To use React Suspense with an async localStorage API:

1. Create a Cache: Store data fetched from localStorage to avoid re-fetching.
2. Async Data Fetching: Use Suspense to handle async operations when fetching from localStorage.
3. Suspend on Data Fetch: Throw a Promise to trigger Suspense and display a fallback while loading. For detailed information, check the doc
