The\n primary way of interacting with a promise is through its `then` method, which\n registers callbacks to receive either a promise's eventual value or the reason\n why the promise cannot be fulfilled.\n \n Terminology\n -----------\n \n - `promise` is an object or function with a `then` method whose behavior conforms to this specification.\n - `thenable` is an object or function that defines a `then` method.\n - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).\n - `exception` is a value that is thrown using the throw statement.\n - `reason` is a value that indicates why a promise was rejected.\n - `settled` the final resting state of a promise, fulfilled or rejected.\n \n A promise can be in one of three states: pending, fulfilled, or rejected.\n \n Promises that are fulfilled have a fulfillment value and are in the fulfilled\n state. Promises that are rejected have a rejection reason and are in the\n rejected state. A fulfillment value is never a thenable.\n \n Promises can also be said to *resolve* a value. If this value is also a\n promise, then the original promise's settled state will match the value's\n settled state. So a promise that *resolves* a promise that rejects will\n itself reject, and a promise that *resolves* a promise that fulfills will\n itself fulfill.\n \n \n Basic Usage:\n ------------\n \n ```js\n let promise = new Promise(function(resolve, reject) {\n // on success\n resolve(value);\n \n // on failure\n reject(reason);\n });\n \n promise.then(function(value) {\n // on fulfillment\n }, function(reason) {\n // on rejection\n });\n ```\n \n Advanced Usage:\n ---------------\n \n Promises shine when abstracting away asynchronous interactions such as\n `XMLHttpRequest`s.\n \n ```js\n function getJSON(url) {\n return new Promise(function(resolve, reject){\n let xhr = new XMLHttpRequest();\n \n xhr.open('GET', url);\n xhr.onreadystatechange = handler;\n xhr.responseType = 'json';\n xhr.setRequestHeader('Accept', 'application/json');\n xhr.send();\n \n function handler() {\n if (this.readyState === this.DONE) {\n if (this.status === 200) {\n resolve(this.response);\n } else {\n reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));\n }\n }\n };\n });\n }\n \n getJSON('/posts.json').then(function(json) {\n // on fulfillment\n }, function(reason) {\n // on rejection\n });\n ```\n \n Unlike callbacks, promises are great composable primitives.\n \n ```js\n Promise.all([\n getJSON('/posts'),\n getJSON('/comments')\n ]).then(function(values){\n values[0] // => postsJSON\n values[1] // => commentsJSON\n \n return values;\n });\n ```\n \n @class Promise\n @param {function} resolver\n Useful for tooling.\n @constructor\n */\n function Promise(resolver) {\n this[PROMISE_ID] = nextId();\n this._result = this._state = undefined;\n this._subscribers = [];\n\n if (noop !== resolver) {\n typeof resolver !== 'function' && needsResolver();\n this instanceof Promise ? initializePromise(this, resolver) : needsNew();\n }\n }\n\n Promise.all = all;\n Promise.race = race;\n Promise.resolve = resolve;\n Promise.reject = reject;\n Promise._setScheduler = setScheduler;\n Promise._setAsap = setAsap;\n Promise._asap = asap;\n\n Promise.prototype = {\n constructor: Promise,\n\n /**\n The primary way of interacting with a promise is through its `then` method,\n which registers callbacks to receive either a promise's eventual value or the\n reason why the promise cannot be fulfilled.\n \n ```js\n findUser().then(function(user){\n // user is available\n }, function(reason){\n // user is unavailable, and you are given the reason why\n });\n ```\n \n Chaining\n --------\n \n The return value of `then` is itself a promise. This second, 'downstream'\n promise is resolved with the return value of the first promise's fulfillment\n or rejection handler, or rejected if the handler throws an exception.\n \n ```js\n findUser().then(function (user) {\n return user.name;\n }, function (reason) {\n return 'default name';\n }).then(function (userName) {\n // If `findUser` fulfilled, `userName` will be the user's name, otherwise it\n // will be `'default name'`\n });\n \n findUser().then(function (user) {\n throw new Error('Found user, but still unhappy');\n }, function (reason) {\n throw new Error('`findUser` rejected and we're unhappy');\n }).then(function (value) {\n // never reached\n }, function (reason) {\n // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.\n // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.\n });\n ```\n If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.\n \n ```js\n findUser().then(function (user) {\n throw new PedagogicalException('Upstream error');\n }).then(function (value) {\n // never reached\n }).then(function (value) {\n // never reached\n }, function (reason) {\n // The `PedgagocialException` is propagated all the way down to here\n });\n ```\n \n Assimilation\n ------------\n \n Sometimes the value you want to propagate to a downstream promise can only be\n retrieved asynchronously. This can be achieved by returning a promise in the\n fulfillment or rejection handler. The downstream promise will then be pending\n until the returned promise is settled. This is called *assimilation*.\n \n ```js\n findUser().then(function (user) {\n return findCommentsByAuthor(user);\n }).then(function (comments) {\n // The user's comments are now available\n });\n ```\n \n If the assimliated promise rejects, then the downstream promise will also reject.\n \n ```js\n findUser().then(function (user) {\n return findCommentsByAuthor(user);\n }).then(function (comments) {\n // If `findCommentsByAuthor` fulfills, we'll have the value here\n }, function (reason) {\n // If `findCommentsByAuthor` rejects, we'll have the reason here\n });\n ```\n \n Simple Example\n --------------\n \n Synchronous Example\n \n ```javascript\n let result;\n \n try {\n result = findResult();\n // success\n } catch(reason) {\n // failure\n }\n ```\n \n Errback Example\n \n ```js\n findResult(function(result, err){\n if (err) {\n // failure\n } else {\n // success\n }\n });\n ```\n \n Promise Example;\n \n ```javascript\n findResult().then(function(result){\n // success\n }, function(reason){\n // failure\n });\n ```\n \n Advanced Example\n --------------\n \n Synchronous Example\n \n ```javascript\n let author, books;\n \n try {\n author = findAuthor();\n books = findBooksByAuthor(author);\n // success\n } catch(reason) {\n // failure\n }\n ```\n \n Errback Example\n \n ```js\n \n function foundBooks(books) {\n \n }\n \n function failure(reason) {\n \n }\n \n findAuthor(function(author, err){\n if (err) {\n failure(err);\n // failure\n } else {\n try {\n findBoooksByAuthor(author, function(books, err) {\n if (err) {\n failure(err);\n } else {\n try {\n foundBooks(books);\n } catch(reason) {\n failure(reason);\n }\n }\n });\n } catch(error) {\n failure(err);\n }\n // success\n }\n });\n ```\n \n Promise Example;\n \n ```javascript\n findAuthor().\n then(findBooksByAuthor).\n then(function(books){\n // found books\n }).catch(function(reason){\n // something went wrong\n });\n ```\n \n @method then\n @param {Function} onFulfilled\n @param {Function} onRejected\n Useful for tooling.\n @return {Promise}\n */\n then: then,\n\n /**\n `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same\n as the catch block of a try/catch statement.\n \n ```js\n function findAuthor(){\n throw new Error('couldn't find that author');\n }\n \n // synchronous\n try {\n findAuthor();\n } catch(reason) {\n // something went wrong\n }\n \n // async with promises\n findAuthor().catch(function(reason){\n // something went wrong\n });\n ```\n \n @method catch\n @param {Function} onRejection\n Useful for tooling.\n @return {Promise}\n */\n 'catch': function _catch(onRejection) {\n return this.then(null, onRejection);\n }\n };\n\n function polyfill() {\n var local = undefined;\n\n if (typeof global !== 'undefined') {\n local = global;\n } else if (typeof self !== 'undefined') {\n local = self;\n } else {\n try {\n local = Function('return this')();\n } catch (e) {\n throw new Error('polyfill failed because global object is unavailable in this environment');\n }\n }\n\n var P = local.Promise;\n\n if (P) {\n var promiseToString = null;\n try {\n promiseToString = Object.prototype.toString.call(P.resolve());\n } catch (e) {\n // silently ignored\n }\n\n if (promiseToString === '[object Promise]' && !P.cast) {\n return;\n }\n }\n\n local.Promise = Promise;\n }\n\n // Strange compat..\n Promise.polyfill = polyfill;\n Promise.Promise = Promise;\n\n return Promise;\n});\n//# sourceMappingURL=es6-promise.map\n/* WEBPACK VAR INJECTION */}.call(exports, __webpack_require__(16), (function() { return this; }())))\n\n/*****************\n ** WEBPACK FOOTER\n ** ./~/es6-promise/dist/es6-promise.js\n ** module id = 15\n ** module chunks = 0\n **/\n//# sourceURL=webpack:///./~/es6-promise/dist/es6-promise.js?");
