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.

A Deep Dive into React Hooks

The following sequence diagram depicts data flow for a component using the `useDependency` pattern.

Here the `User` component can request and receive the prop as needed for rendering. Also, all of the functionality to retrieve data from the API is the responsibility of a custom hook. It makes it possible to reuse such code in other components too.

Explore the flow diagram and basic design for “useDependency” hook pattern.
