Problem Statement
What is RTK Query?
Explanation
RTK Query is a powerful data fetching and caching tool included in Redux Toolkit that simplifies loading data in web applications by providing automatic caching, request deduplication, and UI state management. It eliminates the need to write thunks and reducers for data fetching by hand, handles loading states automatically, and provides cache invalidation and optimistic updates. RTK Query works with any async data source including REST APIs, GraphQL, or any function that returns a promise.
