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$1 = 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 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} */ /** `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} */ Promise.prototype.catch = function _catch(onRejection) { return this.then(null, onRejection); }; /** `finally` will be invoked regardless of the promise's fate just as native try/catch/finally behaves Synchronous example: ```js findAuthor() { if (Math.random() > 0.5) { throw new Error(); } return new Author(); } try { return findAuthor(); // succeed or fail } catch(error) { return findOtherAuther(); } finally { // always runs // doesn't affect the return value } ``` Asynchronous example: ```js findAuthor().catch(function(reason){ return findOtherAuther(); }).finally(function(){ // author was either found, or not }); ``` @method finally @param {Function} callback @return {Promise} */ Promise.prototype.finally = function _finally(callback) { var promise = this; var constructor = promise.constructor; if (isFunction(callback)) { return promise.then(function (value) { return constructor.resolve(callback()).then(function () { return value; }); }, function (reason) { return constructor.resolve(callback()).then(function () { throw reason; }); }); } return promise.then(callback, callback); }; return Promise; }(); Promise$1.prototype.then = then; Promise$1.all = all; Promise$1.race = race; Promise$1.resolve = resolve$1; Promise$1.reject = reject$1; Promise$1._setScheduler = setScheduler; Promise$1._setAsap = setAsap; Promise$1._asap = asap; /*global self*/ function polyfill() { var local = void 0; 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$1; } // Strange compat..

Assumes that an ES5 platform where, if {@code WeakMap} is * already present, then it conforms to the anticipated ES6 * specification. To run this file on an ES5 or almost ES5 * implementation where the {@code WeakMap} specification does not * quite conform, run repairES5.js first. * *

Even though WeakMapModule is not global, the linter thinks it * is, which is why it is in the overrides list below. * *

NOTE: Before using this WeakMap emulation in a non-SES * environment, see the note below about hiddenRecord. * * @author Mark S. Miller * @requires crypto, ArrayBuffer, Uint8Array, navigator, console * @overrides WeakMap, ses, Proxy * @overrides WeakMapModule */ /** * This {@code WeakMap} emulation is observably equivalent to the * ES-Harmony WeakMap, but with leakier garbage collection properties. * *

As with true WeakMaps, in this emulation, a key does not * retain maps indexed by that key and (crucially) a map does not * retain the keys it indexes. A map by itself also does not retain * the values associated with that map. * *

However, the values associated with a key in some map are * retained so long as that key is retained and those associations are * not overridden. For example, when used to support membranes, all * values exported from a given membrane will live for the lifetime * they would have had in the absence of an interposed membrane. Even * when the membrane is revoked, all objects that would have been * reachable in the absence of revocation will still be reachable, as * far as the GC can tell, even though they will no longer be relevant * to ongoing computation. * *

The API implemented here is approximately the API as implemented * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman, * rather than the offially approved proposal page. TODO(erights): * upgrade the ecmascript WeakMap proposal page to explain this API * change and present to EcmaScript committee for their approval. * *

The first difference between the emulation here and that in * FF6.0a1 is the presence of non enumerable {@code get___, has___, * set___, and delete___} methods on WeakMap instances to represent * what would be the hidden internal properties of a primitive * implementation. Whereas the FF6.0a1 WeakMap.prototype methods * require their {@code this} to be a genuine WeakMap instance (i.e., * an object of {@code [[Class]]} "WeakMap}), since there is nothing * unforgeable about the pseudo-internal method names used here, * nothing prevents these emulated prototype methods from being * applied to non-WeakMaps with pseudo-internal methods of the same * names. * *

Another difference is that our emulated {@code * WeakMap.prototype} is not itself a WeakMap. A problem with the * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap * providing ambient mutability and an ambient communications * channel. Thus, if a WeakMap is already present and has this * problem, repairES5.js wraps it in a safe wrappper in order to * prevent access to this channel. (See * PATCH_MUTABLE_FROZEN_WEAKMAP_PROTO in repairES5.js). */ /** * If this is a full secureable ES5 platform and the ES-Harmony {@code WeakMap} is * absent, install an approximate emulation. * *

If WeakMap is present but cannot store some objects, use our approximate * emulation as a wrapper. * *

If this is almost a secureable ES5 platform, then WeakMap.js * should be run after repairES5.js. * *

Given the known weaknesses of Math.random() on existing * browsers, it does not generate unguessability we can be confident * of. * *

It is the monkey patching logic in this file that is intended * to ensure undiscoverability. The basic idea is that there are * three fundamental means of discovering properties of an object: * The for/in loop, Object.keys(), and Object.getOwnPropertyNames(), * as well as some proposed ES6 extensions that appear on our * whitelist. The first two only discover enumerable properties, and * we only use HIDDEN_NAME to name a non-enumerable property, so the * only remaining threat should be getOwnPropertyNames and some * proposed ES6 extensions that appear on our whitelist. We monkey * patch them to remove HIDDEN_NAME from the list of properties they * returns. * *

TODO(erights): On a platform with built-in Proxies, proxies * could be used to trap and thereby discover the HIDDEN_NAME, so we * need to monkey patch Proxy.create, Proxy.createFunction, etc, in * order to wrap the provided handler with the real handler which * filters out all traps using HIDDEN_NAME. * *

To treat objects as identity-keys with reasonable efficiency * on ES5 by itself (i.e., without any object-keyed collections), we * need to add a hidden property to such key objects when we * can. This raises several issues: *

    *
  • Arranging to add this property to objects before we lose the * chance, and *
  • Hiding the existence of this new property from most * JavaScript code. *
  • Preventing certification theft, where one object is * created falsely claiming to be the key of an association * actually keyed by another object. *
  • Preventing value theft, where untrusted code with * access to a key object but not a weak map nevertheless * obtains access to the value associated with that key in that * weak map. *
* We do so by *
    *
  • Making the name of the hidden property unguessable, so "[]" * indexing, which we cannot intercept, cannot be used to access * a property without knowing the name. *
  • Making the hidden property non-enumerable, so we need not * worry about for-in loops or {@code Object.keys}, *
  • monkey patching those reflective methods that would * prevent extensions, to add this hidden property first, *
  • monkey patching those methods that would reveal this * hidden property. *
* Unfortunately, because of same-origin iframes, we cannot reliably * add this hidden property before an object becomes * non-extensible. Instead, if we encounter a non-extensible object * without a hidden record that we can detect (whether or not it has * a hidden record stored under a name secret to us), then we just * use the key object itself to represent its identity in a brute * force leaky map stored in the weak map, losing all the advantages * of weakness for these. */ function getHiddenRecord(key) { if (key !== Object(key)) { throw new TypeError('Not an object: ' + key); } var hiddenRecord = key[HIDDEN_NAME]; if (hiddenRecord && hiddenRecord.key === key) { return hiddenRecord; } if (!isExtensible(key)) { // Weak map must brute force, as explained in doc-comment above. return void 0; } // The hiddenRecord and the key point directly at each other, via // the "key" and HIDDEN_NAME properties respectively.
