The Redux DevTools let us wire up our Redux app to a time-traveling debugger. This can help us debug, test, and review the state of our application in a simple history that can be "bookmarked" and scrubbed through. In this lesson, we wire up the Redux DevTools into our app, and walk through the different "monitors" and options available.
