# React 19 Concurrent Patterns

Keep what already works while you pick up React 19's newer APIs

## What this does

You are moving an app to React 19 and it already leans on concurrent features. This is about keeping those working while adopting what the new version adds. Reach for it during the migration, when you are deciding what stays as-is and what gets rewritten.

### Top 3 things it does for you

- Carry React 18 concurrent patterns through a version bump
- Work out where useTransition and useDeferredValue still belong
- Bring in newer APIs like use(), useOptimistic and Actions
