Use Case
This method can be used when you need to manipulate the DOM directly, often in scenarios where you are working with non-Angular libraries or need to integrate with existing DOM elements that are not part of Angular’s template system.

Pros
— Direct control over the DOM.
— Can be useful for integrating with non-Angular libraries or existing scripts that manipulate the DOM directly.

Cons
— Bypasses Angular’s change detection and lifecycle hooks.
— Can lead to issues with Angular’s dependency injection and component lifecycle management.
— Harder to maintain and debug.

Performance Impact
Potentially high impact due to bypassing Angular’s optimized change detection. Direct DOM manipulation can also lead to performance issues if not handled properly.

Places Where We Can Use Dynamic Module Loading

— Micro-Frontends: When integrating multiple micro-frontends, each built with different versions of Angular or other frameworks, dynamic module loading can help load and compile modules based on the frontend in use.

— Third-Party Integrations: If your application needs to integrate third-party Angular libraries or components dynamically at runtime, dynamic loading can optimize their performance and only include the necessary code.

— Role-Based Access Control (RBAC): Dynamic module loading is excellent for conditionally loading parts of the application based on the user’s role or permissions. You can securely avoid loading unnecessary modules for users with restricted access.
