Angular Interview Practice

Which of the following best describes the purpose of an Angular module?

1. To define individual components

2. To facilitate routing within an application

3. To group related components, directives, and services

4. To manage the application stylesheet

The correct answer is: To group related components, directives, and services

An Angular module serves to group related components, directives, and services into cohesive blocks of functionality. This organization enables better code management, helps in encapsulating related features, and promotes modular design in Angular applications. By grouping these entities, modules make it easier to maintain and understand the application as it scales. Each module can import other modules, export its own components, directives, and services, and can even be lazy-loaded for improved performance, thus enhancing the application's scalability and maintainability. The other options focus on specific functionalities. While individual components are indeed defined within a module, that is just one aspect of a module's purpose. Routing is an essential feature in Angular applications, but routing is facilitated through specific Angular modules, like the RouterModule, not the purpose of a module overall. Managing the application stylesheet is also not a core purpose of Angular modules; styles are typically handled separately via stylesheets or component styles.
