In the past, every keystroke in a search box would trigger heavy filtering immediately, leading to:
- Laggy input
- High resource usage
- Frustrating delays for users
Now with useTransition + useDeferredValue, React lets us:
- Keep typing snappy (urgent updates are instant)
- Run expensive filtering in the background
- Scale better with large lists
- Deliver fluid, responsive user experiences
This small shift in how we handle state updates is a game-changer for building modern, data-heavy apps.
