How does query invalidation work in React Query?
Query invalidation in React Query allows you to mark queries as stale, prompting them to refetch data when needed.

Sure! If you update a resource on the server, you would invalidate the query to ensure the client has the latest data.
How do I invalidate a query programmatically?
You can use the queryClient.invalidateQueries('queryKey') method to invalidate a specific query.
What happens if I don't invalidate a query after a mutation?
If you don't invalidate a query, the client may display stale data until the query is refetched.
