Redux Toolkit

Redux Toolkit simplifies Redux with configureStore, createSlice (immer), and RTK Query for async, reducing boilerplate for predictable state.

Official, batteries-included.

Choose RTK when:

• Managing complex global state.
• Needing devtools/time-travel.
• Async thunks or queries.
• Large React apps.

Note: Use createAsyncThunk.

Persist with storage.
