Beikut adalah contoh penggunakan UseState di React, untuk mempercantik tampilan saya akan menyertakan App.css
Program App.js
import "./App.css";
import { useState } from "react";
function App() {
const [count, setCount] = useState(0);
const handleIncrement = () => {
setCount((count) => count + 1);
};
const handleDecrement = () => {
setCount((count) => count - 1);
};
return (
<div>
<div className="hook">UseState</div>
<div className="App">
<div className="counter-row">
<button onClick={handleDecrement}>Decrement</button>
<div className="counter-value">{count}</div>
<button onClick={handleIncrement}>Increment</button>
</div>
</div>
</div>
);
}
export default App;
Program App.css
