Why do you need Redux With React?
If performance is a concern, the best way to improve performance is to skip unnecessary re-renders, so that components only re-render when their data has actually changed. React Redux implements many performance optimizations internally , so that your own component only re-renders when it actually needs to.
What is Redux and why is it used?
What is Redux? Redux is a predictable state container designed to help you write JavaScript apps that behave consistently across client, server, and native environments and are easy to test. While it’s mostly used as a state management tool with React, you can use it with any other JavaScript framework or library.
What is Redux in simple words?
Redux follows the one-way data flow of React . To change the state we dispatch actions and reducers process the changes. All the reducers receive all the actions.
Is Redux useful anymore?
With all that said, Redux is still a great product . ... This is possible to handle in React as well, but the end result is still much easier to both share, reuse and reason about in Redux. A third use case is for those where the state of your application can change very rapidly.

Is Redux saga overkill?

Redux is most useful when in cases when:
You have large amounts of application state that are needed in many places in the app. The app state is updated frequently. The logic to update that state may be complex.
What problem does Redux solve?
