Your team is developing a React application with complex state logic that includes asynchronous operations. Which middleware for Redux can help manage these side effects?

When dealing with complex state logic and asynchronous operations in a Redux-based React application, Redux Saga is a middleware that can help manage these side effects effectively. Redux Thunk is another option for handling asynchronous actions in Redux, but Redux Saga offers more advanced capabilities for managing complex asynchronous flows, making it a better choice in this scenario. Redux DevTools Extension is a tool for debugging and monitoring, not for managing asynchronous operations, and Redux Router Middleware is used for routing-related tasks, not for handling asynchronous state updates.
