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

# Managing state with React Hooks



The following example demonstrates managing state with React Hooks using `useState` hook.

The `useState` hook is an alternative to using `this.state` or `this.setState` in class components. 

The `useState` hook returns the current value of the state and a function to update the state. 

Run the application to see it in action.

Build a counter application with React Hooks to increment the current count value on the click of a button.
