    Instructor: Now, instead of directly loading the person, let's click and then load it. The way that we do that is by, instead of mapping, we do what's called a switch map, and the switch map takes a function and returns an observable. I'm going to return the observable of people.

    Instead of calling this random, let's call it something like Luke, because that's who it's going to load. We'll put in Luke here, and make sure that Luke shows up here. Now, when I click on this button, you'll see that Luke loads in. If I change this to a two, it won't load Luke anymore.

    Instead, when I click, it'll load C-3PO. But we'll go ahead and keep that one for now. I'll click and load in Luke.
