View gist:bda667b09c0c4b7f9ee8
"use strict";

* It allows in many situations to avoid promise related boilerplate like
* factory('$loggedUser',['$login','$loadedConfig',function($login,$loadedConfig){
* return $login.then(function($login){

ForkJoinPool fjPool = []

// We are in AsyncTaskWithArg<Integer,Integer>
// function which take Integer param and calculate Integer
// both types are type inferenced
// method map will fork copy of the task for each element of given Iterable ( 2..<15 Range in this case)
// and when all results ready will merge them in to List<Integer>
// The task itself (the one applied to each element) uses fork/join (which is stupid for Fibonacci)
