Async/Await 101

For those who have never heard of this topic before, here’s a quick intro 

• Async/await is a new way to write asynchronous code. Previous alternatives for asynchronous code are callbacks and promises. 
• Async/await is actually just syntax sugar built on top of promises. It cannot be used with plain callbacks or node callbacks. 
• Async/await is, like promises, nonblocking. 
• Async/await makes asynchronous code look and behave a little more like synchronous code. This is where all its power lies.
