An example of an AI chatbot conversation about the useState hook in React.
What is the useState hook in React?
The useState hook is a function that allows you to add state to functional components in React.
Can you give me an example of how to use it?
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>
);
}
What does the setCount function do?
The setCount function updates the state variable 'count' to a new value, triggering a re-render of the component.
