Angular Interview Practice Exam 2025 - Free Angular Practice Questions and Study Guide

Angular modules play a crucial role in organizing and encapsulating related code components. They serve as a foundational structure within an Angular application, allowing developers to bundle related functionalities, components, directives, and services together. This modular approach facilitates better maintainability, scalability, and reusability of the code. By grouping related code, it becomes easier to manage dependencies and ensure that components that work together remain closely associated.

For instance, a feature module could contain all the components, services, and other dependencies needed for a specific feature of the application. This logical separation enables more efficient development processes, aids in lazy loading modules, and supports the overall architecture of complex applications.

The other options do not accurately reflect the primary purpose of Angular modules. Grouping unrelated code or managing only service files doesn't capture the essence of what modules are designed to accomplish. Additionally, handling global variables is not a specific function of Angular modules, as it is oriented towards encapsulation and organization rather than global state management.
