Answer
ChangeDetectorRef gives manual control over Angular’s change detection.
Used when working with OnPush, avoiding heavy re-renders, handling updates outside Angular zones, or running performance-sensitive operations.
Quick Answer
ChangeDetectorRef gives manual control over change detection. detach() removes a component from the CD tree (must manually call detectChanges()). markForCheck() marks an OnPush component to be checked on next CD cycle (useful when data changes externally). detectChanges() synchronously runs CD on this component and its children. Use when integrating non-Angular code that changes state without triggering Zone.js.
