 * 동일한 루트에서 `render`를 두 번 이상 호출하면, React는 필요에 따라 DOM을 업데이트하여 사용자가 전달한 최신 JSX를 반영합니다. React는 이전에 렌더링 된 트리와 ["비교"](/learn/preserving-and-resetting-state)해서 재사용할 수 있는 부분과 다시 만들어야 하는 부분을 결정합니다. 동일한 루트에서 `render`를 다시 호출하는 것은 루트 컴포넌트에서 [`set` 함수](/reference/react/useState#setstate)를 호출하는 것과 비슷합니다. React는 불필요한 DOM 업데이트를 피합니다.
 
+* Although rendering is synchronous once it starts, `root.render(...)` is not. This means code after `root.render()` may run before any effects (`useLayoutEffect`, `useEffect`) of that specific render are fired. This is usually fine and rarely needs adjustment. In rare cases where effect timing matters, you can wrap `root.render(...)` in [`flushSync`](https://react.dev/reference/react-dom/client/flushSync) to ensure the initial render runs fully synchronously.
