/**
|
||||
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;
|
||||
});
|
||||
```
|
||||
|
||||
@class Promise
|
||||
@param {function} resolver

||||

|
||||

||||

|
||||
function Promise(resolver) {
|
||||
this._id = counter++;
|
||||
this._state = undefined;
|
||||
this._result = undefined;
|
||||
this._subscribers = [];
|
||||
|
||||
if (noop !== resolver) {
|
||||
if (!isFunction(resolver)) {
|
||||
needsResolver();
|
||||
}
|
||||
|
||||
if (!(this instanceof Promise)) {
|
||||
needsNew();
|
||||
}
|
||||
|
||||
initializePromise(this, resolver);
|
||||
}
|
||||
}
|
||||
|
||||
Promise.all = all;
|
||||
Promise.race = race;
|
||||
Promise.resolve = Resolve;
|
||||
Promise.reject = Reject;
|
||||
Promise._setScheduler = setScheduler;
|
||||
Promise._setAsap = setAsap;

|

/**
|
||||
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
|
||||
});
|
||||
```
|
||||
|
||||

`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.

`Promise.race` is deterministic in that only the state of the first

`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 Promise(function(resolve, reject){

var promise2 = new Promise(function(resolve, reject){
