  `Promise.resolve` returns a promise that will become resolved with the

  ```javascript
  let promise = new Promise(function(resolve, reject){

  });

  promise.then(function(value){

  promise.then(function(value){

  @static

/**
  `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
  @static
  @param {Array} entries array of promises
  @param {String} label optional string for labeling the promise.
  Useful for tooling.
  @return {Promise} promise that is fulfilled when all `promises` have been
  fulfilled, or rejected if any of them become rejected.
  @static
*/
function all(entries) {
  return new Enumerator(this, entries).promise;
}

/**
  `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
  @static
  @param {Array} promises array of promises to observe
  Useful for tooling.
  @return {Promise} a promise which settles in the same way as the first passed
  promise to settle.
*/
function race(entries) {
  /*jshint validthis:true */
  var Constructor = this;

  if (!isArray(entries)) {
    return new Constructor(function (_, reject) {
      return reject(new TypeError('You must pass an array to race.'));
    });
  } else {
    return new Constructor(function (resolve, reject) {
      var length = entries.length;
      for (var i = 0; i < length; i++) {
        Constructor.resolve(entries[i]).then(resolve, reject);
      }
    });
  }
}

/**
  `Promise.reject` returns a promise rejected with the passed `reason`.
  It is shorthand for the following:

  promise.then(function(value){
    // Code here doesn't run because the promise is rejected!

/**
  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;
  });
  ```

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();
  }
}

Promise.all = all;
Promise.race = race;
Promise.resolve = resolve;
Promise.reject = reject;
Promise._setScheduler = setScheduler;
Promise._setAsap = setAsap;
Promise._asap = asap;

Promise.prototype = {
  constructor: Promise,

  /**
    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
    });
    ```
  
    Simple Example

    let result;
  
    try {
      result = findResult();
      // success
    } catch(reason) {
      // failure
    }
    ```
  
    Errback Example
  
    ```js
    findResult(function(result, err){
      if (err) {
        // failure
      } else {

/**
 * visit() will walk through an AST using a depth first traversal, calling
 * the visitor's enter function at each node in the traversal, and calling the
 * leave function after visiting that node and all of its child nodes.
 *
 * By returning different values from the enter and leave functions, the
 * behavior of the visitor can be altered, including skipping over a sub-tree of
 * the AST (by returning false), editing the AST by returning a value or null
 * to remove the value, or to stop the whole traversal by returning BREAK.
 *
 * When using visit() to edit an AST, the original AST will not be modified, and
 * a new version of the AST with the changes applied will be returned from the
 * visit function.
 *
 *     const editedAST = visit(ast, {
 *       enter(node, key, parent, path, ancestors) {
 *         // @return
 *         //   undefined: no action
 *         //   false: skip visiting this node
 *         //   visitor.BREAK: stop visiting altogether
 *         //   null: delete this node
 *         //   any value: replace this node with the returned value
 *       },
 *       leave(node, key, parent, path, ancestors) {

 *         //   null: delete this node
 *         //   any value: replace this node with the returned value
 *       }
 *     });
 *
 * Alternatively to providing enter() and leave() functions, a visitor can
 * instead provide functions named the same as the kinds of AST nodes, or
 * enter/leave visitors at a named key, leading to four permutations of
 * visitor API:
 *
 * 1) Named visitors triggered when entering a node a specific kind.
 *
 *     visit(ast, {
 *       Kind(node) {
 *         // enter the "Kind" node
 *       }
 *     })
 *
 * 2) Named visitors that trigger upon entering and leaving a node of
 *    a specific kind.
 *
 *     visit(ast, {
 *       Kind: {
 *         enter(node) {
 *           // enter the "Kind" node
 *         }
 *         leave(node) {
 *           // leave the "Kind" node
 *         }
 *       }
 *     })
 *
 * 3) Generic visitors that trigger upon entering and leaving any node.
 *
 *     visit(ast, {
 *       enter(node) {
 *         // enter any node
 *       },
 *       leave(node) {
 *         // leave any node
 *       }
 *     })
 *
 * 4) Parallel visitors for entering and leaving nodes of a specific kind.
 *
 *     visit(ast, {
 *       enter: {
 *         Kind(node) {
 *           // enter the "Kind" node
 *         }
 *       },
 *       leave: {
 *         Kind(node) {

/**
 * Schema Definition
 *
 * A Schema is created by supplying the root types of each type of operation,
 * query and mutation (optional). A schema definition is then supplied to the
 * validator and executor.
 *
 * Example:
 *
 *     const MyAppSchema = new GraphQLSchema({
 *       query: MyAppQueryRootType,
 *       mutation: MyAppMutationRootType,
 *     })
 *
 * Note: If an array of `directives` are provided to GraphQLSchema, that will be
 * the exact list of directives represented and allowed. If `directives` is not
 * provided then a default set of the specified directives (e.g. @include and
 * @skip) will be used. If you wish to provide *additional* directives to these
 * specified directives, you must explicitly declare them. Example:
 *
 *     const MyAppSchema = new GraphQLSchema({
 *       ...
 *       directives: specifiedDirectives.concat([ myCustomDirective ]),
 *     })
 *

   * will not have any effect on the `dispatch()` that is currently in progress.
   * However, the next `dispatch()` call, whether nested or not, will use a more
   * recent snapshot of the subscription list.
   *
   * 2. The listener should not expect to see all state changes, as the state
   * might have been updated multiple times during a nested `dispatch()` before
   * the listener is called. It is, however, guaranteed that all subscribers
   * registered before the `dispatch()` started will be called with the latest
   * state by the time it exits.
   *
   * @param {Function} listener A callback to be invoked on every dispatch.
   * @returns {Function} A function to remove this change listener.
