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

# Why do we need our own hooks? 

So far, you have seen the usage of official React hooks.  Hooks cover many common use cases for you to manage the state and the side effects in React components. However, do not stop there.

If an application needs the same stateful logic in two different places, it is a good idea to extract this code into your own hook. By doing so, you can share any stateful logic as a standalone module that can be tested on its own, shared, and  _reused_. 

Custom hooks can take any number of input arguments and return anything just to suit your needs. This is another awesome benefit to owning hooks. In addition, you are not limited to returning an object, an array of objects, or even another function.

Examine the need for building custom hooks and explore the guidelines for creating them.
