XState is a library that simplifies complex state management in React applications by treating application state as a finite state machine (FSM). It provides a clear, well-defined structure for managing states and transitions, making code simpler, predictable, and easier to maintain.
Redux Toolkit simplifies state management in React applications by providing tools and utilities for cleaner code, eliminating boilerplate code, and automatically managing state. It reduces the complexity of Redux setup and improves readability.
