Defining Links Between Routes
RouterLink
Links to routes can be added using the RouterLink directive, which is part of ROUTER_DIRECTIVES along with RouterOutlet.
For example the following code defines a link to the route at path component-one.
<a [routerLink]="['/component-one']">Component One</a>
Navigating Programmatically
Routes can be navigated to by calling the navigate function on the router as well:
this.router.navigate(['/component-one']);
