A Deep Dive into React Hooks

React Hooks, introduced in React 16.8, revolutionized how we write components. They allow you to use state and other React features without writing a class. Let's explore some of the most common hooks. ### useState The `useState` hook is the most fundamental hook. It allows you to add state to functional components.

import React, { useState } from 'react';

function Counter() {
  const [count, setCount] = useState(0);

  return (
    

      
You clicked {count} times
       setCount(count + 1)}>
        Click me
      
    
  );
}

### useEffect The `useEffect` hook lets you perform side effects in functional components. It's a close replacement for `componentDidMount`, `componentDidUpdate`, and `componentWillUnmount`.

import React, { useState, useEffect } from 'react';

function Example() {
  const [count, setCount] = useState(0);

  useEffect(() => {
    document.title = `You clicked ${count} times`;
  }, [count]); // Only re-run the effect if count changes

  return (
    

      
You clicked {count} times
       setCount(count + 1)}>
        Click me
      
    
  );
}

By mastering these hooks, you can write cleaner, more concise, and more maintainable React applications.
