React Router review

In this module we learned how to structure our app with React Router. We added components for Home, Missions, NewMission, individual Missions, and a 404 NotFound component.

We learned about Links, react router's useNavigate and useParams hooks, and dynamic routes. We managed some local state, added inputs, and introduced many styled components, including our own Button and Input.

In the next module we'll setup global state with Redux to allow our updates to persist.
