In this course, you will learn how to use React Hooks, which will help you achieve better code composition, code reuse, and unit testing ability as opposed to using class components.

You’ll start by reviewing what React Hooks are all about and why we need them. This will set the stage for the rest of the course. After that you will dive into the Hooks API, how to manage application state globally, as well as how to create custom hooks.

In the second half, you’ll get into unit testing and how to work with the popular useDependency Pattern. By the end of this course, you’ll have the confidence to write enterprise-level React Hooks code.
