Enhanced promises

promisesEnhancedUsage.js

// This will return a promise of an Array
var promisedArray = $q.when([1,2,3]);

//Normal way of getting length in angular
promisedArray.then(function(arr) {
  var length = arr.length;
  // Do something with length in callback
})

//Using promises transformation
// This is a promise of a number
var lengthPromise = promisedArray.get('length');

//Calling methods
var biggerArrayPromise = promisedArray.call("push", {name: "Gonto"});
