/**
`RSVP.Promise.all` accepts an array of promises, and returns a new promise which
is fulfilled with an array of fulfillment values for the passed promises, or
rejected with the reason of the first passed promise to be rejected. It casts all
elements of the passed iterable to promises as it runs this algorithm.
Example:
```javascript
let promise1 = RSVP.resolve(1);
let promise2 = RSVP.resolve(2);
let promise3 = RSVP.resolve(3);
let promises = [ promise1, promise2, promise3 ];
RSVP.Promise.all(promises).then(function(array){
// The array here would be [ 1, 2, 3 ];
});
```
If any of the `promises` given to `RSVP.all` are rejected, the first promise
that is rejected will be given as an argument to the returned promises's
rejection handler. For example:
Example:
```javascript
let promise1 = RSVP.resolve(1);
let promise2 = RSVP.reject(new Error("2"));
let promise3 = RSVP.reject(new Error("3"));
let promises = [ promise1, promise2, promise3 ];
RSVP.Promise.all(promises).then(function(array){
// Code here never runs because there are rejected promises!
}, function(error) {
// error.message === "2"
});
```
@method all
@static
@param {Array} entries array of promises
@param {String} label optional string for labeling the promise.

@return {Promise} promise that is fulfilled when all `promises` have been
fulfilled, or rejected if any of them become rejected.
@static
*/
function all(entries, label) {
if (!Array.isArray(entries)) {
return this.reject(new TypeError("Promise.all must be called with an array"), label);
}

}
/**
`RSVP.Promise.race` returns a new promise which is settled in the same way as the
first passed promise to settle.
Example:
```javascript
let promise1 = new RSVP.Promise(function(resolve, reject){
setTimeout(function(){
resolve('promise 1');
}, 200);
});
let promise2 = new RSVP.Promise(function(resolve, reject){
setTimeout(function(){
resolve('promise 2');
}, 100);
});
RSVP.Promise.race([promise1, promise2]).then(function(result){
// result === 'promise 2' because it was resolved before promise1
// was resolved.
});
```
`RSVP.Promise.race` is deterministic in that only the state of the first
settled promise matters. For example, even if other promises given to the
`promises` array argument are resolved, but the first settled promise has
become rejected before the other promises became fulfilled, the returned
promise will become rejected:
```javascript
let promise1 = new RSVP.Promise(function(resolve, reject){
setTimeout(function(){
resolve('promise 1');
}, 200);
});
let promise2 = new RSVP.Promise(function(resolve, reject){
setTimeout(function(){
reject(new Error('promise 2'));
}, 100);
});
RSVP.Promise.race([promise1, promise2]).then(function(result){
// Code here never runs
}, function(reason){
// reason.message === 'promise 2' because promise 2 became rejected before
// promise 1 became fulfilled
});
```

```javascript
RSVP.Promise.race([ajax('foo.json'), timeout(5000)])
```

/**
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
let 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){
let 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;
});
```

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
let 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
let 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

/**
`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
let fs = require('fs');
fs.readFile('myfile.txt', function(err, data){
if (err) return handleError(err);
handleData(data);
});
```
into:
```javascript
let fs = require('fs');
let 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
let 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
let 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
let 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
let app = require('express')();
let 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
let 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
let 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
let fs = require('fs');
let readFile = RSVP.denodeify(fs.readFile);
let 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.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
let 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
let 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(){

/**
`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
let 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
let 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')
};
let myObject = new MyConstructor();
RSVP.hashSettled(myObject).then(function(hash){
// protoProperty will not be present, instead you will just have an
// object that looks like:
// {
// example: { state: 'fulfilled', value: 'Example' }
// }
//
// hash.hasOwnProperty('protoProperty'); // false
// 'undefined' === typeof hash.protoProperty
});

/**
`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!');
}
let 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.

`RSVP.defer` returns an object similar to jQuery's `$.Deferred`.
`RSVP.defer` should be used when porting over code reliant on `$.Deferred`'s
interface. New code should use the `RSVP.Promise` constructor instead.
The object returned from `RSVP.defer` is a plain object with three properties:
* promise - an `RSVP.Promise`.
* reject - a function that causes the `promise` property on this object to
become rejected
* resolve - a function that causes the `promise` property on this object to
become fulfilled.
Example:
```javascript
let deferred = RSVP.defer();
deferred.resolve("Success!");
deferred.promise.then(function(value){
// value here is "Success!"
});

/**
`RSVP.map` is similar to JavaScript's native `map` method. `mapFn` is eagerly called
meaning that as soon as any promise resolves its value will be passed to `mapFn`.
`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
let promise1 = RSVP.resolve(1);
let promise2 = RSVP.resolve(2);
let promise3 = RSVP.resolve(3);
let promises = [ promise1, promise2, promise3 ];
let 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
let promise1 = RSVP.resolve(1);
let promise2 = RSVP.reject(new Error('2'));
let promise3 = RSVP.reject(new Error('3'));
let promises = [ promise1, promise2, promise3 ];
let 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
let 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()
});
```

`filterFn` is eagerly called meaning that as soon as any promise

of those users based on some asynchronous operation:
```javascript
let alice = { name: 'alice' };
let bob = { name: 'bob' };
let users = [ alice, bob ];
let promises = users.map(function(user){

});
let filterFn = function(user){
// Here, Alice has permissions to create a blog post, but Bob does not.
return getPrivilegesForUser(user).then(function(privs){
return privs.can_create_blog_post === true;
});
};
RSVP.filter(promises, filterFn).then(function(users){
// 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;
