The457      primary way of interacting with a promise is through its `then` method, which458      registers callbacks to receive either a promise's eventual value or the reason459      why the promise cannot be fulfilled.460      Terminology461      -----------462      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.463      - `thenable` is an object or function that defines a `then` method.464      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).465      - `exception` is a value that is thrown using the throw statement.466      - `reason` is a value that indicates why a promise was rejected.467      - `settled` the final resting state of a promise, fulfilled or rejected.468      A promise can be in one of three states: pending, fulfilled, or rejected.469      Promises that are fulfilled have a fulfillment value and are in the fulfilled470      state.  Promises that are rejected have a rejection reason and are in the471      rejected state.  A fulfillment value is never a thenable.472      Promises can also be said to *resolve* a value.  If this value is also a473      promise, then the original promise's settled state will match the value's474      settled state.  So a promise that *resolves* a promise that rejects will475      itself reject, and a promise that *resolves* a promise that fulfills will476      itself fulfill.477      Basic Usage:478      ------------479      ```js480      var promise = new Promise(function(resolve, reject) {481        // on success482        resolve(value);483        // on failure484        reject(reason);485      });486      promise.then(function(value) {487        // on fulfillment488      }, function(reason) {489        // on rejection490      });491      ```492      Advanced Usage:493      ---------------494      Promises shine when abstracting away asynchronous interactions such as495      `XMLHttpRequest`s.496      ```js497      function getJSON(url) {498        return new Promise(function(resolve, reject){499          var xhr = new XMLHttpRequest();500          xhr.open('GET', url);501          xhr.onreadystatechange = handler;502          xhr.responseType = 'json';503          xhr.setRequestHeader('Accept', 'application/json');504          xhr.send();505          function handler() {506            if (this.readyState === this.DONE) {507              if (this.status === 200) {508                resolve(this.response);509              } else {510                reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));511              }512            }513          };514        });515      }516      getJSON('/posts.json').then(function(json) {517        // on fulfillment518      }, function(reason) {519        // on rejection520      });521      ```522      Unlike callbacks, promises are great composable primitives.523      ```js524      Promise.all([525        getJSON('/posts'),526        getJSON('/comments')527      ]).then(function(values){528        values[0] // => postsJSON529        values[1] // => commentsJSON530        return values;531      });532      ```533      @class Promise534      @param {function} resolver535      Useful for tooling.536      @constructor537    */538    function lib$es6$promise$promise$$Promise(resolver) {539      this._id = lib$es6$promise$promise$$counter++;540      this._state = undefined;541      this._result = undefined;542      this._subscribers = [];543      if (lib$es6$promise$$internal$$noop !== resolver) {544        if (!lib$es6$promise$utils$$isFunction(resolver)) {545          lib$es6$promise$promise$$needsResolver();546        }547        if (!(this instanceof lib$es6$promise$promise$$Promise)) {548          lib$es6$promise$promise$$needsNew();549        }550        lib$es6$promise$$internal$$initializePromise(this, resolver);551      }552    }553    lib$es6$promise$promise$$Promise.all = lib$es6$promise$promise$all$$default;554    lib$es6$promise$promise$$Promise.race = lib$es6$promise$promise$race$$default;555    lib$es6$promise$promise$$Promise.resolve = lib$es6$promise$promise$resolve$$default;556    lib$es6$promise$promise$$Promise.reject = lib$es6$promise$promise$reject$$default;557    lib$es6$promise$promise$$Promise._setScheduler = lib$es6$promise$asap$$setScheduler;558    lib$es6$promise$promise$$Promise._setAsap = lib$es6$promise$asap$$setAsap;559    lib$es6$promise$promise$$Promise._asap = lib$es6$promise$asap$$asap;560    lib$es6$promise$promise$$Promise.prototype = {561      constructor: lib$es6$promise$promise$$Promise,562    /**563      The primary way of interacting with a promise is through its `then` method,564      which registers callbacks to receive either a promise's eventual value or the565      reason why the promise cannot be fulfilled.566      ```js567      findUser().then(function(user){568        // user is available569      }, function(reason){570        // user is unavailable, and you are given the reason why571      });572      ```573      Chaining574      --------575      The return value of `then` is itself a promise.

This can be achieved by returning a promise in the614      fulfillment or rejection handler. The downstream promise will then be pending615      until the returned promise is settled. This is called *assimilation*.616      ```js617      findUser().then(function (user) {618        return findCommentsByAuthor(user);619      }).then(function (comments) {620        // The user's comments are now available621      });622      ```623      If the assimliated promise rejects, then the downstream promise will also reject.624      ```js625      findUser().then(function (user) {626        return findCommentsByAuthor(user);627      }).then(function (comments) {628        // If `findCommentsByAuthor` fulfills, we'll have the value here629      }, function (reason) {630        // If `findCommentsByAuthor` rejects, we'll have the reason here631      });632      ```633      Simple Example634      --------------635      Synchronous Example636      ```javascript637      var result;638      try {639        result = findResult();640        // success641      } catch(reason) {642        // failure643      }644      ```645      Errback Example646      ```js647      findResult(function(result, err){648        if (err) {649          // failure650        } else {651          // success652        }653      });654      ```655      Promise Example;656      ```javascript657      findResult().then(function(result){658        // success659      }, function(reason){660        // failure661      });662      ```663      Advanced Example664      --------------665      Synchronous Example666      ```javascript667      var author, books;668      try {669        author = findAuthor();670        books  = findBooksByAuthor(author);671        // success672      } catch(reason) {673        // failure674      }675      ```676      Errback Example677      ```js678      function foundBooks(books) {679      }680      function failure(reason) {681      }682      findAuthor(function(author, err){683        if (err) {684          failure(err);685          // failure686        } else {687          try {688            findBoooksByAuthor(author, function(books, err) {689              if (err) {690                failure(err);691              } else {692                try {693                  foundBooks(books);694                } catch(reason) {695                  failure(reason);696                }697              }698            });699          } catch(error) {700            failure(err);701          }702          // success703        }704      });705      ```706      Promise Example;707      ```javascript708      findAuthor().709        then(findBooksByAuthor).710        then(function(books){711          // found books712      }).catch(function(reason){713        // something went wrong714      });715      ```716      @method then717      @param {Function} onFulfilled718      @param {Function} onRejected719      Useful for tooling.720      @return {Promise}721    */722      then: function(onFulfillment, onRejection) {723        var parent = this;724        var state = parent._state;725        if (state === lib$es6$promise$$internal$$FULFILLED && !onFulfillment || state === lib$es6$promise$$internal$$REJECTED && !onRejection) {726          return this;727        }728        var child = new this.constructor(lib$es6$promise$$internal$$noop);729        var result = parent._result;730        if (state) {731          var callback = arguments[state - 1];732          lib$es6$promise$asap$$asap(function(){733            lib$es6$promise$$internal$$invokeCallback(state, child, callback, result);734          });735        } else {736          lib$es6$promise$$internal$$subscribe(parent, child, onFulfillment, onRejection);737        }738        return child;739      },740    /**741      `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same742      as the catch block of a try/catch statement.743      ```js744      function findAuthor(){745        throw new Error('couldn't find that author');746      }...

The452      primary way of interacting with a promise is through its `then` method, which453      registers callbacks to receive either a promise's eventual value or the reason454      why the promise cannot be fulfilled.455      Terminology456      -----------457      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.458      - `thenable` is an object or function that defines a `then` method.459      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).460      - `exception` is a value that is thrown using the throw statement.461      - `reason` is a value that indicates why a promise was rejected.462      - `settled` the final resting state of a promise, fulfilled or rejected.463      A promise can be in one of three states: pending, fulfilled, or rejected.464      Promises that are fulfilled have a fulfillment value and are in the fulfilled465      state.  Promises that are rejected have a rejection reason and are in the466      rejected state.  A fulfillment value is never a thenable.467      Promises can also be said to *resolve* a value.  If this value is also a468      promise, then the original promise's settled state will match the value's469      settled state.  So a promise that *resolves* a promise that rejects will470      itself reject, and a promise that *resolves* a promise that fulfills will471      itself fulfill.472      Basic Usage:473      ------------474      ```js475      var promise = new Promise(function(resolve, reject) {476        // on success477        resolve(value);478        // on failure479        reject(reason);480      });481      promise.then(function(value) {482        // on fulfillment483      }, function(reason) {484        // on rejection485      });486      ```487      Advanced Usage:488      ---------------489      Promises shine when abstracting away asynchronous interactions such as490      `XMLHttpRequest`s.491      ```js492      function getJSON(url) {493        return new Promise(function(resolve, reject){494          var xhr = new XMLHttpRequest();495          xhr.open('GET', url);496          xhr.onreadystatechange = handler;497          xhr.responseType = 'json';498          xhr.setRequestHeader('Accept', 'application/json');499          xhr.send();500          function handler() {501            if (this.readyState === this.DONE) {502              if (this.status === 200) {503                resolve(this.response);504              } else {505                reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));506              }507            }508          };509        });510      }511      getJSON('/posts.json').then(function(json) {512        // on fulfillment513      }, function(reason) {514        // on rejection515      });516      ```517      Unlike callbacks, promises are great composable primitives.518      ```js519      Promise.all([520        getJSON('/posts'),521        getJSON('/comments')522      ]).then(function(values){523        values[0] // => postsJSON524        values[1] // => commentsJSON525        return values;526      });527      ```528      @class Promise529      @param {function} resolver530      Useful for tooling.531      @constructor532    */533    function lib$es6$promise$promise$$Promise(resolver) {534      this._id = lib$es6$promise$promise$$counter++;535      this._state = undefined;536      this._result = undefined;537      this._subscribers = [];538      if (lib$es6$promise$$internal$$noop !== resolver) {539        if (!lib$es6$promise$utils$$isFunction(resolver)) {540          lib$es6$promise$promise$$needsResolver();541        }542        if (!(this instanceof lib$es6$promise$promise$$Promise)) {543          lib$es6$promise$promise$$needsNew();544        }545        lib$es6$promise$$internal$$initializePromise(this, resolver);546      }547    }548    lib$es6$promise$promise$$Promise.all = lib$es6$promise$promise$all$$default;549    lib$es6$promise$promise$$Promise.race = lib$es6$promise$promise$race$$default;550    lib$es6$promise$promise$$Promise.resolve = lib$es6$promise$promise$resolve$$default;551    lib$es6$promise$promise$$Promise.reject = lib$es6$promise$promise$reject$$default;552    lib$es6$promise$promise$$Promise._setScheduler = lib$es6$promise$asap$$setScheduler;553    lib$es6$promise$promise$$Promise._setAsap = lib$es6$promise$asap$$setAsap;554    lib$es6$promise$promise$$Promise._asap = lib$es6$promise$asap$$asap;555    lib$es6$promise$promise$$Promise.prototype = {556      constructor: lib$es6$promise$promise$$Promise,557    /**558      The primary way of interacting with a promise is through its `then` method,559      which registers callbacks to receive either a promise's eventual value or the560      reason why the promise cannot be fulfilled.561      ```js562      findUser().then(function(user){563        // user is available564      }, function(reason){565        // user is unavailable, and you are given the reason why566      });567      ```568      Chaining569      --------570      The return value of `then` is itself a promise.

This is called *assimilation*.611      ```js612      findUser().then(function (user) {613        return findCommentsByAuthor(user);614      }).then(function (comments) {615        // The user's comments are now available616      });617      ```618      If the assimliated promise rejects, then the downstream promise will also reject.619      ```js620      findUser().then(function (user) {621        return findCommentsByAuthor(user);622      }).then(function (comments) {623        // If `findCommentsByAuthor` fulfills, we'll have the value here624      }, function (reason) {625        // If `findCommentsByAuthor` rejects, we'll have the reason here626      });627      ```628      Simple Example629      --------------630      Synchronous Example631      ```javascript632      var result;633      try {634        result = findResult();635        // success636      } catch(reason) {637        // failure638      }639      ```640      Errback Example641      ```js642      findResult(function(result, err){643        if (err) {644          // failure645        } else {646          // success647        }648      });649      ```650      Promise Example;651      ```javascript652      findResult().then(function(result){653        // success654      }, function(reason){655        // failure656      });657      ```658      Advanced Example659      --------------660      Synchronous Example661      ```javascript662      var author, books;663      try {664        author = findAuthor();665        books  = findBooksByAuthor(author);666        // success667      } catch(reason) {668        // failure669      }670      ```671      Errback Example672      ```js673      function foundBooks(books) {674      }675      function failure(reason) {676      }677      findAuthor(function(author, err){678        if (err) {679          failure(err);680          // failure681        } else {682          try {683            findBoooksByAuthor(author, function(books, err) {684              if (err) {685                failure(err);686              } else {687                try {688                  foundBooks(books);689                } catch(reason) {690                  failure(reason);691                }692              }693            });694          } catch(error) {695            failure(err);696          }697          // success698        }699      });700      ```701      Promise Example;702      ```javascript703      findAuthor().704        then(findBooksByAuthor).705        then(function(books){706          // found books707      }).catch(function(reason){708        // something went wrong709      });710      ```711      @method then712      @param {Function} onFulfilled713      @param {Function} onRejected714      Useful for tooling.715      @return {Promise}716    */717      then: function(onFulfillment, onRejection) {718        var parent = this;719        var state = parent._state;720        if (state === lib$es6$promise$$internal$$FULFILLED && !onFulfillment || state === lib$es6$promise$$internal$$REJECTED && !onRejection) {721          return this;722        }723        var child = new this.constructor(lib$es6$promise$$internal$$noop);724        var result = parent._result;725        if (state) {726          var callback = arguments[state - 1];727          lib$es6$promise$asap$$asap(function(){728            lib$es6$promise$$internal$$invokeCallback(state, child, callback, result);729          });730        } else {731          lib$es6$promise$$internal$$subscribe(parent, child, onFulfillment, onRejection);732        }733        return child;734      },735    /**736      `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same737      as the catch block of a try/catch statement.738      ```js739      function findAuthor(){740        throw new Error('couldn't find that author');741      }...
