- ```
-
- 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 ];

- }, function(reason) {

- });
- ```
-
- `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 users = [ alice, bob ];
-
- var promises = users.map(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.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 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 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 becuase 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);
- ```
-
- 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 {Function} nodeFunc a "node-style" function that takes a callback as
- its last argument. The callback expects an error to be passed as its first

- @param {Any} binding optional argument for binding the "this" value when

- /**
-
- 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.
-
-
- 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;
- });
- ```

-
- A promise represents 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.
-
- ```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 "Found user, but still unhappy";
- }, function (reason) {
- throw "`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
- });
- ```

- result = findResult();

- 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.Promise.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).
-
- @method cast
- @for RSVP.Promise
- @param {Object} object to be casted
- @param {String} label optional string for labeling the promise.
- Useful for tooling.
- @return {Promise} promise

-
- `RSVP.Promise.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:
-

- handler function to `then`. However, `RSVP.rethrow` will throw the exception
