React Hooks
Introduction to React Hooks
Welcome to the React Hooks course! In this course, you will learn how to use React Hooks to manage state and side effects in your functional components. React Hooks, introduced in version 16.8, allow you to write cleaner and more understandable components without the need for classes.
What are React Hooks?
React Hooks are functions that allow you to 'hook' into React state and lifecycle features from functional components. Before Hooks, only class components could have and manage state and access lifecycle methods.
Advantages of using Hooks
- Cleaner and more understandable code: Hooks allow you to split code based on what it does, not on lifecycle methods.
- No need for classes: You can use state and other React features without having to write a class.
- Logic reuse: You can reuse stateful logic without complex structures like render props or higher-order components (HOCs).
Prerequisites
To get the most out of this course, you should have a basic understanding of React and JavaScript. If you’ve ever created a stateful class component, you’ll have a good foundation to get started with Hooks.
Here’s a small example of what you can expect to learn:
javascript
In this example, the useState
Hook is used to add state to a functional component. You will see how, throughout the course, we use and explore this and other Hooks more deeply.

and useEffect
