|
|
|
+ `Promise.resolve` returns a promise that will become resolved with the
|
|
|
+ passed `value`. It is shorthand for the following:
|
|
|
+
|
|
|
+ ```javascript
|
|
|
+ let promise = new Promise(function(resolve, reject){
|
|
|
+ resolve(1);
|
|
|
+ });
|
|
|
+
|
|
|
+ promise.then(function(value){
|
|
|
+ // value === 1
|
|
|
+ });
|
|
|
+ ```
|
|
|
+
|
|
|
+ Instead of writing the above, your code now simply becomes the following:
|
|
|
+
|
|
|
+ ```javascript
|
|
|
+ let promise = Promise.resolve(1);
|
|
|
+
|
|
|
+ promise.then(function(value){
|
|
|
+ // value === 1
|
|
|
+ });
|
|
|
+ ```

|
+ @method resolve
|

|

|
|

|
|
|
+ `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);
|

|
|
|
+ `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');
|
|
|
+ }, 200);
|
|
|
+ });
|
|
|
+
|
|
|
+ let promise2 = new Promise(function(resolve, reject){
|
|
|
+ setTimeout(function(){
|
|
|
+ resolve('promise 2');
|
|
|
+ }, 100);
|
|
|
+ });
|
|
|
+
|
|
|
+ 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){
|
|
|
+ // Code here never runs
|
|
|
+ }, function(reason){
|
|
|
+ // reason.message === 'promise 2' because promise 2 became rejected before
|
|
|
+ // promise 1 became fulfilled
|
|
|
+ });
|
|
|
+ ```
|
|

+

+/**
|
|
|
+ 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) {
|
|
|
+ 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
|

|
|
+ }, 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
|
|
|
+ });
|
|
|
+ ```
