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 */ 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(); } } Promise.all = all; Promise.race = race; Promise.resolve = resolve; Promise.reject = reject; Promise._setScheduler = setScheduler; Promise._setAsap = setAsap; Promise._asap = asap; Promise.prototype = { constructor: Promise, /** 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 }); ``` Simple Example -------------- Synchronous Example ```javascript let result; try { result = findResult(); // success } catch(reason) { // failure } ``` Errback Example ```js findResult(function(result, err){ if (err) { // failure } else { // success } }); ``` Promise Example; ```javascript findResult().then(function(result){ // success }, function(reason){ // failure }); ``` Advanced Example -------------- Synchronous Example ```javascript let author, books; try { author = findAuthor(); books = findBooksByAuthor(author); // success } catch(reason) { // failure } ``` Errback Example ```js function foundBooks(books) { } function failure(reason) { } findAuthor(function(author, err){ if (err) { failure(err); // failure } else { try { findBoooksByAuthor(author, function(books, err) { if (err) { failure(err); } else { try { foundBooks(books); } catch(reason) { failure(reason); } } }); } catch(error) { failure(err); } // success } }); ``` Promise Example; ```javascript findAuthor(). then(findBooksByAuthor). then(function(books){ // found books }).catch(function(reason){ // something went wrong }); ``` @method then @param {Function} onFulfilled @param {Function} onRejected Useful for tooling. @return {Promise} */ then: then, /** `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same as the catch block of a try/catch statement. ```js function findAuthor(){ throw new Error('couldn't find that author'); } // synchronous try { findAuthor(); } catch(reason) { // something went wrong } // async with promises findAuthor().catch(function(reason){ // something went wrong }); ``` @method catch @param {Function} onRejection Useful for tooling. @return {Promise} */ 'catch': function _catch(onRejection) { return this.then(null, onRejection); } }; function polyfill() { var local = undefined; if (typeof global !== 'undefined') { local = global; } else if (typeof self !== 'undefined') { local = self; } else { try { local = Function('return this')(); } catch (e) { throw new Error('polyfill failed because global object is unavailable in this environment'); } } var P = local.Promise; if (P) { var promiseToString = null; try { promiseToString = Object.prototype.toString.call(P.resolve()); } catch (e) { // silently ignored } if (promiseToString === '[object Promise]' && !P.cast) { return; } } local.Promise = Promise; } polyfill(); // Strange compat..
