/**
  `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.

function all(entries) {

/**
  `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){

      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.race([ajax('foo.json'), timeout(5000)])
  ```

/**
  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
    });
    ```

* Set settings for this index

* - minWordSizefor1Typo: (integer) the minimum number of characters to accept one typo (default = 3).
* - minWordSizefor2Typos: (integer) the minimum number of characters to accept two typos (default = 7).
* - hitsPerPage: (integer) the number of hits per page (default = 10).
* - attributesToRetrieve: (array of strings) default list of attributes to retrieve in objects.
*   If set to null, all attributes are retrieved.
* - attributesToHighlight: (array of strings) default list of attributes to highlight.
*   If set to null, all indexed attributes are highlighted.
* - attributesToSnippet**: (array of strings) default list of attributes to snippet alongside the number
* of words to return (syntax is attributeName:nbWords).
*   By default no snippet is computed. If set to null, no snippet is computed.
* - attributesToIndex: (array of strings) the list of fields you want to index.
*   If set to null, all textual and numerical attributes of your objects are indexed,
*   but you should update it to get optimal results.
*   This parameter has two important uses:
*     - Limit the attributes to index: For example if you store a binary image in base64,
*     you want to store it and be able to
*       retrieve it but you don't want to search in the base64 string.
*     - Control part of the ranking*: (see the ranking parameter for full explanation)
*     Matches in attributes at the beginning of
*       the list will be considered more important than matches in attributes further down the list.
*       In one attribute, matching text at the beginning of the attribute will be
*       considered more important than text after, you can disable
*       this behavior if you add your attribute inside `unordered(AttributeName)`,
*       for example attributesToIndex: ["title", "unordered(text)"].
* - attributesForFaceting: (array of strings) The list of fields you want to use for faceting.
*   All strings in the attribute selected for faceting are extracted and added as a facet.
*   If set to null, no attribute is used for faceting.
* - attributeForDistinct: (string) The attribute name used for the Distinct feature.
* This feature is similar to the SQL "distinct" keyword: when enabled
*   in query with the distinct=1 parameter, all hits containing a duplicate
*   value for this attribute are removed from results.
*   For example, if the chosen attribute is show_name and several hits have
*   the same value for show_name, then only the best one is kept and others are removed.
* - ranking: (array of strings) controls the way results are sorted.
*   We have six available criteria:
*    - typo: sort according to number of typos,
*    - geo: sort according to decreassing distance when performing a geo-location based search,
*    - proximity: sort according to the proximity of query words in hits,
*    - attribute: sort according to the order of attributes defined by attributesToIndex,
*    - exact:
*        - if the user query contains one word: sort objects having an attribute
*        that is exactly the query word before others.
*          For example if you search for the "V" TV show, you want to find it
*          with the "V" query and avoid to have all popular TV
*          show starting by the v letter before it.
*        - if the user query contains multiple words: sort according to the
*        number of words that matched exactly (and not as a prefix).
*    - custom: sort according to a user defined formula set in **customRanking** attribute.
*   The standard order is ["typo", "geo", "proximity", "attribute", "exact", "custom"]
* - customRanking: (array of strings) lets you specify part of the ranking.
*   The syntax of this condition is an array of strings containing attributes
*   prefixed by asc (ascending order) or desc (descending order) operator.
*   For example `"customRanking" => ["desc(population)", "asc(name)"]`
* - queryType: Select how the query words are interpreted, it can be one of the following value:
*   - prefixAll: all query words are interpreted as prefixes,
*   - prefixLast: only the last word is interpreted as a prefix (default behavior),
*   - prefixNone: no query word is interpreted as a prefix. This option is not recommended.
* - highlightPreTag: (string) Specify the string that is inserted before
* the highlighted parts in the query result (default to "<em>").
* - highlightPostTag: (string) Specify the string that is inserted after
* the highlighted parts in the query result (default to "</em>").
* - optionalWords: (array of strings) Specify a list of words that should
* be considered as optional when found in the query.

* @param args (optional) if set, contains an object with query parameters:
* - page: (integer) Pagination parameter used to select the page to retrieve.
*                   Page is zero-based and defaults to 0. Thus,
*                   to retrieve the 10th page you need to set page=9
* - hitsPerPage: (integer) Pagination parameter used to select the number of hits per page. Defaults to 20.
* - attributesToRetrieve: a string that contains the list of object attributes
* you want to retrieve (let you minimize the answer size).
*   Attributes are separated with a comma (for example "name,address").
*   You can also use an array (for example ["name","address"]).
*   By default, all attributes are retrieved. You can also use '*' to retrieve all
*   values when an attributesToRetrieve setting is specified for your index.
* - attributesToHighlight: a string that contains the list of attributes you
*   want to highlight according to the query.
*   Attributes are separated by a comma. You can also use an array (for example ["name","address"]).
*   If an attribute has no match for the query, the raw value is returned.
*   By default all indexed text attributes are highlighted.
*   You can use `*` if you want to highlight all textual attributes.
*   Numerical attributes are not highlighted.
*   A matchLevel is returned for each highlighted attribute and can contain:
*      - full: if all the query terms were found in the attribute,
*      - partial: if only some of the query terms were found,
*      - none: if none of the query terms were found.
* - attributesToSnippet: a string that contains the list of attributes to snippet alongside
* the number of words to return (syntax is `attributeName:nbWords`).
*    Attributes are separated by a comma (Example: attributesToSnippet=name:10,content:10).
*    You can also use an array (Example: attributesToSnippet: ['name:10','content:10']).
*    By default no snippet is computed.
* - minWordSizefor1Typo: the minimum number of characters in a query word to accept one typo in this word.
* Defaults to 3.
* - minWordSizefor2Typos: the minimum number of characters in a query word
* to accept two typos in this word. Defaults to 7.
* - getRankingInfo: if set to 1, the result hits will contain ranking
* information in _rankingInfo attribute.
* - aroundLatLng: search for entries around a given
* latitude/longitude (specified as two floats separated by a comma).
*   For example aroundLatLng=47.316669,5.016670).
*   You can specify the maximum distance in meters with the aroundRadius parameter (in meters)
*   and the precision for ranking with aroundPrecision
*   (for example if you set aroundPrecision=100, two objects that are distant of
*   less than 100m will be considered as identical for "geo" ranking parameter).
*   At indexing, you should specify geoloc of an object with the _geoloc attribute
*   (in the form {"_geoloc":{"lat":48.853409, "lng":2.348800}})
* - insideBoundingBox: search entries inside a given area defined by the two extreme points
* of a rectangle (defined by 4 floats: p1Lat,p1Lng,p2Lat,p2Lng).
*   For example insideBoundingBox=47.3165,4.9665,47.3424,5.0201).
*   At indexing, you should specify geoloc of an object with the _geoloc attribute
*   (in the form {"_geoloc":{"lat":48.853409, "lng":2.348800}})
* - numericFilters: a string that contains the list of numeric filters you want to
* apply separated by a comma.
*   The syntax of one filter is `attributeName` followed by `operand` followed by `value`.
*   Supported operands are `<`, `<=`, `=`, `>` and `>=`.
*   You can have multiple conditions on one attribute like for example numericFilters=price>100,price<1000.
*   You can also use an array (for example numericFilters: ["price>100","price<1000"]).
* - tagFilters: filter the query by a set of tags. You can AND tags by separating them by commas.
*   To OR tags, you must add parentheses. For example, tags=tag1,(tag2,tag3) means tag1 AND (tag2 OR tag3).
*   You can also use an array, for example tagFilters: ["tag1",["tag2","tag3"]]
*   means tag1 AND (tag2 OR tag3).
*   At indexing, tags should be added in the _tags** attribute
*   of objects (for example {"_tags":["tag1","tag2"]}).
* - facetFilters: filter the query by a list of facets.
*   Facets are separated by commas and each facet is encoded as `attributeName:value`.
*   For example: `facetFilters=category:Book,author:John%20Doe`.
*   You can also use an array (for example `["category:Book","author:John%20Doe"]`).
* - facets: List of object attributes that you want to use for faceting.
*   Comma separated list: `"category,author"` or array `['category','author']`
*   Only attributes that have been added in **attributesForFaceting** index setting
*   can be used in this parameter.
*   You can also use `*` to perform faceting on all attributes specified in **attributesForFaceting**.
* - queryType: select how the query words are interpreted, it can be one of the following value:
*    - prefixAll: all query words are interpreted as prefixes,
*    - prefixLast: only the last word is interpreted as a prefix (default behavior),
*    - prefixNone: no query word is interpreted as a prefix. This option is not recommended.
* - optionalWords: a string that contains the list of words that should
* be considered as optional when found in the query.
*   Comma separated and array are accepted.
* - distinct: If set to 1, enable the distinct feature (disabled by default)
* if the attributeForDistinct index setting is set.
*   This feature is similar to the SQL "distinct" keyword: when enabled
*   in a query with the distinct=1 parameter,
*   all hits containing a duplicate value for the attributeForDistinct attribute are removed from results.
*   For example, if the chosen attribute is show_name and several hits have
*   the same value for show_name, then only the best
*   one is kept and others are removed.
* - restrictSearchableAttributes: List of attributes you want to use for
* textual search (must be a subset of the attributesToIndex index setting)
* either comma separated or as an array
* @param callback the result callback called with two arguments:
*  error: null or Error('message'). If false, the content contains the error.
*  content: the server answer that contains the list of results.
