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..

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. * *

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.
