How do I use useState in React?

You can use the useState hook to manage state in functional components. It returns an array with the current state and a function to update it.

Can you show me a simple example?

Sure! Here's a basic 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 creates a counter that increments when you click the button.

What if I want to set the initial state to a value?

You can pass the initial value as an argument to useState. For example, useState(10) will set the initial count to 10.
