Use JavaScript's Async/Await with Promises

If promises are like a yield sign, JavaScript’s await function modifier is a stop sign. To write asynchronous code in Node.js in a way that reads like synchronous code, we can use the async/await JavaScript keywords. Sometimes you want a logical flow to wait for something to complete without blocking the Node process, and only then move on to the next line. Async/await are relatively new features, available in Node.js v7.6 and up. The basic idea behind async/await is to write asynchronous code that looks and behaves similarly to synchronous code. Code that will be executed in the order it was written.

In this tutorial you'll learn:

  • What the JavaScript async/await function modifiers do
  • How to use async/await with Promises in Node
  • How to handle errors with async/await

By the end of this tutorial you'll have a better understanding of what the async/await keywords do and how to make use of them to manage the flow of asynchronous code.
