Short answer: Angular modules (NgModules) are containers that group related components, directives, pipes, and services. Purpose: Organize code Enable lazy loading Manage dependencies

Example code

@NgModule({ declarations: [LoginComponent], imports: [CommonModule, FormsModule], exports: [LoginComponent] }) export class AuthModule {} Real-Time Example: AuthModule for login and registration AdminModule for dashboard, user management

Real-world example (ShopNest)

ShopNest admin can be built in Angular with modules/components, services for API calls, and reactive forms for product edit.

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.
