The core concepts of Redux are closely tied to a framework known as Flux. Both share the same concept of a one-way flow of data and a centralized store to reduce actions into the application’s next state.

To make use of the Redux package, it can be installed using the Node Package Manager (npm). Then, its methods can be imported.

Let’s start by installing the redux package and importing its createStore() method. In the next exercise you’ll learn how to use this method.
