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

/**
|

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
|
||||
});
|
||||
```
|
||||
|
||||
