Introduction to Redux

Answer»

Developed by Dan Abramov and Andrew Clark in the year 2015, REDUX is nothing but an open-source library MADE using the scripting language JavaScript. Redux's primary use lies in managing and centralizing application states and it is USUALLY used along with JavaScript libraries, for instance, React or Angular to build UIs (User Interfaces). 

Redux's ARCHITECTURE is somewhat inspired by the architecture of Flux by Meta (or Facebook).  Redux can help developers develop applications that behave consistently, run in different environments (client, server, and native), and are easy to test. Redux can help the developers to centralize their application's STATE and logic. Because of this, a variety of amazing capabilities, for instance, Undo and Redo, state persistence, etc. are unlocked by Redux. Redux also provides a large number of add ons and can work with all sorts of User Interfaces. The Dev Tools provided by Redux also help us debug our applications.
