`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 = resolve(1);
|
||
let promise2 = resolve(2);
|
||
let promise3 = resolve(3);
|
||
let promises = [ promise1, promise2, promise3 ];
|
||
|
||
Promise.all(promises).then(function(array){
|
||
// The array here would be [ 1, 2, 3 ];
|
||
});
|
||
```
|
||
|
||
If any of the `promises` given to `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 = resolve(1);
|
||
let promise2 = reject(new Error("2"));
|
||
let promise3 = reject(new Error("3"));
|
||
let promises = [ promise1, promise2, promise3 ];
|
||
|
||
Promise.all(promises).then(function(array){
|
||
// Code here never runs because there are rejected promises!
|
||
}, function(error) {
|
||
// error.message === "2"
|
||
});

```

`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 Promise(function(resolve, reject){
|

setTimeout(function(){

resolve('promise 1');

});
|
||
|
||
Promise.race([promise1, promise2]).then(function(result){
|
||
// result === 'promise 2' because it was resolved before promise1
|
||
// was resolved.
|
||
});
|
||
```
|
||
|
||
`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 Promise(function(resolve, reject){
|
||
setTimeout(function(){
|
||
resolve('promise 1');
|
||
}, 200);
|
||
});
|
||
|
||
let promise2 = new Promise(function(resolve, reject){
|
||
setTimeout(function(){
|
||
reject(new Error('promise 2'));
|
||
}, 100);
|
||
});
|
||
|
||
Promise.race([promise1, promise2]).then(function(result){

// reason.message === 'promise 2' because promise 2 became rejected before
|
||
// promise 1 became fulfilled
|
||
});
|
||
```
|
||
|
||
An example real-world use case is implementing timeouts:
|
||
|
||
```javascript
|
||
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;
|
||
});
|
||
```
|
||
|
||
@class Promise
|
||
@param {Function} resolver

||
Useful for tooling.
|
||
@constructor

||
*/
|
||
|
||
var Promise$2 = function () {
|
||
function Promise(resolver) {
|
||
classCallCheck(this, Promise);
|
||
|
||
this[PROMISE_ID] = nextId();
|
||
this._result = this._state = undefined;
|
||
this._subscribers = [];
|
||
|
||
if (noop !== resolver) {
|
||
typeof resolver !== 'function' && needsResolver();
|
||
this instanceof Promise ? initializePromise(this, resolver) : needsNew();
|
||
}
|
||
}
|
||
|
||
/**
|
||
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
|
||
});
|
||
```
