What is what does redux mean?

Redux is a popular JavaScript library used for managing the state of an application. It is based on the Flux architecture, which is a pattern for building user interfaces that was developed by Facebook. Redux provides a predictable and centralized way of managing the application state, making it easier to reason about and test the code. It operates through a single-store system, an object that holds the global state of the application, and a set of actions that can be dispatched to modify that state. Redux is widely used in front-end frameworks such as React, Angular, and Vue.js.
