 # 9 - Redux
 
-In this chapter (which is the most difficult so far) we will be adding [Redux](http://redux.js.org/) to our application and will hook it up with React. Redux manages the state of your application. It is composed of a **store** which is a plain JavaScript object representing the state of your app, **actions** which are typically triggered by users, and **reducers** which can be seen as action handlers. Reducers affect your application state (the *store*), and when the application state is modified, things happen in your app. A good visual demonstration of Redux can be found <a href="http://slides.com/jenyaterpil/redux-from-twitter-hype-to-production#/9">here</a>.

 In order to demonstrate how to use Redux in the simplest possible way, our app will consist of a message and a button. The message says whether the dog has barked or not (it initially hasn't), and the button makes the dog bark, which should update the message.
