useOptimistic for Instant Feedback
Show optimistic UI updates while a server mutation is in flight with useOptimistic.
Welcome
In this lesson you will use React 19's useOptimistic hook to show instant optimistic UI changes while a server mutation is in progress, with automatic rollback on failure.
What Is Optimistic UI?
Optimistic UI means assuming a server mutation will succeed and updating the UI immediately, without waiting for the server response. If it fails, you roll back to the previous state.
