`RSVP.defer` returns an object similar to jQuery's `$.Deferred` objects.
`RSVP.defer` should be used when porting over code reliant on `$.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
var deferred = RSVP.defer();
deferred.resolve("Success!");
defered.promise.then(function(value){
// value here is "Success!"
});
```
@method defer
@for RSVP
@param {String} -

`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.filterFn` 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 filterFn = function(item){
return item > 1;
};
RSVP.filter(promises, filterFn).then(function(result){
// 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 promises'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){
return item > 1;
};
RSVP.filter(promises, filterFn).then(function(array){
// 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){
return RSVP.resolve(user);
});
var 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;
});
```

`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 as the first argument, or as the reason to
the rejection handler. For 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.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);
```
Using `denodeify` makes it easier to compose asynchronous operations instead
of using callbacks. For example, instead of:
```javascript
var fs = require('fs');
var log = require('some-async-logger');
fs.readFile('myfile.txt', function(err, data){
if (err) return handleError(err);
fs.writeFile('myfile2.txt', data, function(err){
if (err) throw err;
log('success', function(err) {
if (err) throw err;
});
});
});
```
You can chain the operations together using `then` from the returned promise:
```javascript
var fs = require('fs');
var denodeify = RSVP.denodeify;
var readFile = denodeify(fs.readFile);
var writeFile = denodeify(fs.writeFile);
var log = denodeify(require('some-async-logger'));
readFile('myfile.txt').then(function(data){
return writeFile('myfile2.txt', data);
}).then(function(){
return log('SUCCESS');
}).then(function(){
// success handler
}, function(reason){
// rejection handler
});
```

@for RSVP

@param {Any} binding optional argument for binding the "this" value when
calling the `nodeFunc` function.

Returns a promise that is fulfilled when all the given promises have been
fulfilled, or rejected if any of them become rejected. The return promise
is fulfilled with an array that gives all the values in the order they were
passed in the `promises` array argument.
Example:
```javascript
var promise1 = RSVP.resolve(1);

var promises = [ promise1, promise2, promise3 ];
RSVP.Promise.all(promises).then(function(array){

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

`RSVP.Promise.cast` returns the same promise if that promise shares a constructor
with the promise being casted.
Example:
```javascript
var promise = RSVP.resolve(1);
var casted = RSVP.Promise.cast(promise);
console.log(promise === casted); // true
```
In the case of a promise whose constructor does not match, it is assimilated.
The resulting promise will fulfill or reject based on the outcome of the
promise being casted.
In the case of a non-promise, a promise which will fulfill with that value is
returned.
Example:
```javascript
var value = 1; // could be a number, boolean, string, undefined...
var casted = RSVP.Promise.cast(value);
console.log(value === casted); // false
console.log(casted instanceof RSVP.Promise) // true
casted.then(function(val) {
val === value // => true
});
```
`RSVP.Promise.cast` is similar to `RSVP.resolve`, but `RSVP.Promise.cast` differs in the
following ways:
* `RSVP.Promise.cast` serves as a memory-efficient way of getting a promise, when you
have something that could either be a promise or a value. RSVP.resolve
will have the same effect but will create a new promise wrapper if the
argument is a promise.
* `RSVP.Promise.cast` is a way of casting incoming thenables or promise subclasses to
promises of the exact class specified, so that the resulting object's `then` is
ensured to have the behavior of the constructor you are calling cast on (i.e., RSVP.Promise).

`RSVP.Promise.race` allows you to watch a series of promises and act as soon as the
first promise given to the `promises` argument fulfills or rejects.
Example:
```javascript
var promise1 = new RSVP.Promise(function(resolve, reject){
setTimeout(function(){
resolve("promise 1");
}, 200);
});
var promise2 = new RSVP.Promise(function(resolve, reject){

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

`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 throw the error
again so the error can be handled by the promise.
```javascript
function throws(){
throw new Error('Whoops!');
}
var promise = new RSVP.Promise(function(resolve, reject){
throws();
});
promise.fail(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 `.fail` on the returned promise.
