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 var 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 var 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 RSVP.Promise\n @param {function} resolver\n @param {String} label optional string for labeling the promise.\n Useful for tooling.\n @constructor\n */\n function $$rsvp$promise$$Promise(resolver, label) {\n this._id = $$rsvp$promise$$counter++;\n this._label = label;\n this._state = undefined;\n this._result = undefined;\n this._subscribers = [];\n\n if ($$rsvp$config$$config.instrument) {\n $$instrument$$default('created', this);\n }\n\n if ($$$internal$$noop !== resolver) {\n if (!$$utils$$isFunction(resolver)) {\n $$rsvp$promise$$needsResolver();\n }\n\n if (!(this instanceof $$rsvp$promise$$Promise)) {\n $$rsvp$promise$$needsNew();\n }\n\n $$$internal$$initializePromise(this, resolver);\n }\n }\n\n // deprecated\n $$rsvp$promise$$Promise.cast = $$promise$resolve$$default;\n\n $$rsvp$promise$$Promise.all = $$promise$all$$default;\n $$rsvp$promise$$Promise.race = $$promise$race$$default;\n $$rsvp$promise$$Promise.resolve = $$promise$resolve$$default;\n $$rsvp$promise$$Promise.reject = $$promise$reject$$default;\n\n $$rsvp$promise$$Promise.prototype = {\n constructor: $$rsvp$promise$$Promise,\n\n _guidKey: $$rsvp$promise$$guidKey,\n\n _onerror: function (reason) {\n $$rsvp$config$$config.trigger('error', reason);\n },\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 var 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 var 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 @param {String} label optional string for labeling the promise.\n Useful for tooling.\n @return {Promise}\n */\n then: function(onFulfillment, onRejection, label) {\n var parent = this;\n var state = parent._state;\n\n if (state === $$$internal$$FULFILLED && !onFulfillment || state === $$$internal$$REJECTED && !onRejection) {\n if ($$rsvp$config$$config.instrument) {\n $$instrument$$default('chained', this, this);\n }\n return this;\n }\n\n parent._onerror = null;\n\n var child = new this.constructor($$$internal$$noop, label);\n var result = parent._result;\n\n if ($$rsvp$config$$config.instrument) {\n $$instrument$$default('chained', parent, child);\n }\n\n if (state) {\n var callback = arguments[state - 1];\n $$rsvp$config$$config.async(function(){\n $$$internal$$invokeCallback(state, child, callback, result);\n });\n } else {\n $$$internal$$subscribe(parent, child, onFulfillment, onRejection);\n }\n\n return child;\n },\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 @param {String} label optional string for labeling the promise.\n Useful for tooling.\n @return {Promise}\n */\n 'catch': function(onRejection, label) {\n return this.then(null, onRejection, label);\n },\n\n /**\n `finally` will be invoked regardless of the promise's fate just as native\n try/catch/finally behaves\n\n Synchronous example:\n\n ```js\n findAuthor() {\n if (Math.random() > 0.5) {\n throw new Error();\n }\n return new Author();\n }\n\n try {\n return findAuthor();
