Add <router-outlet></router-outlet> in the template.?

Short answer: ✅

Example code

// app-routing.module.ts const routes: Routes = [ { path: 'home', component: HomeComponent }, { path: 'about', component: AboutComponent } ]; @NgModule({ imports: [RouterModule.forRoot(routes)], exports: [RouterModule] }) export class AppRoutingModule {} The RouterModule is a built-in Angular module that provides routing directives, services, and configuration to manage navigation between views. ✅ Imports in App: import { RouterModule } from '@angular/router'; You use it with RouterModule.forRoot() (for root module) or RouterModule.forChild() (for feature modules with lazy loading). Angular? Routes are defined as an array of objects using the Routes type, and each route object maps a path to a component. ✅ Example: const routes: Routes = [ { path: '', component: HomeComponent }, { path: 'products', component: ProductListComponent }, { path: 'products/:id', component: ProductDetailComponent }, { path: '**', component: NotFoundComponent } // wildcard route ]; Tools for Managing Routes: Route Guards Route Parameters Lazy Loading Query Params Nested Routes implemented? 🔸 Lazy Loading: Lazy loading is a technique to load feature modules only when needed, improving initial load performance. ✅ Implementation:

Real-world example (ShopNest)

ShopNest’s ProductListComponent binds *ngFor to products and uses (click) to add to cart.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
