* Injecting one fullName on a type
Example:
```javascript

registry.register('store:main', Store);
registry.register('store:secondary', OtherStore);
registry.register('model:user', User);
registry.register('model:post', Post);

registry.factoryInjection('model', 'store', 'store:main');
// injecting one fullName on another fullName
registry.factoryInjection('model:post', 'secondaryStore', 'store:secondary');
var UserFactory = container.lookupFactory('model:user');
var PostFactory = container.lookupFactory('model:post');
var store = container.lookup('store:main');

UserFactory.secondaryStore instanceof OtherStore; //=> false
PostFactory.store instanceof Store; //=> true

```
And associate it by name using a view's `templateName` property:
```javascript
AView = Ember.View.extend({
templateName: 'some-template'
});
```
If you have nested routes, your Handlebars template will look like this:
```html
```
And `templateName` property:
```javascript
AView = Ember.View.extend({
templateName: 'posts/new'
});
```
Using a value for `templateName` that does not have a template
with a matching `data-template-name` attribute will throw an error.
For views classes that may have a template later defined (e.g. as the block
portion of a `{{view}}` helper call in another template or in
a subclass), you can provide a `defaultTemplate` property set to compiled
template function. If a template is not later provided for the view instance
the `defaultTemplate` value will be used:
```javascript
AView = Ember.View.extend({
defaultTemplate: Ember.HTMLBars.compile('I was the default'),
template: null,
templateName: null
});
```
Will result in instances with an HTML representation of:
```html
I was the default
```
If a `template` or `templateName` is provided it will take precedence over
`defaultTemplate`:
```javascript
AView = Ember.View.extend({
defaultTemplate: Ember.HTMLBars.compile('I was the default')
});
aView = AView.create({
template: Ember.HTMLBars.compile('I was the template, not default')
});
```
Will result in the following HTML representation when rendered:
```html
I was the template, not default
```
## View Context
The default context of the compiled template is the view's controller:
```javascript
AView = Ember.View.extend({
template: Ember.HTMLBars.compile('Hello {{excitedGreeting}}')
});
aController = Ember.Object.create({
firstName: 'Barry',
excitedGreeting: Ember.computed('content.firstName', function() {
return this.get('content.firstName') + '!!!';
})
});
aView = AView.create({
controller: aController
});
```
Will result in an HTML representation of:
```html
Hello Barry!!!
```
A context can also be explicitly supplied through the view's `context`
property. If the view has neither `context` nor `controller` properties, the
`parentView`'s context will be used.
## Layouts
Views can have a secondary template that wraps their main template. Like
primary templates, layouts can be any function that accepts an optional
context parameter and returns a string of HTML that will be inserted inside
view's tag. Views whose HTML element is self closing (e.g. ``)
cannot have a layout and this property will be ignored.
Most typically in Ember a layout will be a compiled template.
A view's layout can be set directly with the `layout` property or reference
an existing template by name with the `layoutName` property.
A template used as a layout must contain a single use of the
`{{yield}}` helper. The HTML contents of a view's rendered `template` will be
inserted at this location:
```javascript
AViewWithLayout = Ember.View.extend({
layout: Ember.HTMLBars.compile("
{{yield}}
"),
template: Ember.HTMLBars.compile("I got wrapped")
});
```
Will result in view instances with an HTML representation of:
```html
I got wrapped
```
See [Ember.Templates.helpers.yield](/api/classes/Ember.Templates.helpers.html#method_yield)
for more information.
## Responding to Browser Events
Views can respond to user-initiated events in one of three ways: method
implementation, through an event manager, and through `{{action}}` helper use
in their template or layout.
### Method Implementation
Views can respond to user-initiated events by implementing a method that
matches the event name. A `jQuery.Event` object will be passed as the
argument to this method.
```javascript
AView = Ember.View.extend({
click: function(event) {
// will be called when an instance's
// rendered element is clicked
}
});
```
### Event Managers
Views can define an object as their `eventManager` property. This object can
then implement methods that match the desired event names. Matching events
that occur on the view's rendered HTML or the rendered HTML of any of its DOM
descendants will trigger this method. A `jQuery.Event` object will be passed
as the first argument to the method and an `Ember.View` object as the
second. The `Ember.View` will be the view whose rendered HTML was interacted
with. This may be the view with the `eventManager` property or one of its
descendant views.
```javascript
AView = Ember.View.extend({
eventManager: Ember.Object.create({
doubleClick: function(event, view) {
// will be called when an instance's
// rendered element or any rendering
// of this view's descendant
// elements is clicked
}
})
});
```
An event defined for an event manager takes precedence over events of the
same name handled through methods on the view.
```javascript
AView = Ember.View.extend({
mouseEnter: function(event) {
// will never trigger.
},
eventManager: Ember.Object.create({
mouseEnter: function(event, view) {
// takes precedence over AView#mouseEnter
}
})
});
```
Similarly a view's event manager will take precedence for events of any views
rendered as a descendant. A method name that matches an event name will not
be called if the view instance was rendered inside the HTML representation of
a view that has an `eventManager` property defined that handles events of the
name. Events not handled by the event manager will still trigger method calls
on the descendant.
```javascript
var App = Ember.Application.create();
App.OuterView = Ember.View.extend({
template: Ember.HTMLBars.compile("outer {{#view 'inner'}}inner{{/view}} outer"),
eventManager: Ember.Object.create({
mouseEnter: function(event, view) {
// view might be instance of either
// OuterView or InnerView depending on
// where on the page the user interaction occurred
}
})
});
App.InnerView = Ember.View.extend({
click: function(event) {
// will be called if rendered inside
// an OuterView because OuterView's
// eventManager doesn't handle click events
},
mouseEnter: function(event) {
// will never be called if rendered inside
// an OuterView.
}
});
```
### `{{action}}` Helper
See [Ember.Templates.helpers.action](/api/classes/Ember.Templates.helpers.html#method_action).
### Event Names
All of the event handling approaches described above respond to the same set
of events. The names of the built-in events are listed below. (The hash of
built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
can be registered by using `Ember.Application.customEvents`.
Touch events:
* `touchStart`
* `touchMove`
* `touchEnd`
* `touchCancel`
Keyboard events
* `keyDown`
* `keyUp`
* `keyPress`
Mouse events
* `mouseDown`
* `mouseUp`
* `contextMenu`
* `click`
* `doubleClick`
* `mouseMove`
* `focusIn`
* `focusOut`
* `mouseEnter`
* `mouseLeave`
Form events:
* `submit`
* `change`
* `focusIn`
* `focusOut`
* `input`
HTML5 drag and drop events:
* `dragStart`
* `drag`
* `dragEnter`
* `dragLeave`
* `dragOver`
* `dragEnd`
* `drop`
## `{{view}}` Helper
Other `Ember.View` instances can be included as part of a view's template by
using the `{{view}}` helper. See [Ember.Templates.helpers.view](/api/classes/Ember.Templates.helpers.html#method_view)
for additional information.

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

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

a fail-fast method, it waits until all the promises have returned and
shows you all the results. This is useful if you want to handle multiple
promises' failure states together as a set.
Returns a promise that is fulfilled when all the given promises have been
settled. The return promise is fulfilled with an array of the states of
the promises passed into the `promises` array argument.
Each state object will either indicate fulfillment or rejection, and
provide the corresponding value or reason. The states will take one of
the following formats:
```javascript
{ state: 'fulfilled', value: value }
or
{ state: 'rejected', reason: reason }
```
Example:
```javascript
var promise1 = RSVP.Promise.resolve(1);
var promise2 = RSVP.Promise.reject(new Error('2'));
var promise3 = RSVP.Promise.reject(new Error('3'));
var promises = [ promise1, promise2, promise3 ];

// array == [
// { state: 'fulfilled', value: 1 },
// { state: 'rejected', reason: Error },
// { state: 'rejected', reason: Error }
// ]
// Note that for the second item, reason.message will be '2', and for the
// third item, reason.message will be '3'.
}, function(error) {
// Not run. (This block would only be called if allSettled had failed,
// for instance if passed an incorrect argument type.)

/**
`RSVP.filter` is similar to JavaScript's native `filter` method, except that it
waits for all promises to become fulfilled before running the `filterFn` on
each item in given to `promises`. `RSVP.filter` returns a promise that will
become fulfilled with the result of running `filterFn` on the values the
promises become fulfilled with.
For example:
```javascript
var promise1 = RSVP.resolve(1);
var promise2 = RSVP.resolve(2);
var promise3 = RSVP.resolve(3);
var promises = [promise1, promise2, promise3];
var filterFn = function(item){

// result is [ 2, 3 ]

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

};

// Code here never runs because there are rejected promises!
}, function(reason) {
// reason.message === '2'
});
```
`RSVP.filter` will also wait for any promises returned from `filterFn`.
For instance, you may want to fetch a list of users then return a subset
of those users based on some asynchronous operation:
```javascript
var alice = { name: 'alice' };
var bob = { name: 'bob' };
var users = [ alice, bob ];
var promises = users.map(function(user){

};

// true, because the server told us only Alice can create a blog post.
users.length === 1;
// false, because Alice is the only user present in `users`
users[0] === bob;

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

/**
`RSVP.hash` is similar to `RSVP.all`, but takes an object instead of an array
for its `promises` argument.
Returns a promise that is fulfilled when all the given promises have been
fulfilled, or rejected if any of them become rejected. The returned promise
is fulfilled with a hash that has the same key names as the `promises` object
argument. If any of the values in the object are not promises, they will
simply be copied over to the fulfilled object.
Example:
```javascript
var promises = {
myPromise: RSVP.resolve(1),
yourPromise: RSVP.resolve(2),
theirPromise: RSVP.resolve(3),
notAPromise: 4
};
RSVP.hash(promises).then(function(hash){
// hash here is an object that looks like:
// {
// myPromise: 1,
// yourPromise: 2,
// theirPromise: 3,
// notAPromise: 4
// }
});
````
If any of the `promises` given to `RSVP.hash` are rejected, the first promise
that is rejected will be given as the reason to the rejection handler.
Example:
```javascript
var promises = {
myPromise: RSVP.resolve(1),
rejectedPromise: RSVP.reject(new Error('rejectedPromise')),
anotherRejectedPromise: RSVP.reject(new Error('anotherRejectedPromise')),
};
RSVP.hash(promises).then(function(hash){
// Code here never runs because there are rejected promises!
}, function(reason) {
// reason.message === 'rejectedPromise'
});
```
An important note: `RSVP.hash` is intended for plain JavaScript objects that
are just a set of keys and values. `RSVP.hash` will NOT preserve prototype
chains.
Example:
```javascript
function MyConstructor(){
this.example = RSVP.resolve('Example');
}
MyConstructor.prototype = {
protoProperty: RSVP.resolve('Proto Property')
};
var myObject = new MyConstructor();
RSVP.hash(myObject).then(function(hash){
// protoProperty will not be present, instead you will just have an
// object that looks like:
// {
// example: 'Example'
// }
//
// hash.hasOwnProperty('protoProperty'); // false
// 'undefined' === typeof hash.protoProperty
});

/**
`RSVP.map` is similar to JavaScript's native `map` method, except that it
waits for all promises to become fulfilled before running the `mapFn` on
each item in given to `promises`. `RSVP.map` returns a promise that will
become fulfilled with the result of running `mapFn` on the values the promises
become fulfilled with.
For example:
```javascript
var promise1 = RSVP.resolve(1);
var promise2 = RSVP.resolve(2);
var promise3 = RSVP.resolve(3);
var promises = [ promise1, promise2, promise3 ];
var mapFn = function(item){
return item + 1;
};
RSVP.map(promises, mapFn).then(function(result){
// result is [ 2, 3, 4 ]
});
```
If any of the `promises` given to `RSVP.map` are rejected, the first promise
that is rejected will be given as an argument to the returned promise's
rejection handler. For example:
```javascript
var promise1 = RSVP.resolve(1);
var promise2 = RSVP.reject(new Error('2'));
var promise3 = RSVP.reject(new Error('3'));
var promises = [ promise1, promise2, promise3 ];
var mapFn = function(item){
return item + 1;
};
RSVP.map(promises, mapFn).then(function(array){
// Code here never runs because there are rejected promises!
}, function(reason) {
// reason.message === '2'
});
```
`RSVP.map` will also wait if a promise is returned from `mapFn`. For example,
say you want to get all comments from a set of blog posts, but you need
the blog posts first because they contain a url to those comments.
```javscript
var mapFn = function(blogPost){
// getComments does some ajax and returns an RSVP.Promise that is fulfilled
// with some comments data
return getComments(blogPost.comments_url);
};
// getBlogPosts does some ajax and returns an RSVP.Promise that is fulfilled
// with some blog post data
RSVP.map(getBlogPosts(), mapFn).then(function(comments){
// comments is the result of asking the server for the comments
// of all blog posts returned from getBlogPosts()

/**
`RSVP.denodeify` takes a 'node-style' function and returns a function that
will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
browser when you'd prefer to use promises over using callbacks. For example,
`denodeify` transforms the following:
```javascript
var fs = require('fs');
fs.readFile('myfile.txt', function(err, data){
if (err) return handleError(err);
handleData(data);
});
```
into:
```javascript
var fs = require('fs');
var readFile = RSVP.denodeify(fs.readFile);
readFile('myfile.txt').then(handleData, handleError);
```
If the node function has multiple success parameters, then `denodeify`
just returns the first one:
```javascript
var request = RSVP.denodeify(require('request'));
request('http://example.com').then(function(res) {
// ...
});
```
However, if you need all success parameters, setting `denodeify`'s
second parameter to `true` causes it to return all success parameters
as an array:
```javascript
var request = RSVP.denodeify(require('request'), true);
request('http://example.com').then(function(result) {
// result[0] -> res
// result[1] -> body
});
```
Or if you pass it an array with names it returns the parameters as a hash:
```javascript
var request = RSVP.denodeify(require('request'), ['res', 'body']);
request('http://example.com').then(function(result) {
// result.res
// result.body
});
```
Sometimes you need to retain the `this`:
```javascript
var app = require('express')();
var render = RSVP.denodeify(app.render.bind(app));
```
The denodified function inherits from the original function. It works in all
environments, except IE 10 and below. Consequently all properties of the original
function are available to you. However, any properties you change on the
denodeified function won't be changed on the original function. Example:
```javascript
var request = RSVP.denodeify(require('request')),
cookieJar = request.jar(); // <- Inheritance is used here
request('http://example.com', {jar: cookieJar}).then(function(res) {
// cookieJar.cookies holds now the cookies returned by example.com
});
```
Using `denodeify` makes it easier to compose asynchronous operations instead
of using callbacks. For example, instead of:
```javascript
var fs = require('fs');
fs.readFile('myfile.txt', function(err, data){
if (err) { ... } // Handle error
fs.writeFile('myfile2.txt', data, function(err){
if (err) { ... } // Handle error
console.log('done')
});
});
```
you can chain the operations together using `then` from the returned promise:
```javascript
var fs = require('fs');
var readFile = RSVP.denodeify(fs.readFile);
var writeFile = RSVP.denodeify(fs.writeFile);
readFile('myfile.txt').then(function(data){
return writeFile('myfile2.txt', data);
}).then(function(){
console.log('done')
}).catch(function(error){
// Handle error
});
```

```
`RSVP.Promise.race` is deterministic in that only the state of the first
settled promise matters. For example, even if other promises given to the
`promises` array argument are resolved, but the first settled promise has
become rejected before the other promises became fulfilled, the returned
promise will become rejected:
```javascript
var promise1 = new RSVP.Promise(function(resolve, reject){

});
var promise2 = new RSVP.Promise(function(resolve, reject){

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

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

`RSVP.rethrow` will rethrow an error on the next turn of the JavaScript event
loop in order to aid debugging.
Promises A+ specifies that any exceptions that occur with a promise must be
caught by the promises implementation and bubbled to the last handler. For
this reason, it is recommended that you always specify a second rejection
handler function to `then`. However, `RSVP.rethrow` will throw the exception
outside of the promise, so it bubbles up to your console if in the browser,
or domain/cause uncaught exception in Node. `rethrow` will also throw the
error again so the error can be handled by the promise per the spec.
```javascript
function throws(){
throw new Error('Whoops!');
}
var promise = new RSVP.Promise(function(resolve, reject){
throws();
});
promise.catch(RSVP.rethrow).then(function(){
// Code here doesn't run because the promise became rejected due to an
// error!
}, function (err){
// handle the error here
});
```
The 'Whoops' error will be thrown on the next turn of the event loop
and you can watch for it in your console. You can also handle it using a
rejection handler given to `.then` or `.catch` on the returned promise.
@method rethrow
