Redux Toolkit is a package that simplifies the process of working with Redux by providing utility functions and abstractions that streamline common Redux patterns and best practices. It includes several features that enhance the development experience and make Redux code more concise and maintainable.

Key features of Redux Toolkit:

• configureStore: Redux Toolkit provides a configureStore the function that abstracts away the boilerplate code required to set up a Redux store. It simplifies store creation by combining several Redux middleware and enhancers commonly used in Redux applications, such as Redux DevTools Extension integration, middleware setup, and production optimizations.
• createSlice: The createSlice function allows developers to define Redux slice reducers more concisely and intuitively. It generates action creators and action types automatically based on the reducer functions provided, reducing the amount of repetitive code and boilerplate typically associated with Redux action creators and action types.
• Immutability Helpers: Redux Toolkit provides utility functions for working with immutable data structures, such as createReducer and createSelector. These functions simplify the process of updating nested state objects immutably within reducers and creating memoized selectors for efficient data retrieval.
• Redux DevTools Extension Integration: Redux Toolkit seamlessly integrates with the Redux DevTools Extension, enabling developers to visualize and debug Redux state changes in real-time during development. It automatically sets up the necessary middleware for DevTools Extension integration, making it easier to inspect and track changes to the Redux store.
• Thunks Middleware: Redux Toolkit includes the createAsyncThunk function, which simplifies the process of handling asynchronous logic in Redux using thunks. It generates thunk action creators that encapsulate async operations and dispatch Redux actions based on the async operation’s lifecycle (e.g., pending, fulfilled, rejected), making it easier to manage async state and side effects.
