How does Angular handle heavy asynchronous UI operations?

Mid Angular
Quick Answer Handle heavy async UI operations: use trackBy in *ngFor to minimize DOM re-creation, virtual scrolling (cdk-virtual-scroll-viewport) for long lists, debounce user inputs before processing, run heavy computation in Web Workers (off main thread), use OnPush CD to minimize checks, paginate data instead of loading everything, and use requestAnimationFrame for animation-related work.

Answer

Uses zone.js, task queues, microtasks, and triggers change detection after async tasks complete.
