How does state work in React components?

How does state work in React components?

In React, state is an object that determines how that component renders and behaves. It can be updated using the setState function.

Can you give me an example of using state in a functional component?

Sure! In a functional component, you can use the useState hook. For 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 happens if I don't use state properly?

If you don't manage state properly, it can lead to unexpected behavior, such as components not re-rendering when they should or displaying stale data.
