In here I’m talking about Redux in React. I highly recommend, you should have proper knowledge about React fundamentals before going through this concept.

First we see what is the definition about the Redux. In React documentation has a proper definition for the Redux as fallows.

“Redux is a predictable state container for javaScript apps”

So to understand this I’ll break this as a three part as fallows.

 It is for JavaScript apps

 It is a state container

 It is predictable

Then let’s dive deeper in this three part

Redux for JavaScript application -> Redux…
