ANGULAR INTERVIEW QUESTION: What is the '<router-outlet>' tag in Angular?

The RouterOutlet is a directive of the Angular router allowing you to dedicate a placeholder in your template.

Then, the Angular router displays the components related to the current route in this placeholder.

For example, if the URL is '/dashboard', the router outlet will display the 'DashboardComponent' where the  tag is located.

Ex of app.component.html
