2) Automatic Batching
- Batch multiple state updates automatically.
- Improve performance by reducing unnecessary renders.

3) New Hooks

4) Suspense
- Suspend rendering while waiting for async data.
- Create smoother loading states without manual loading indicators.

5) Benefits of Concurrency
- Improved User Experience: Prioritize user inputs for fluid interactions.
- Efficient Resource Utilization: Schedule work based on priority.
- Enhanced Performance: Handle complex UIs and workloads better.

6) How to Implement Concurrency
