React Hooks in Action: With Suspense and Concurrent Mode
useTransition is a React Hook that marks state updates as non-urgent transitions so urgent interactions can remain responsive.
- How it is used
- Improves perceived responsiveness when state changes trigger suspended UI, retaining usable content while new data or views load.
- How deep it goes
- Explains returned values, transition wrapping, pending feedback, and design-system integration, but does not detail scheduler internals.
- Examples
- Demonstrates user selection, suspended user details, opacity feedback, pending buttons, spinners, and the UsersPage implementation.
- What you can do after
- Apply useTransition to defer suspending updates, preserve interactive old UI, and communicate progress through isPending.

useTransition is a React Hook that marks state updates as non-urgent transitions so more urgent updates can be processed first.
- How it is used
- Keeps urgent interactions responsive while allowing heavier state-driven UI updates to trail behind.
- How deep it goes
- Defines low-priority updates and their user-experience rationale but defers detailed implementation.
- Examples
- Uses a spell-check button and delayed document error highlighting to illustrate priority trade-offs.
- What you can do after
- Evaluate when a UI update should be treated as non-urgent to preserve responsiveness.
