Angular Interview Practice

The NgModule decorator is fundamental in Angular as it defines an Angular module, which is a cohesive block of code dedicated to an application domain, a workflow, or a closely related set of capabilities. When using the NgModule decorator, it allows developers to declare which components, directives, and pipes are part of the module, effectively bundling them together. Moreover, it specifies the services that the module provides and can also dictate dependency injection through its providers.

This modularity plays a significant role in structuring an application, making it easier to manage, test, and maintain. Since Angular applications are built as a collection of modules, each with its designated purpose, the NgModule decorator essentially establishes the boundaries of features and functionality within the application.

While enhancing performance, routing, and internationalization are important aspects of Angular applications, these tasks are not the primary role of the NgModule decorator itself. Instead, they may rely on additional Angular features, libraries, or practices to optimize or manage these areas.
