BUG · Counter stops at 1
The counter renders 0, ticks once to 1, then freezes. Find the bug. Fix it.
// Counter.jsx — increments once, then stops. Why?
function Counter() {
const [count, setCount] = useState(0);
useEffect(() => {
const id = setInterval(() => {
setCount(count + 1); // ❌ stale closure
}, 1000);
return () => clearInterval(id);
}, []); // ❌ empty deps freeze count
return <span>{count}</span>;
