Writing neat asynchronous Node JS code with Promises & Async/Await

Async functions return a Promise. If the function throws an error, the Promise will be rejected. If the function returns a value, the Promise will be resolved.

Await

Async functions can make use of the await expression. This will pause the async function and wait for the Promise to resolve prior to moving on.
