Understanding the Basics of React Hooks

Introduction

React Hooks have revolutionized the way we write functional components in React. In this post, we'll cover the basics of React Hooks and how you can start using them in your projects.

What are Hooks?

Hooks are special functions that allow you to "hook into" React features. For example, useState lets you add state to functional components.

Basic Hooks

1. useState: Manages state in a functional component.
2. useEffect: Performs side effects in functional components.
3. useContext: Accesses context in functional components.

Example

import React, { useState, useEffect } from 'react'
 
function Counter() {
  const [count, setCount] = useState(0)
 
  useEffect(() => {
    document.title = `You clicked ${count} times`
  }, [count])
 
  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>Click me</button>
    </div>
  )
}

Conclusion

React Hooks simplify state management and side effects in functional components, making your code cleaner and more readable.
