import { useState, useEffect } from 'react';
export default function AutoSaveCounter() {
const [count, setCount] = useState(0);
useEffect(() => { localStorage.setItem('count', count.toString()); }, [count]);
return (
<div>
<h2>Counter: {count}</h2>
<button onClick={() => setCount(count + 1)}>+</button>
<button onClick={() => setCount(count - 1)}>-</button>
<button onClick={() => setCount(0)}>Reset</button>
</div>
