      `Promise.all` accepts an array of promises, and returns a new promise which
      is fulfilled with an array of fulfillment values for the passed promises, or
      rejected with the reason of the first passed promise to be rejected. It casts all
      elements of the passed iterable to promises as it runs this algorithm.
    
      Example:
    
      ```javascript
      let promise1 = resolve(1);
      let promise2 = resolve(2);
      let promise3 = resolve(3);
      let promises = [ promise1, promise2, promise3 ];
    
      Promise.all(promises).then(function(array){
        // The array here would be [ 1, 2, 3 ];
      });
      ```
    
      If any of the `promises` given to `all` are rejected, the first promise
      that is rejected will be given as an argument to the returned promises's
      rejection handler. For example:
    
      Example:
    
      ```javascript
      let promise1 = resolve(1);
      let promise2 = reject(new Error("2"));
      let promise3 = reject(new Error("3"));
      let promises = [ promise1, promise2, promise3 ];
    
      Promise.all(promises).then(function(array){
        // Code here never runs because there are rejected promises!
      }, function(error) {
        // error.message === "2"
      });
      ```
    
      @method all

      fulfilled, or rejected if any of them become rejected.

    /**
      `Promise.race` returns a new promise which is settled in the same way as the
      first passed promise to settle.
    
      Example:
    
      ```javascript
      let promise1 = new Promise(function(resolve, reject){
        setTimeout(function(){
          resolve('promise 1');
        }, 200);
      });
    
      let promise2 = new Promise(function(resolve, reject){
        setTimeout(function(){
          resolve('promise 2');
        }, 100);
      });
    
      Promise.race([promise1, promise2]).then(function(result){
        // result === 'promise 2' because it was resolved before promise1
        // was resolved.
      });
      ```
    
      `Promise.race` is deterministic in that only the state of the first
      settled promise matters. For example, even if other promises given to the
      `promises` array argument are resolved, but the first settled promise has
      become rejected before the other promises became fulfilled, the returned
      promise will become rejected:
    
      ```javascript
      let promise1 = new Promise(function(resolve, reject){
        setTimeout(function(){
          resolve('promise 1');
        }, 200);
      });
    
      let promise2 = new Promise(function(resolve, reject){
        setTimeout(function(){
          reject(new Error('promise 2'));
        }, 100);
      });
    
      Promise.race([promise1, promise2]).then(function(result){
        // Code here never runs
      }, function(reason){
        // reason.message === 'promise 2' because promise 2 became rejected before
        // promise 1 became fulfilled
      });
      ```
    
      An example real-world use case is implementing timeouts:
    
      ```javascript
      Promise.race([ajax('foo.json'), timeout(5000)])
      ```
    
      @method race

    /**
      Promise objects represent the eventual result of an asynchronous operation. 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
        });
        ```

        --------------
         Synchronous Example
         ```javascript
        let result;
         try {

/**
 * An extension of the "same-value" algorithm as [described for use by ES6 Map
 * and Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#Key_equality)
 *
 * NaN is considered the same as NaN, however -0 and 0 are considered the same
 * value, which is different from the algorithm described by
 * [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is).
 *
 * This is extended further to allow Objects to describe the values they
 * represent, by way of `valueOf` or `equals` (and `hashCode`).
 *
 * Note: because of this extension, the key equality of Immutable.Map and the
 * value equality of Immutable.Set will differ from ES6 Map and Set.
 *
 * ### Defining custom values
 *
 * The easiest way to describe the value an object represents is by implementing
 * `valueOf`. For example, `Date` represents a value by returning a unix
 * timestamp for `valueOf`:
 *
 *     var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...
 *     var date2 = new Date(1234567890000);
 *     date1.valueOf(); // 1234567890000
 *     assert( date1 !== date2 );
 *     assert( Immutable.is( date1, date2 ) );
 *
 * Note: overriding `valueOf` may have other implications if you use this object
 * where JavaScript expects a primitive, such as implicit string coercion.
 *
 * For more complex types, especially collections, implementing `valueOf` may
 * not be performant. An alternative is to implement `equals` and `hashCode`.
 *
 * `equals` takes another object, presumably of similar type, and returns true
 * if it is equal. Equality is symmetrical, so the same result should be
 * returned if this and the argument are flipped.
 *
 *     assert( a.equals(b) === b.equals(a) );
 *
 * `hashCode` returns a 32bit integer number representing the object which will
 * be used to determine how to store the value object in a Map or Set. You must
 * provide both or neither methods, one must not exist without the other.
 *
 * Also, an important relationship between these methods must be upheld: if two
 * values are equal, they *must* return the same hashCode. If the values are not
 * equal, they might have the same hashCode; this is called a hash collision,
 * and while undesirable for performance reasons, it is acceptable.
 *
 *     if (a.equals(b)) {
 *       assert( a.hashCode() === b.hashCode() );
 *     }
 *
 * All Immutable collections are Value Objects: they implement `equals()`
 * and `hashCode()`.

// Generated by dart2js (NullSafetyMode.sound, trust primitives, omit checks, lax runtime type, csp, deferred-serialization, intern-composite-values), the Dart to JavaScript compiler version: 3.1.5.
// The code supports the following hooks:
// dartPrint(message):
//    if this function is defined it is called instead of the Dart [print]
//    method.
//
// dartMainRunner(main, args):
//    if this function is defined, the Dart [main] method will not be invoked
//    directly. Instead, a closure that will invoke [main], and its arguments
//    [args] is passed to [dartMainRunner].
//
// dartDeferredLibraryLoader(uri, successCallback, errorCallback, loadId, loadPriority):
//    if this function is defined, it will be called when a deferred library
//    is loaded. It should load and eval the javascript of `uri`, and call
//    successCallback. If it fails to do so, it should call errorCallback with
//    an error. The loadId argument is the deferred import that resulted in
//    this uri being loaded. The loadPriority argument is the priority the
//    library should be loaded with as specified in the code via the
//    load-priority annotation (0: normal, 1: high).
//
// dartCallInstrumentation(id, qualifiedName):
//    if this function is defined, it will be called at each entry of a
//    method or constructor. Used only when compiling programs with
//    --experiment-call-instrumentation.

 * already parsed to an object). According to the spec, source maps have the
 * following attributes:
 *
 *   - version: Which version of the source map spec this map is following.
 *   - sources: An array of URLs to the original source files.
 *   - names: An array of identifiers which can be referrenced by individual mappings.
 *   - sourceRoot: Optional. The URL root from which all sources are relative.
 *   - sourcesContent: Optional. An array of contents of the original source files.
 *   - mappings: A string of base64 VLQs which contain the actual mappings.
 *   - file: Optional. The generated file this source map is associated with.
 *
 * Here is an example source map, taken from the source map spec[0]:
 *
 *     {
 *       version : 3,

 *       names: ["src", "maps", "are", "fun"],
 *       mappings: "AA,AB;;ABCDE;"

 *
 * The second parameter, if given, is a string whose value is the URL
 * at which the source map was found.  This URL is used to compute the
 * sources array.

/**
 * An IndexedSourceMapConsumer instance represents a parsed source map which
 * we can query for information. It differs from BasicSourceMapConsumer in
 * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
 * input.
 *
 * The first parameter is a raw source map (either as a JSON string, or already
 * parsed to an object). According to the spec for indexed source maps, they
 * have the following attributes:
 *
 *   - version: Which version of the source map spec this map is following.
 *   - file: Optional. The generated file this source map is associated with.
 *   - sections: A list of section definitions.
 *
 * Each value under the "sections" field has two fields:
 *   - offset: The offset into the original specified at which this section
 *       begins to apply, defined as an object with a "line" and "column"
 *       field.
 *   - map: A source map definition. This source map could also be indexed,
 *       but doesn't have to be.
 *
 * Instead of the "map" field, it's also possible to have a "url" field
 * specifying a URL to retrieve a source map from, but that's currently
 * unsupported.
 *
 * Here's an example source map, taken from the source map spec[0], but
 * modified to omit a section which uses the "url" field.
 *
 *  {
 *    version : 3,
 *    file: "app.js",
 *    sections: [{
 *      offset: {line:100, column:10},
 *      map: {
 *        version : 3,
 *        file: "section.js",
 *        sources: ["foo.js", "bar.js"],
 *        names: ["src", "maps", "are", "fun"],
 *        mappings: "AAAA,E;;ABCDE;"
 *      }
 *    }],
 *  }
 *
 * The second parameter, if given, is a string whose value is the URL
 * at which the source map was found.  This URL is used to compute the
 * sources array.
 *
