React Hooks revolutionized the way we write React components, allowing developers to use state and other React features without writing class components. This comprehensive guide will walk you through everything you need to know about React Hooks.

Understanding useState and useEffect

The useState hook is the most fundamental hook in React. It allows you to add state to functional components, making them more powerful and flexible than ever before.

"React Hooks don't replace your knowledge of React concepts. Instead, Hooks provide a more direct API to the React concepts you already know."

The useEffect hook lets you perform side effects in function components. It serves the same purpose as componentDidMount, componentDidUpdate, and componentWillUnmount in React classes, but unified into a single API.

• useState allows you to add state to functional components
• useEffect handles side effects and lifecycle methods
• Custom hooks enable code reuse across components
• Hooks make your code more readable and maintainable
