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.
