/**
  `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

/**
  `Promise.race` returns a new promise which is settled in the same way as the

  Example:

  ```javascript
  let promise1 = new Promise(function(resolve, reject){

      resolve('promise 1');
    }, 200);
  });

  let promise2 = new Promise(function(resolve, reject){

  });

  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
  });
  ```

/**
  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

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

      // success

      // failure
    });

/*
 * Can this value be deleted? We can delete any empty object (null, undefined, [], {})
 * EXCEPT empty data arrays, {} inside an array, or anything INSIDE an *args* array.
 *
 * Info arrays can be safely deleted, but not deleting them has no ill effects other
 * than leaving a trace or layout object with some cruft in it.
 *
 * Deleting data arrays can change the meaning of the object, as `[]` means there is
 * data for this attribute, it's just empty right now while `undefined` means the data
 * should be filled in with defaults to match other data arrays.
 *
 * `{}` inside an array means "the default object" which is clearly different from
 * popping it off the end of the array, or setting it `undefined` inside the array.
 *
 * *args* arrays get passed directly to API methods and we should respect precisely
 * what the user has put there - although if the whole *args* array is empty it's fine
 * to delete that.
 *
 * So we do some simple tests here to find known non-data arrays but don't worry too
 * much about not deleting some arrays that would actually be safe to delete.

 * applyContainerArrayChanges: for managing arrays of layout components in relayout

 * (as prepared in _relayout):
 *
 * add an empty obj -> {'annotations[2]': 'add'} -> {2: {'': 'add'}}
 * add a specific obj -> {'annotations[2]': {attrs}} -> {2: {'': {attrs}}}
 * delete an obj -> {'annotations[2]': 'remove'} -> {2: {'': 'remove'}}
 *               -> {'annotations[2]': null} -> {2: {'': null}}
 * delete the whole array -> {'annotations': 'remove'} -> {'': {'': 'remove'}}
 *                        -> {'annotations': null} -> {'': {'': null}}
 * edit an object -> {'annotations[2].text': 'boo'} -> {2: {'text': 'boo'}}
 *
 * You can combine many edits to different objects. Objects are added and edited
 * in ascending order, then removed in descending order.
 * For example, starting with [a, b, c], if you want to:
 * - replace b with d:
 *   {'annotations[1]': d, 'annotations[2]': null} (b is item 2 after adding d)
 * - add a new item d between a and b, and edit b:
 *    {'annotations[1]': d, 'annotations[2].x': newX} (b is item 2 after adding d)
 * - delete b and edit c:
 *    {'annotations[1]': null, 'annotations[2].x': newX} (c is edited before b is removed)
 *
 * You CANNOT combine adding/deleting an item at index `i` with edits to the same index `i`
 * You CANNOT combine replacing/deleting the whole array with anything else (for the same array).
 *
 * @param {HTMLDivElement} gd
 *  the DOM element of the graph container div

 *      a single frame, array of frames, or group to which to animate. The intent is
 *      inferred by the type of the input. Valid inputs are:
 *
 *      - string, e.g. 'groupname': animate all frames of a given `group` in the order
 *            in which they are defined via `Plotly.addFrames`.
 *
 *      - array of strings, e.g. ['frame1', frame2']: a list of frames by name to which
 *            to animate in sequence
 *
 *      - object: {data: ...}: a frame definition to which to animate. The frame is not
 *            and does not need to be added via `Plotly.addFrames`. It may contain any of
 *            the properties of a frame, including `data`, `layout`, and `traces`. The
 *            frame is used as provided and does not use the `baseframe` property.
 *
 *      - array of objects, e.g. [{data: ...}, {data: ...}]: a list of frame objects,
 *            each following the same rules as a single `object`.
 *
 * @param {object} animationOpts
 *      configuration for the animation
