It was designed to be used with React, but it can also be used with other JavaScript frameworks and libraries.

Redux helps you manage the state of your application in a predictable and consistent way.

In Redux, the state of the entire application is stored in a single, immutable "store".

To change the state of the application, you need to dispatch an "action" to the store. An action is a plain JavaScript object that describes a change to the state.

The store processes the action and updates the state of the application based on a set of "reducers" that you define. A reducer is a pure function that takes the current state and an action as input, and returns the new state.

To access the state of the application, you can use "selectors", which are pure functions that take the state and return specific pieces of data.

Redux provides several benefits, including a clear separation of concerns, easy debugging, and better support for server-side rendering and offline apps.
