Asynchronous Functions with async / await

Asynchronous functions added to the JavaScript specification in ES2016 with async and await can be seen as the next step in the asynchronous evolution of the JavaScript ecosystem. While still using promises under the hood, async/await makes them invisible and allows us to write asynchronous code that resembles synchronous code. No more callbacks,then(), or catch().

Note: Synchronous code is executed in sequence, meaning each statement waits for the previous statement to finish before executing. On the other hand, asynchronous code does not have to wait, meaning your program can continue to run.
