Let's review our app shell

At this point, we've got a basic app container in place. We've got a home page, a NavBar that changes theme (fancy), a Missions page that is set up to input some data, and that's about it.

Our app doesn't render any data, nor does it save the data that we do have. While we aren't going to save the data in this module (that's for the next module when we implement Redux), we will render some mock Missions in the page, build a table, and finish off the React Router features. We'll have the mock data route to its dynamic route on table click. And, when we reload the page on a specific Mission route, we'll useParams to learn what route we're on to render the appropriate data.

The rest of this module will set us up to easily start implementing Redux global state management in the next module, so hang tight.
