Angular Interview Practice

A lazy-loaded module in Angular is defined by its ability to improve application performance by being loaded only when it is needed, rather than at the application's initial startup. This technique helps in reducing the initial load time, allowing users to access the essential parts of the application more quickly while loading additional features or modules as required. This on-demand loading is particularly useful in large applications with many components and routes since it helps manage resource usage efficiently.

When a lazy-loaded module is utilized, the Angular router can be configured to load specific modules only when the user navigates to a route associated with those modules. This defers the module's loading until the user actually needs it, which optimizes the performance of the application, especially for users who may not navigate through every part of the app.

The other options do not accurately describe lazy-loaded modules. For example, loading at the initial startup contradicts the essence of lazy loading, which intends to load modules only when necessary. Not every lazy-loaded module is completely independent, as some modules can have dependencies. Additionally, limiting functionality to HTTP requests does not capture the broad potential of lazy-loaded modules, which can encompass various features beyond just handling HTTP interactions.
