Mastering Async/Await

by Valeri Karpov

Imagine writing your entire Express API or React app with for loops and if statements. No more deeply nested callbacks or convoluted promise chains. With async/await, you can make that dream a reality. Mastering Async/Await provides a concise and comprehensive guide to async/await fundamentals. You'll * Why React and Express don't support async/await out of the box, and how to work around these frameworks' limitations. * How to evaluate whether your favorite npm modules support async/await. * How promises work under the hood, in excruciating detail, by building a Promises/A+ compliant promise library from scratch. * Why async/await is the perfect complement to promises, rather than an alternative. * How to use async/await to handle errors and keep nasty red error messages out of your Chrome console. Mastering Async/Await packs all this and more into 52 terse pages. That means you can get caught up on modern asynchronous JavaScript in hours, not days. Instead of cobbling together copy/pasted snippets from StackOverflow, become the expert your team goes to for all things async.

If you do not understand the concept of asynchronous code I suggest you to read "Mastering Async/Await" . It will improve your understanding of promises and how they work under the hood. Do not rush through the book. Take your time and try to implement few examples on your own. It will help you to understand some edge cases.
