javascript - React useState does not update value - Stack Overflow

I am a bit confused as to why this ponent does not work as expected:

function Counter() {
  const [count, setCount] = useState(0);

  useEffect(() => {
    const id = setInterval(() => {
      setCount(count + 1); // This effect depends on the `count` state
    }, 1000);
    return () => clearInterval(id);
  }, []); //
