      `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 ];

      ```
    
      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"));

        // code here never runs because there are rejected promises!

        // error.message === "2"

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

      example:

      let promise1 = new promise(function(resolve, reject){
        settimeout(function(){
          resolve('promise 1');

        // 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){

      }, 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
      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;
      });
      ```

    var promise$1 = function () {
        function promise(resolver) {

            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){

        }, 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
        });
        ```
