React is a declarative component-driven UI architecture engineered by Meta. It utilizes state containers and a virtual browser DOM tree replica to compute modifications efficiently before making paint calls on the screen.
import React, { useState } from 'react';
function CounterButton() {
const [clicks, setClicks] = useState(0);
return (
<button onClick={() => setClicks(clicks + 1)}>
Total Interactions: {clicks}
</button>
);
}
