// Arrows
// A function shorthand that binds `this` value.
// Arrow functions are always anonymous.
//
// // Basic syntax:
// (param1, param2, paramN) => { statements }
// (param1, param2, paramN) => expression
// equivalent to: => { return expression; }
// Parentheses are optional when there's only one argument:

// Reference: http://www.html5rocks.com/en/tutorials/es6/promises/
// `Promises` have been introduced natively as a part of ES6 now. In this blogpost hopefully I will
// try to explore all the aspects of `Promises`.
// So what is a Promise?
// `Promises` are merely a prettier way of writing code which makes an asynchronous code look like synchronous.
// Usual way of XHR
