Answer
React uses batched updates, event priority, offscreen rendering, browser input buffering, or hybrid refs for better performance.
Quick Answer
For large forms, avoid controlled inputs for fields that don't need real-time validation — use uncontrolled inputs (via refs) or form libraries like React Hook Form that minimize re-renders. Split the form into smaller components so only the changed field's component re-renders. Debounce expensive derived state computations.
