Answer
React state does not synchronize with 60fps rendering. rAF ensures frame-perfect updates.
Quick Answer
React state updates are batched and processed asynchronously — not frame-synchronized. Animations updated via React state can miss frames and feel janky. requestAnimationFrame runs exactly once per frame, before the browser paints, synchronized with the display refresh rate. For smooth animations, update the DOM directly via requestAnimationFrame or use CSS transitions/animations.
