#redux

Explain the problem of state management in large frontend applications. What is "prop drilling"? How do libraries like Redux or Zustand solve this problem? Describe the basic concepts of a global store, actions, and reducers (or their equivalents).

Use Redux Toolkit for efficient Redux. APIs: 1. configureStore with defaults. 2. createSlice for reducers and actions. 3. Immer for immutable updates. 4. createAsyncThunk for async logic. 5. RTK Query for data fetching. 6. Entity adapter for normalized data. 7. TypeScript inference. 8. DevTools extension. No more action constants. Use createSelector for memoized selectors and implement listener middleware for side effects.
