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

This lesson taught you how to use React Hooks to manage dependencies for React components. By doing so, you can:

- Share common logic
- Reduce code repetition
- Have better code composition
- Make unit testing easier

It is suggested to explore this idea further by adding more options to the configuration. You can use this pattern with Redux or any other state management solution that you may be using.

Once you use this pattern in multiple features, you should see a noticeable reduction in the boilerplate or repetitive code.

You may also explore the managing transition states with this pattern. For example, a common fetch request results in the following three states:

- Setting `isLoading` to `true`
- Dispatch response and setting `isLoading` to `false`
- Or dispatch error and setting `isLoading` to `false`



Read the final remarks on the benefits of using the “useDependency” pattern.
