Part 1: Understanding React Hooks

React hooks revolutionized how we write React components by allowing functional components to have state and side effects.

What are Hooks?

Hooks are functions that let you “hook into” React features. They allow you to use state and other React features without writing a class component.

Key Benefits

• › Simpler code structure - No need for class components
• › Better code reuse - Custom hooks enable logic sharing
• › Easier testing - Functional components are easier to test
• › Cleaner component lifecycle - Effects are grouped by concern, not lifecycle method

The useState Hook

The most basic hook is useState , which lets you add state to functional components:

 import { useState } from 'react';

function Counter() {
  const [count, setCount] = useState(0);
  
  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={() => setCount(count + 1)}>
        Increment
      </button>
    </div>
  );
} 

In the next part, we’ll explore the useEffect hook and side effects.
