\n    import { computed } from '@ember/object';\n  \n    export default Controller.extend({\n      lastUpdateTimestamp: computed(function() {\n        return new Date();\n      }),\n  \n      infographicComponentName: computed('isMarketOpen', {\n        get() {\n          if (this.get('isMarketOpen')) {\n            return 'live-updating-chart';\n          } else {\n            return 'market-close-summary';\n          }\n        }\n      })\n    });\n    ```\n  \n    And the following component template:\n  \n    ```app/templates/components/live-updating-chart.hbs\n    {{! chart }}\n    {{yield}}\n    ```\n  \n    The `Last Update: {{lastUpdateTimestamp}}` will be rendered in place of the `{{yield}}`.\n  \n    ### Nested Usage\n  \n    The `component` helper can be used to package a component path with initial attrs.\n    The included attrs can then be merged during the final invocation.\n    For example, given a `person-form` component with the following template:\n  \n    ```app/templates/components/person-form.hbs\n    {{yield (hash\n      nameInput=(component \"my-input-component\" value=model.name placeholder=\"First Name\")\n    )}}\n    ```\n  \n    When yielding the component via the `hash` helper, the component is invoked directly.\n    See the following snippet:\n  \n    ```\n    {{#person-form as |form|}}\n      {{form.nameInput placeholder=\"Username\"}}\n    {{/person-form}}\n    ```\n  \n    Which outputs an input whose value is already bound to `model.name` and `placeholder`\n    is \"Username\".\n  \n    When yielding the component without the hash helper use the `component` helper.\n    For example, below is a `full-name` component template:\n  \n    ```handlebars\n    {{yield (component \"my-input-component\" value=model.name placeholder=\"Name\")}}\n    ```\n  \n    ```\n    {{#full-name as |field|}}\n      {{component field placeholder=\"Full name\"}}\n    {{/full-name}}\n    ```\n  \n    @method component\n    @since 1.11.0\n    @for Ember.Templates.helpers\n    @public\n  */\n});","enifed('@ember/-internals/glimmer/lib/helpers/concat', ['exports', '@ember/-internals/glimmer/lib/utils/references'], function (exports, _references) {\n    'use strict';\n\n    exports.__esModule = true;\n\n    exports.default = function (_vm, args) {\n        return new _references.InternalHelperReference(concat, args.capture());\n    };\n\n    const isEmpty = value => {\n        return value === null || value === undefined || typeof value.toString !== 'function';\n    };\n    const normalizeTextValue = value => {\n        if (isEmpty(value)) {\n            return '';\n        }\n        return String(value);\n    };\n    /**\n    @module ember\n    */\n    /**\n      Concatenates the given arguments into a string.\n    \n      Example:\n    \n      ```handlebars\n      {{some-component name=(concat firstName \" \" lastName)}}\n    \n      {{! would pass name=\"<first name value> <last name value>\" to the component}}\n      ```\n    \n      @public\n      @method concat\n      @for Ember.Templates.helpers\n      @since 1.13.0\n    */\n    function concat({ positional }) {\n        return positional.value().map(normalizeTextValue).join('');\n    }\n});","enifed('@ember/-internals/glimmer/lib/helpers/each-in', ['exports', '@ember/-internals/utils'], function (exports, _utils) {\n  'use strict';\n\n  exports.__esModule = true;\n  exports.isEachIn = isEachIn;\n\n  exports.default = function (_vm, args) {\n    return new EachInReference(args.positional.at(0));\n  };\n\n  /**\n    The `{{#each}}` helper loops over elements in a collection. It is an extension\n    of the base Handlebars `{{#each}}` helper.\n    The default behavior of `{{#each}}` is to yield its inner block once for every\n    item in an array passing the item as the first block parameter.\n  \n    ```javascript\n    var developers = [{ name: 'Yehuda' },{ name: 'Tom' }, { name: 'Paul' }];\n    ```\n  \n    ```handlebars\n    {{#each developers key=\"name\" as |person|}}\n      {{person.name}}\n      {{! `this` is whatever it was outside the #each }}\n    {{/each}}\n    ```\n  \n    The same rules apply to arrays of primitives.\n  \n    ```javascript\n    var developerNames = ['Yehuda', 'Tom', 'Paul']\n    ```\n  \n    ```handlebars\n    {{#each developerNames key=\"@index\" as |name|}}\n      {{name}}\n    {{/each}}\n    ```\n  \n    During iteration, the index of each item in the array is provided as a second block parameter.\n  \n    ```handlebars\n    <ul>\n      {{#each people as |person index|}}\n        <li>Hello, {{person.name}}! You're number {{index}} in line</li>\n      {{/each}}\n    </ul>\n    ```\n  \n    ### Specifying Keys\n  \n    The `key` option is used to tell Ember how to determine if the array being\n    iterated over with `{{#each}}` has changed between renders. By helping Ember\n    detect that some elements in the array are the same, DOM elements can be\n    re-used, significantly improving rendering speed.\n  \n    For example, here's the `{{#each}}` helper with its `key` set to `id`:\n  \n    ```handlebars\n    {{#each model key=\"id\" as |item|}}\n    {{/each}}\n    ```\n  \n    When this `{{#each}}` re-renders, Ember will match up the previously rendered\n    items (and reorder the generated DOM elements) based on each item's `id`\n    property.\n    By default the item's own reference is used.\n  \n    ### {{else}} condition\n  \n    `{{#each}}` can have a matching `{{else}}`. The contents of this block will render\n    if the collection is empty.\n  \n    ```handlebars\n    {{#each developers as |person|}}\n      {{person.name}}\n    {{else}}\n      <p>Sorry, nobody is available for this task.</p>\n    {{/each}}\n    ```\n  \n    @method each\n    @for Ember.Templates.helpers\n    @public\n   */\n  /**\n    The `{{each-in}}` helper loops over properties on an object.\n  \n    For example, given a `user` object that looks like:\n  \n    ```javascript\n    {\n      \"name\": \"Shelly Sails\",\n      \"age\": 42\n    }\n    ```\n  \n    This template would display all properties on the `user`\n    object in a list:\n  \n    ```handlebars\n    <ul>\n    {{#each-in user as |key value|}}\n      <li>{{key}}: {{value}}</li>\n    {{/each-in}}\n    </ul>\n    ```\n  \n    Outputting their name and age.\n  \n    @method each-in\n    @for Ember.Templates.helpers\n    @public\n    @since 2.1.0\n  */\n  const EACH_IN_REFERENCE = (0, _utils.symbol)('EACH_IN'); /**\n                                                           @module ember\n                                                           */\n\n  class EachInReference {\n    constructor(inner) {\n      this.inner = inner;\n      this.tag = inner.tag;\n      this[EACH_IN_REFERENCE] = true;\n    }\n    value() {\n      return this.inner.value();\n    }\n    get(key) {\n      return this.inner.get(key);\n    }\n  }\n  function isEachIn(ref) {\n    return ref !== null && typeof ref === 'object' && ref[EACH_IN_REFERENCE];\n  }\n});","enifed('@ember/-internals/glimmer/lib/helpers/get', ['exports', '@ember/-internals/metal', '@glimmer/reference', '@glimmer/runtime', '@ember/-internals/glimmer/lib/utils/references'], function (exports, _metal, _reference, _runtime, _references) {\n    'use strict';\n\n    exports.__esModule = true;\n\n    exports.default = function (_vm, args) {\n        return GetHelperReference.create(args.positional.at(0), args.positional.at(1));\n    };\n\n    function referenceFromPath(source, path) {\n        let innerReference;\n        if (path === undefined || path === null || path === '') {\n            innerReference = _runtime.NULL_REFERENCE;\n        } else if (typeof path === 'string' && path.indexOf('.') > -1) {\n            innerReference = (0, _references.referenceFromParts)(source, path.split('.'));\n        } else {\n            innerReference = source.get(path);\n        }\n        return innerReference;\n    }\n    /**\n    @module ember\n    */\n    /**\n      Dynamically look up a property on an object.

For more info,\n      see the [TextField](/api/ember/release/classes/TextField) docs and\n      the [templates guide](https://guides.emberjs.com/release/templates/input-helpers/).\n    \n      ```handlebars\n      {{input value=\"987\"}}\n      ```\n    \n      renders as:\n    \n      ```HTML\n      <input type=\"text\" value=\"987\" />\n      ```\n    \n      ### Text field\n    \n      If no `type` option is specified, a default of type 'text' is used.\n      Many of the standard HTML attributes may be passed to this helper.\n      <table>\n        <tr><td>`readonly`</td><td>`required`</td><td>`autofocus`</td></tr>\n        <tr><td>`value`</td><td>`placeholder`</td><td>`disabled`</td></tr>\n        <tr><td>`size`</td><td>`tabindex`</td><td>`maxlength`</td></tr>\n        <tr><td>`name`</td><td>`min`</td><td>`max`</td></tr>\n        <tr><td>`pattern`</td><td>`accept`</td><td>`autocomplete`</td></tr>\n        <tr><td>`autosave`</td><td>`formaction`</td><td>`formenctype`</td></tr>\n        <tr><td>`formmethod`</td><td>`formnovalidate`</td><td>`formtarget`</td></tr>\n        <tr><td>`height`</td><td>`inputmode`</td><td>`multiple`</td></tr>\n        <tr><td>`step`</td><td>`width`</td><td>`form`</td></tr>\n        <tr><td>`selectionDirection`</td><td>`spellcheck`</td><td>&nbsp;</td></tr>\n      </table>\n      When set to a quoted string, these values will be directly applied to the HTML\n      element. When left unquoted, these values will be bound to a property on the\n      template's current rendering context (most typically a controller instance).\n      A very common use of this helper is to bind the `value` of an input to an Object's attribute:\n    \n      ```handlebars\n      Search:\n      {{input value=searchWord}}\n      ```\n    \n      In this example, the initial value in the `<input />` will be set to the value of `searchWord`.\n      If the user changes the text, the value of `searchWord` will also be updated.\n    \n      ### Actions\n    \n      The helper can send multiple actions based on user events.\n      The action property defines the action which is sent when\n      the user presses the return key.\n    \n      ```handlebars\n      {{input action=\"submit\"}}\n      ```\n    \n      The helper allows some user events to send actions.\n    \n      * `enter`\n      * `insert-newline`\n      * `escape-press`\n      * `focus-in`\n      * `focus-out`\n      * `key-press`\n      * `key-up`\n    \n      For example, if you desire an action to be sent when the input is blurred,\n      you only need to setup the action name to the event name property.\n    \n      ```handlebars\n      {{input focus-out=\"alertMessage\"}}\n      ```\n      See more about [Text Support Actions](/api/ember/release/classes/TextField)\n    \n      ### Extending `TextField`\n    \n      Internally, `{{input type=\"text\"}}` creates an instance of `TextField`, passing\n      arguments from the helper to `TextField`'s `create` method. You can extend the\n      capabilities of text inputs in your applications by reopening this class. For example,\n      if you are building a Bootstrap project where `data-*` attributes are used, you\n      can add one to the `TextField`'s `attributeBindings` property:\n    \n      ```javascript\n      import TextField from '@ember/component/text-field';\n      TextField.reopen({\n        attributeBindings: ['data-error']\n      });\n      ```\n    \n      Keep in mind when writing `TextField` subclasses that `TextField`\n      itself extends `Component`. Expect isolated component semantics, not\n      legacy 1.x view semantics (like `controller` being present).\n      See more about [Ember components](/api/ember/release/classes/Component)\n    \n      ### Checkbox\n    \n      Checkboxes are special forms of the `{{input}}` helper.  To create a `<checkbox />`:\n    \n      ```handlebars\n      Emberize Everything:\n      {{input type=\"checkbox\" name=\"isEmberized\" checked=isEmberized}}\n      ```\n    \n      This will bind checked state of this checkbox to the value of `isEmberized`  -- if either one changes,\n      it will be reflected in the other.\n    \n      The following HTML attributes can be set via the helper:\n    \n      * `checked`\n      * `disabled`\n      * `tabindex`\n      * `indeterminate`\n      * `name`\n      * `autofocus`\n      * `form`\n    \n      ### Extending `Checkbox`\n    \n      Internally, `{{input type=\"checkbox\"}}` creates an instance of `Checkbox`, passing\n      arguments from the helper to `Checkbox`'s `create` method. You can extend the\n      capablilties of checkbox inputs in your applications by reopening this class. For example,\n      if you wanted to add a css class to all checkboxes in your application:\n    \n      ```javascript\n      import Checkbox from '@ember/component/checkbox';\n    \n      Checkbox.reopen({\n        classNames: ['my-app-checkbox']\n      });\n      ```\n    \n      @method input\n      @for Ember.Templates.helpers\n      @param {Hash} options\n      @public\n    */\n    function inputMacro(_name, params, hash, builder) {\n        if (params === null) {\n            params = [];\n        }\n        if (hash !== null) {\n            let keys = hash[0];\n            let values = hash[1];\n            let typeIndex = keys.indexOf('type');\n            if (typeIndex > -1) {\n                let typeArg = values[typeIndex];\n                if (Array.isArray(typeArg)) {\n                    // there is an AST plugin that converts this to an expression\n                    // it really should just compile in the component call too.\n                    let inputTypeExpr = params[0];\n                    builder.dynamicComponent(inputTypeExpr, null, params.slice(1), hash, true, null, null);\n                    return true;\n                }\n                if (typeArg === 'checkbox') {\n                    (0, _debug.assert)(\"{{input type='checkbox'}} does not support setting `value=someBooleanValue`; \" + 'you must use `checked=someBooleanValue` instead.', keys.indexOf('value') === -1);\n                    (0, _bindings.wrapComponentClassAttribute)(hash);\n                    return buildSyntax('-checkbox', params, hash, builder);\n                }\n            }\n        }\n        return buildSyntax('-text-field', params, hash, builder);\n    }\n});","enifed(\"@ember/-internals/glimmer/lib/syntax/let\", [\"exports\"], function (exports) {\n    \"use strict\";\n\n    exports.__esModule = true;\n    exports.blockLetMacro = blockLetMacro;\n    /**\n    @module ember\n    */\n    /**\n        The `let` helper receives one or more positional arguments and yields\n        them out as block params.\n    \n        This allows the developer to introduce shorter names for certain computations\n        in the template.\n    \n        This is especially useful if you are passing properties to a component\n        that receives a lot of options and you want to clean up the invocation.\n    \n        For the following example, the template receives a `post` object with\n        `content` and `title` properties.\n    \n        We are going to call the `my-post` component, passing a title which is\n        the title of the post suffixed with the name of the blog, the content\n        of the post, and a series of options defined in-place.\n    \n        ```handlebars\n        {{#let\n            (concat post.title ' | The Ember.js Blog')\n            post.content\n            (hash\n              theme=\"high-contrast\"\n              enableComments=true\n            )\n            as |title content options|\n        }}\n          {{my-post title=title content=content options=options}}\n        {{/let}}\n      ```\n    \n      @method let\n      @for Ember.Templates.helpers\n      @public\n    */\n    function blockLetMacro(params, _hash, template, _inverse, builder) {\n        if (template !== null) {\n            if (params !== null) {\n                builder.compileParams(params);\n                builder.invokeStaticBlock(template, params.length);\n            } else {\n                builder.invokeStatic(template);\n            }\n        }\n        return true;\n    }\n});","enifed('@ember/-internals/glimmer/lib/syntax/mount', ['exports', '@ember/canary-features', '@ember/debug', '@glimmer/runtime', '@glimmer/wire-format', '@ember/-internals/glimmer/lib/component-managers/mount'], function (exports, _canaryFeatures, _debug, _runtime, _wireFormat, _mount) {\n    'use strict';\n\n    exports.__esModule = true;\n    exports.mountHelper = mountHelper;\n    exports.mountMacro = mountMacro;\n    function mountHelper(vm, args) {\n        let env = vm.env;\n        let nameRef = args.positional.at(0);\n        let modelRef = args.named.has('model') ? args.named.get('model') : undefined;\n        return new DynamicEngineReference(nameRef, env, modelRef);\n    }\n    /**\n      The `{{mount}}` helper lets you embed a routeless engine in a template.\n      Mounting an engine will cause an instance to be booted and its `application`\n      template to be rendered.\n    \n      For example, the following template mounts the `ember-chat` engine:\n    \n      ```handlebars\n      {{! application.hbs }}\n      {{mount \"ember-chat\"}}\n      ```\n    \n      Additionally, you can also pass in a `model` argument that will be\n      set as the engines model.

property will only be called\n      once and the result will be cached. You can specify various properties\n      that your computed property depends on. This will force the cached\n      result to be recomputed if the dependencies are modified.\n    \n      In the following example we declare a computed property - `fullName` - by calling\n      `computed` with property dependencies (`firstName` and `lastName`) as leading arguments and getter accessor function. The `fullName` getter function\n      will be called once (regardless of how many times it is accessed) as long\n      as its dependencies have not changed. Once `firstName` or `lastName` are updated\n      any future calls (or anything bound) to `fullName` will incorporate the new\n      values.\n    \n      ```javascript\n      import EmberObject, { computed } from '@ember/object';\n    \n      let Person = EmberObject.extend({\n        // these will be supplied by `create`\n        firstName: null,\n        lastName: null,\n    \n        fullName: computed('firstName', 'lastName', function() {\n          let firstName = this.get('firstName'),\n              lastName  = this.get('lastName');\n    \n          return `${firstName} ${lastName}`;\n        })\n      });\n    \n      let tom = Person.create({\n        firstName: 'Tom',\n        lastName: 'Dale'\n      });\n    \n      tom.get('fullName') // 'Tom Dale'\n      ```\n    \n      You can also define what Ember should do when setting a computed property by providing additional function (`set`) in hash argument.\n      If you try to set a computed property, it will try to invoke setter accessor function with the key and\n      value you want to set it to as arguments.\n    \n      ```javascript\n      import EmberObject, { computed } from '@ember/object';\n    \n      let Person = EmberObject.extend({\n        // these will be supplied by `create`\n        firstName: null,\n        lastName: null,\n    \n        fullName: computed('firstName', 'lastName', {\n          get(key) {\n            let firstName = this.get('firstName'),\n                lastName  = this.get('lastName');\n    \n            return firstName + ' ' + lastName;\n          },\n          set(key, value) {\n            let [firstName, lastName] = value.split(' ');\n    \n            this.set('firstName', firstName);\n            this.set('lastName', lastName);\n    \n            return value;\n          }\n        })\n      });\n    \n      let person = Person.create();\n    \n      person.set('fullName', 'Peter Wagenet');\n      person.get('firstName'); // 'Peter'\n      person.get('lastName');  // 'Wagenet'\n      ```\n    \n      You can overwrite computed property with normal property (no longer computed), that won't change if dependencies change, if you set computed property and it won't have setter accessor function defined.\n    \n      You can also mark computed property as `.readOnly()` and block all attempts to set it.\n    \n      ```javascript\n      import EmberObject, { computed } from '@ember/object';\n    \n      let Person = EmberObject.extend({\n        // these will be supplied by `create`\n        firstName: null,\n        lastName: null,\n    \n        fullName: computed('firstName', 'lastName', {\n          get(key) {\n            let firstName = this.get('firstName');\n            let lastName  = this.get('lastName');\n    \n            return firstName + ' ' + lastName;\n          }\n        }).readOnly()\n      });\n    \n      let person = Person.create();\n      person.set('fullName', 'Peter Wagenet'); // Uncaught Error: Cannot set read-only property \"fullName\" on object: <(...):emberXXX>\n      ```\n    \n      Additional resources:\n      - [New CP syntax RFC](https://github.com/emberjs/rfcs/blob/master/text/0011-improved-cp-syntax.md)\n      - [New computed syntax explained in \"Ember 1.12 released\" ](https://emberjs.com/blog/2015/05/13/ember-1-12-released.html#toc_new-computed-syntax)\n    \n      @class ComputedProperty\n      @public\n    */\n    class ComputedProperty extends _properties.Descriptor {\n        constructor(config, opts) {\n            super();\n            let hasGetterOnly = typeof config === 'function';\n            if (hasGetterOnly) {\n                this._getter = config;\n            } else {\n                const objectConfig = config;\n                (0, _debug.assert)('computed expects a function or an object as last argument.', typeof objectConfig === 'object' && !Array.isArray(objectConfig));\n                (0, _debug.assert)('Config object passed to computed can only contain `get` and `set` keys.', Object.keys(objectConfig).every(key => key === 'get' || key === 'set'));\n                (0, _debug.assert)('Computed properties must receive a getter or a setter, you passed none.', !!objectConfig.get || !!objectConfig.set);\n                this._getter = objectConfig.get || noop;\n                this._setter = objectConfig.set;\n            }\n            this._suspended = undefined;\n            this._meta = undefined;\n            this._volatile = false;\n            if (_canaryFeatures.EMBER_METAL_TRACKED_PROPERTIES) {\n                this._auto = false;\n            }\n            this._dependentKeys = opts && opts.dependentKeys;\n            this._readOnly = !!opts && hasGetterOnly && opts.readOnly === true;\n        }\n        /**\n          Call on a computed property to set it into non-cached mode.

For\n        example, in the above example, the `fullName` property depends on\n        `firstName` and `lastName` to determine its value. You can tell Ember\n        about these dependencies like this:\n         ```app/utils/president.js\n        import EmberObject from '@ember/object';\n         export default EmberObject.extend({\n          firstName: '',\n          lastName:  '',\n           fullName: function() {\n            return this.get('firstName') + ' ' + this.get('lastName');\n             // Tell Ember.js that this computed property depends on firstName\n            // and lastName\n          }.property('firstName', 'lastName')\n        });\n        ```\n         Make sure you list these dependencies so Ember knows when to update\n        bindings that connect to a computed property. Changing a dependency\n        will not immediately trigger an update of the computed property, but\n        will instead clear the cache so that it is updated when the next `get`\n        is called on the property.\n         See [ComputedProperty](/api/ember/release/classes/ComputedProperty), [@ember/object/computed](/api/ember/release/classes/@ember%2Fobject%2Fcomputed).\n         @method property\n        @for Function\n        @public\n      */\n      property: {\n        configurable: true,\n        enumerable: false,\n        writable: true,\n        value: function () {\n          return (0, _metal.computed)(...arguments, this);\n        }\n      },\n\n      /**\n        The `observes` extension of Javascript's Function prototype is available\n        when `EmberENV.EXTEND_PROTOTYPES` or `EmberENV.EXTEND_PROTOTYPES.Function` is\n        true, which is the default.\n         You can observe property changes simply by adding the `observes`\n        call to the end of your method declarations in classes that you write.\n        For example:\n         ```javascript\n        import EmberObject from '@ember/object';\n         EmberObject.extend({\n          valueObserver: function() {\n            // Executes whenever the \"value\" property changes\n          }.observes('value')\n        });\n        ```\n         In the future this method may become asynchronous.\n         See `observer`.\n         @method observes\n        @for Function\n        @public\n      */\n      observes: {\n        configurable: true,\n        enumerable: false,\n        writable: true,\n        value: function () {\n          return (0, _metal.observer)(...arguments, this);\n        }\n      },\n\n      /**\n        The `on` extension of Javascript's Function prototype is available\n        when `EmberENV.EXTEND_PROTOTYPES` or `EmberENV.EXTEND_PROTOTYPES.Function` is\n        true, which is the default.\n         You can listen for events simply by adding the `on` call to the end of\n        your method declarations in classes or mixins that you write.

actions hash is merged rather\n      // then replaced when extending mixins / parent classes.\n      this.send('displayBanner');\n      this.send('playMusic');\n      ```\n       Within a Controller, Route or Component's action handler,\n      the value of the `this` context is the Controller, Route or\n      Component object:\n       ```app/routes/song.js\n      import Route from '@ember/routing/route';\n       export default Route.extend({\n        actions: {\n          myAction() {\n            this.controllerFor(\"song\");\n            this.transitionTo(\"other.route\");\n            ...\n          }\n        }\n      });\n      ```\n       It is also possible to call `this._super(...arguments)` from within an\n      action handler if it overrides a handler defined on a parent\n      class or mixin:\n       Take for example the following routes:\n       ```app/mixins/debug-route.js\n      import Mixin from '@ember/mixin';\n       export default Mixin.create({\n        actions: {\n          debugRouteInformation() {\n            console.debug(\"It's a-me, console.debug!\");\n          }\n        }\n      });\n      ```\n       ```app/routes/annoying-debug.js\n

window.alert(...);\n          }\n        }\n      });\n      ```\n       ## Bubbling\n       By default, an action will stop bubbling once a handler defined\n      on the `actions` hash handles it. To continue bubbling the action,\n      you must return `true` from the handler:\n       ```app/router.js\n      Router.map(function() {\n        this.route(\"album\", function() {\n          this.route(\"song\");\n        });\n      });\n      ```\n       ```app/routes/album.js\n      import Route from '@ember/routing/route';\n       export default Route.extend({\n        actions: {\n          startPlaying: function() {\n          }\n        }\n      });\n      ```\n       ```app/routes/album-song.js\n      import Route from '@ember/routing/route';\n       export default Route.extend({\n        actions: {\n          startPlaying() {\n            // ...\n             if (actionShouldAlsoBeTriggeredOnParentRoute) {\n              return true;\n            }\n          }\n        }\n      });\n      ```\n       @property actions\n      @type Object\n      @default null\n      @public\n    */\n\n    /**\n      Triggers a named action on the `ActionHandler`.

This is useful for those times when you need to\n      implement a property that is composed of one or more member\n      properties.\n       ### Unknown Properties\n       If you try to set a value on a key that is undefined in the target\n      object, then the `setUnknownProperty()` handler will be called instead. This\n      gives you an opportunity to implement complex \"virtual\" properties that\n      are not predefined on the object.

Since\n      it changes expectations about behavior of properties, you should properly\n      document its usage in each individual merged property (to not\n      mislead your users to think they can override the property in a subclass).\n       @property mergedProperties\n      @type Array\n      @default null\n      @public\n    */\n\n    /**\n      Destroyed object property flag.\n       if this property is `true` the observers and bindings were already\n      removed by the effect of calling the `destroy()` method.\n       @property isDestroyed\n      @default false\n      @public\n    */\n    get isDestroyed() {\n      return (0, _meta.peekMeta)(this).isSourceDestroyed();\n    }\n\n    set isDestroyed(value) {\n      (0, _debug.assert)(`You cannot set \\`${this}.isDestroyed\\` directly, please use \\`.destroy()\\`.`, false);\n    }\n\n    /**\n      Destruction scheduled flag.

Any instance\n      of the `Person` class will *not* have the `march()` method.\n       You can also pass `Mixin` classes to add additional properties to the subclass.\n       ```javascript\n      import EmberObject from '@ember/object';\n      import Mixin from '@ember/object/mixin';\n       const Person = EmberObject.extend({\n        say(thing) {\n          alert(`${this.get('name')} says: ${thing}`);\n        }\n      });\n       const SingingMixin = Mixin.create({\n        sing(thing) {\n          alert(`${this.get('name')} sings: la la la ${thing}`);\n        }\n      });\n       const BroadwayStar = Person.extend(SingingMixin, {\n        dance() {\n          alert(`${this.get('name')} dances: tap tap tap tap `);\n        }\n      });\n      ```\n       The `BroadwayStar` class contains three methods: `say()`, `sing()`, and `dance()`.\n       @method extend\n      @static\n      @for @ember/object\n      @param {Mixin} [mixins]* One or more Mixin classes\n      @param {Object} [arguments]* Object containing values to use within the new class\n      @public\n    */\n    static extend() {\n      let Class = class extends this {};\n      reopen.apply(Class.PrototypeMixin, arguments);\n      return Class;\n    }\n\n    /**\n      Creates an instance of a class.

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

While the code above would work fine on\n      the initial boot (i.e. DOM ready), when `App.reset()` is called, we need to\n      boot a new instance synchronously (see the documentation on `_bootSync()`\n      for details).\n       Because of this restriction, the actual logic of this method is located\n      inside `didBecomeReady()`.\n       @private\n      @method domReady\n    */\n    domReady() {\n      if (this.isDestroyed) {\n        return;\n      }\n\n      this._bootSync();\n\n      // Continues to `didBecomeReady`\n    },\n\n    /**\n      Use this to defer readiness until some condition is true.\n       Example:\n       ```javascript\n      import Application from '@ember/application';\n       let App = Application.create();\n       App.deferReadiness();\n       // $ is a reference to the jQuery object/function\n      import $ from 'jquery;\n       $.getJSON('/auth-token', function(token) {\n        App.token = token;\n        App.advanceReadiness();\n      });\n      ```\n       This allows you to perform asynchronous setup logic and defer\n      booting your application until the setup has finished.\n       However, if the setup requires a loading UI, it might be better\n      to use the router for this purpose.\n       @method deferReadiness\n      @public\n    */\n    deferReadiness() {\n      (0, _debug.assert)('You must call deferReadiness on an instance of Application', this instanceof Application);\n      (0, _debug.assert)('You cannot defer readiness since the `ready()` hook has already been called.', this._readinessDeferrals > 0);\n      this._readinessDeferrals++;\n    },\n\n    /**\n      Call `advanceReadiness` after any asynchronous setup logic has completed.\n      Each call to `deferReadiness` must be matched by a call to `advanceReadiness`\n      or the application will never become ready and routing will not begin.\n       @method advanceReadiness\n      @see {Application#deferReadiness}\n      @public\n    */\n    advanceReadiness() {\n      (0, _debug.assert)('You must call advanceReadiness on an instance of Application', this instanceof Application);\n      this._readinessDeferrals--;\n\n      if (this._readinessDeferrals === 0) {\n        (0, _runloop.once)(this, this.didBecomeReady);\n      }\n    },\n\n    /**\n      Initialize the application and return a promise that resolves with the `Application`\n      object when the boot process is complete.\n       Run any application initializers and run the application load hook.

See the documentation on\n      `ApplicationInstance.BootOptions` for details.\n       `ApplicationInstance.BootOptions` is an interface class that exists\n      purely to document the available options; you do not need to construct it\n      manually. Simply pass a regular JavaScript object containing of the\n      desired options:\n       ```javascript\n      MyApp.visit(\"/\", { location: \"none\", rootElement: \"#container\" });\n      ```\n       ### Supported Scenarios\n       While the `BootOptions` class exposes a large number of knobs, not all\n      combinations of them are valid; certain incompatible combinations might\n      result in unexpected behavior.\n       For example, booting the instance in the full browser environment\n      while specifying a foreign `document` object (e.g. `{ isBrowser: true,\n      document: iframe.contentDocument }`) does not work correctly today,\n      largely due to Ember's jQuery dependency.\n       Currently, there are three officially supported scenarios/configurations.\n      Usages outside of these scenarios are not guaranteed to work, but please\n      feel free to file bug reports documenting your experience and any issues\n      you encountered to help expand support.\n       #### Browser Applications (Manual Boot)\n       The setup is largely similar to how Ember works out-of-the-box. Normally,\n      Ember will boot a default instance for your Application on \"DOM ready\".\n      However, you can customize this behavior by disabling `autoboot`.\n       For example, this allows you to render a miniture demo of your application\n      into a specific area on your marketing website:\n       ```javascript\n      import MyApp from 'my-app';\n       $(function() {\n        let App = MyApp.create({ autoboot: false });\n         let options = {\n          // Override the router's location adapter to prevent it from updating\n          // the URL in the address bar\n          location: 'none',\n           // Override the default `rootElement` on the app to render into a\n          // specific `div` on the page\n          rootElement: '#demo'\n        };\n         // Start the app at the special demo URL\n        App.visit('/demo', options);\n      });\n      ```\n       Or perhaps you might want to boot two instances of your app on the same\n      page for a split-screen multiplayer experience:\n       ```javascript\n      import MyApp from 'my-app';\n       $(function() {\n        let App = MyApp.create({ autoboot: false });\n         let sessionId = MyApp.generateSessionID();\n         let player1 = App.visit(`/matches/join?name=Player+1&session=${sessionId}`, { rootElement: '#left', location: 'none' });\n        let player2 = App.visit(`/matches/join?name=Player+2&session=${sessionId}`, { rootElement: '#right', location: 'none' });\n         Promise.all([player1, player2]).then(() => {\n          // Both apps have completed the initial render\n          $('#loading').fadeOut();\n        });\n      });\n      ```\n       Do note that each app instance maintains their own registry/container, so\n      they will run in complete isolation by default.\n       #### Server-Side Rendering (also known as FastBoot)\n       This setup allows you to run your Ember app in a server environment using\n      Node.js and render its content into static HTML for SEO purposes.\n       ```javascript\n      const HTMLSerializer = new SimpleDOM.HTMLSerializer(SimpleDOM.voidMap);\n       function renderURL(url) {\n        let dom = new SimpleDOM.Document();\n        let rootElement = dom.body;\n        let options = { isBrowser: false, document: dom, rootElement: rootElement };\n         return MyApp.visit(options).then(instance => {\n          try {\n            return HTMLSerializer.serialize(rootElement.firstChild);\n          } finally {\n            instance.destroy();\n          }\n        });\n      }\n      ```\n       In this scenario, because Ember does not have access to a global `document`\n      object in the Node.js environment, you must provide one explicitly. In practice,\n      in the non-browser environment, the stand-in `document` object only needs to\n      implement a limited subset of the full DOM API. The `SimpleDOM` library is known\n      to work.\n       Since there is no access to jQuery in the non-browser environment, you must also\n      specify a DOM `Element` object in the same `document` for the `rootElement` option\n      (as opposed to a selector string like `\"body\"`).\n       See the documentation on the `isBrowser`, `document` and `rootElement` properties\n      on `ApplicationInstance.BootOptions` for details.\n       #### Server-Side Resource Discovery\n       This setup allows you to run the routing layer of your Ember app in a server\n      environment using Node.js and completely disable rendering. This allows you\n      to simulate and discover the resources (i.e. AJAX requests) needed to fulfill\n      a given request and eagerly \"push\" these resources to the client.\n       ```app/initializers/network-service.js\n      import BrowserNetworkService from 'app/services/network/browser';\n      import NodeNetworkService from 'app/services/network/node';\n       // Inject a (hypothetical) service for abstracting all AJAX calls and use\n      // the appropriate implementation on the client/server. This also allows the\n      // server to log all the AJAX calls made during a particular request and use\n      // that for resource-discovery purpose.\n       export function initialize(application) {\n        if (window) { // browser\n          application.register('service:network', BrowserNetworkService);\n        } else { // node\n          application.register('service:network', NodeNetworkService);\n        }\n         application.inject('route', 'network', 'service:network');\n      };\n       export default {\n        name: 'network-service',\n        initialize: initialize\n      };\n      ```\n       ```app/routes/post.js\n      import Route from '@ember/routing/route';\n       // An example of how the (hypothetical) service is used in routes.\n       export default Route.extend({\n        model(params) {\n          return this.network.fetch(`/api/posts/${params.post_id}.json`);\n        },\n         afterModel(post) {\n          if (post.isExternalContent) {\n            return this.network.fetch(`/api/external/?url=${post.externalURL}`);\n          } else {\n            return post;\n          }\n        }\n      });\n      ```\n       ```javascript\n      // Finally, put all the pieces together\n       function discoverResourcesFor(url) {\n        return MyApp.visit(url, { isBrowser: false, shouldRender: false }).then(instance => {\n          let networkService = instance.lookup('service:network');\n          return networkService.requests;

Promises that are rejected have a rejection reason and are in the\n    rejected state.  A fulfillment value is never a thenable.\n  \n    Promises can also be said to *resolve* a value.  If this value is also a\n    promise, then the original promise's settled state will match the value's\n    settled state.  So a promise that *resolves* a promise that rejects will\n    itself reject, and a promise that *resolves* a promise that fulfills will\n    itself fulfill.\n  \n  \n    Basic Usage:\n    ------------\n  \n    ```js\n    let promise = new Promise(function(resolve, reject) {\n      // on success\n      resolve(value);\n  \n      // on failure\n      reject(reason);\n    });\n  \n    promise.then(function(value) {\n      // on fulfillment\n    }, function(reason) {\n      // on rejection\n    });\n    ```\n  \n    Advanced Usage:\n    ---------------\n  \n    Promises shine when abstracting away asynchronous interactions such as\n    `XMLHttpRequest`s.\n  \n    ```js\n    function getJSON(url) {\n      return new Promise(function(resolve, reject){\n        let xhr = new XMLHttpRequest();\n  \n        xhr.open('GET', url);\n        xhr.onreadystatechange = handler;\n        xhr.responseType = 'json';\n        xhr.setRequestHeader('Accept', 'application/json');\n        xhr.send();\n  \n        function handler() {\n          if (this.readyState === this.DONE) {\n            if (this.status === 200) {\n              resolve(this.response);\n            } else {\n              reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));\n            }\n          }\n        };\n      });\n    }\n  \n    getJSON('/posts.json').then(function(json) {\n      // on fulfillment\n    }, function(reason) {\n      // on rejection\n    });\n    ```\n  \n    Unlike callbacks, promises are great composable primitives.\n  \n    ```js\n    Promise.all([\n      getJSON('/posts'),\n      getJSON('/comments')\n    ]).then(function(values){\n      values[0] // => postsJSON\n      values[1] // => commentsJSON\n  \n      return values;\n    });\n    ```\n  \n    @class RSVP.Promise\n    @param {function} resolver\n    @param {String} label optional string for labeling the promise.\n    Useful for tooling.\n    @constructor\n  */\n  class Promise {\n    constructor(resolver, label) {\n      this._id = counter++;\n      this._label = label;\n      this._state = undefined;\n      this._result = undefined;\n      this._subscribers = [];\n\n      config.instrument && instrument('created', this);\n\n      if (noop !== resolver) {\n        typeof resolver !== 'function' && needsResolver();\n        this instanceof Promise ?

This is called *assimilation*.\n  \n    ```js\n    findUser().then(function (user) {\n      return findCommentsByAuthor(user);\n    }).then(function (comments) {\n      // The user's comments are now available\n    });\n    ```\n  \n    If the assimliated promise rejects, then the downstream promise will also reject.\n  \n    ```js\n    findUser().then(function (user) {\n      return findCommentsByAuthor(user);\n    }).then(function (comments) {\n      // If `findCommentsByAuthor` fulfills, we'll have the value here\n    }, function (reason) {\n      // If `findCommentsByAuthor` rejects, we'll have the reason here\n    });\n    ```\n  \n    Simple Example\n    --------------\n  \n    Synchronous Example\n  \n    ```javascript\n    let result;\n  \n    try {\n      result = findResult();\n      // success\n    } catch(reason) {\n      // failure\n    }\n    ```\n  \n    Errback Example\n  \n    ```js\n    findResult(function(result, err){\n      if (err) {\n        // failure\n      } else {\n        // success\n      }\n    });\n    ```\n  \n    Promise Example;\n  \n    ```javascript\n    findResult().then(function(result){\n      // success\n    }, function(reason){\n      // failure\n    });\n    ```\n  \n    Advanced Example\n    --------------\n  \n    Synchronous Example\n  \n    ```javascript\n    let author, books;\n  \n    try {\n      author = findAuthor();\n      books  = findBooksByAuthor(author);\n      // success\n    } catch(reason) {\n      // failure\n    }\n    ```\n  \n    Errback Example\n  \n    ```js\n  \n    function foundBooks(books) {\n  \n    }\n  \n    function failure(reason) {\n  \n    }\n  \n    findAuthor(function(author, err){\n      if (err) {\n        failure(err);\n        // failure\n      } else {\n        try {\n          findBoooksByAuthor(author, function(books, err) {\n            if (err) {\n              failure(err);\n            } else {\n              try {\n                foundBooks(books);\n              } catch(reason) {\n                failure(reason);\n              }\n            }\n          });\n        } catch(error) {\n          failure(err);\n        }\n        // success\n      }\n    });\n    ```\n  \n    Promise Example;\n  \n    ```javascript\n    findAuthor().\n      then(findBooksByAuthor).\n      then(function(books){\n        // found books\n    }).catch(function(reason){\n      // something went wrong\n    });\n    ```\n  \n    @method then\n    @param {Function} onFulfillment\n    @param {Function} onRejection\n    @param {String} label optional string for labeling the promise.\n    Useful for tooling.\n    @return {Promise}\n  */\n  Promise.prototype.then = then;\n\n  function makeObject(_, argumentNames) {\n    let obj = {};\n    let length = _.length;\n    let args = new Array(length);\n\n    for (let x = 0; x < length; x++) {\n      args[x] = _[x];\n    }\n\n    for (let i = 0; i < argumentNames.length; i++) {\n      let name = argumentNames[i];\n      obj[name] = args[i + 1];\n    }\n\n    return obj;\n  }\n\n  function arrayResult(_) {\n    let length = _.length;\n    let args = new Array(length - 1);\n\n    for (let i = 1; i < length; i++) {\n      args[i - 1] = _[i];\n    }\n\n    return args;\n  }\n\n  function wrapThenable(then, promise) {\n    return {\n      then(onFulFillment, onRejection) {\n        return then.call(promise, onFulFillment, onRejection);\n      }\n    };\n  }\n\n  /**\n    `RSVP.denodeify` takes a 'node-style' function and returns a function that\n    will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the\n    browser when you'd prefer to use promises over using callbacks. For example,\n    `denodeify` transforms the following:\n  \n    ```javascript\n    let fs = require('fs');\n  \n    fs.readFile('myfile.txt', function(err, data){\n      if (err) return handleError(err);\n      handleData(data);\n    });\n    ```\n  \n    into:\n  \n    ```javascript\n    let fs = require('fs');\n    let readFile = RSVP.denodeify(fs.readFile);\n  \n    readFile('myfile.txt').then(handleData, handleError);\n    ```\n  \n    If the node function has multiple success parameters, then `denodeify`\n    just returns the first one:\n  \n    ```javascript\n    let request = RSVP.denodeify(require('request'));\n  \n    request('http://example.com').then(function(res) {\n      // ...\n    });\n    ```\n  \n    However, if you need all success parameters, setting `denodeify`'s\n    second parameter to `true` causes it to return all success parameters\n    as an array:\n  \n    ```javascript\n    let request = RSVP.denodeify(require('request'), true);\n  \n    request('http://example.com').then(function(result) {\n      // result[0] -> res\n      // result[1] -> body\n    });\n    ```\n  \n    Or if you pass it an array with names it returns the parameters as a hash:\n  \n    ```javascript\n    let request = RSVP.denodeify(require('request'), ['res', 'body']);\n  \n    request('http://example.com').then(function(result) {\n      // result.res\n      // result.body\n    });\n    ```\n  \n    Sometimes you need to retain the `this`:\n  \n    ```javascript\n    let app = require('express')();\n    let render = RSVP.denodeify(app.render.bind(app));\n    ```\n  \n    The denodified function inherits from the original function. It works in all\n    environments, except IE 10 and below. Consequently all properties of the original\n    function are available to you. However, any properties you change on the\n    denodeified function won't be changed on the original function. Example:\n  \n    ```javascript\n    let request = RSVP.denodeify(require('request')),\n        cookieJar = request.jar(); // <- Inheritance is used here\n  \n    request('http://example.com', {jar: cookieJar}).then(function(res) {\n      // cookieJar.cookies holds now the cookies returned by example.com\n    });\n    ```\n  \n    Using `denodeify` makes it easier to compose asynchronous operations instead\n    of using callbacks. For example, instead of:\n  \n    ```javascript\n    let fs = require('fs');\n  \n    fs.readFile('myfile.txt', function(err, data){\n      if (err) { ... } // Handle error\n      fs.writeFile('myfile2.txt', data, function(err){\n        if (err) { ... } // Handle error\n        console.log('done')\n      });\n    });\n    ```\n  \n    you can chain the operations together using `then` from the returned promise:\n  \n    ```javascript\n    let fs = require('fs');\n    let readFile = RSVP.denodeify(fs.readFile);\n    let writeFile = RSVP.denodeify(fs.writeFile);\n  \n    readFile('myfile.txt').then(function(data){\n      return writeFile('myfile2.txt', data);\n    }).then(function(){\n      console.log('done')\n    }).catch(function(error){\n      // Handle error\n    });\n    ```\n  \n    @method denodeify\n    @static\n    @for RSVP\n    @param {Function} nodeFunc a 'node-style' function that takes a callback as\n    its last argument.
