  const [count1, setCount1] = useState(0);


  const handleAsyncUpdate = async () => {
    setCount1(count1 + 2);
    setCount1(count1 + 1);
  };

  const handleSyncUpdate = () => {
    setCount1(count1 + 2);
    setCount1(count1 + 1);
  };

  console.log("render", count1);
  return (
    <div className="App">
      <h2>{count1}</h2>
      <button type="button" onClick={handleAsyncUpdate}>
        Click for async update
      </button>
      <button type="button" onClick={handleSyncUpdate}>
        Click for sync update
      </button>
    </div>
