Summary
That's a lot of information! So let's recap.
First, we established that the primary job of the router is to manage navigation. And there are two ways to do it: imperatively, by calling router.navigate, or declaratively, by using the RouterLink directive. We learned about the difference between router.navigateByUrl and router.navigate: one takes the whole URL, and the other one takes a patch it applies to the current URL. Then we talked about absolute and relative navigation. Finally, we saw how to use [routerLink] and [routerLinkActive] to set up navigation in the template.
