What is a React Hook?

A React Hook is a special function that lets you use state and other React features in functional components.

Can you give me an example of a React Hook?

Sure! The useState hook allows you to add state to your functional components. Here's a simple example:

import React, { useState } from 'react';

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

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>Click me</button>
    </div>
  );
}

What are the benefits of using React Hooks?

React Hooks allow for cleaner and more reusable code, enable state management in functional components, and simplify component logic.

Are there any rules I need to follow when using Hooks?

Yes, there are two main rules: only call hooks at the top level of your component and only call them from React functions.
