What is state in React and how do I use it?

State in React is an object that holds data that may change over the lifecycle of a component. You can use the useState hook to manage state in functional components.

Can you show me an example of using useState?

Sure! 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>
  );
}

This code creates a counter that increments when you click the button.

What happens if I don't use state?

If you don't use state, your component won't be able to manage or respond to changes in data. It will render static content, which means it won't update dynamically based on user interactions.
