Async & Await in JavaScript.js

/* There is a special syntax to work with pronous in JavaScript. A function can be made async by using async keyword.
An async function always returns a promise, other values are wrapped in a promise automatically.

The await keyword makes javascript wait untill  the promise settles and returns its value. Its just a more elegant syntax of getting the promise result.*/
