Introduction

React Hooks, introduced in React 16.8, have transformed the way developers manage state and side effects in functional components. This blog post explores the benefits and usage of React Hooks, unlocking new possibilities for building dynamic and scalable React applications.

Understanding React Hooks

React Hooks are functions that enable the use of state and lifecycle features in functional components. They provide a way to reuse stateful logic across different components, allowing developers to write more modular and readable code.

useState Hook

The useState Hook is used to add state to functional components. It returns an array with two elements: the current state value and a function that lets you update it.

// Example of using useState Hook
import React, { useState } from 'react';

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

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={() => setCount(count + 1)}>Increment</button>
    </div>
  );
};
