You will get an in-depth overview of how to handle asynchronous code with promises, generator functions, and the ES2017 async-await construct. These tools will help you set up communication with a server via an API later, when implementing a web application.

This powerful technique will not only allow you to write performant code, but it also makes it possible for you to handle infinite sequences.
