Summary

React Router gives us a comprehensive set of components for managing the navigation between pages in our app. We learned that the top-level component is Router, which looks for Route components beneath it where we define what components should be rendered for certain paths.

So, NavLink is perfect for the main navigation element in an app and Link is great for other links that appear on pages.

RouteComponentProps is a type that gives us access to route parameters and query parameters. We discovered that React Router doesn't parse query parameters for us, but can use the native JavaScript URLSearchParams interface to do this for us.
