React renders can freeze your user interface.
Heavy computations block the main thread. Your users see a frozen screen. This ruins the experience.
Interruptible rendering solves this. It lets React pause work to handle user input.
How it works:
- React splits work into small chunks.
- It checks for high priority tasks like clicks or typing.
- If a user interacts, React pauses the background task.
- React handles the input first.
- React resumes the background task later.
You use transitions to manage this. Use useTransition to mark non-urgent updates. This tells React to keep the UI responsive.
Stop letting heavy data processing kill your app performance.
