    interface OnDestroy {}

ngOnDestroy

Usage Notes

The following snippet shows how a component can implement this interface to define its own custom clean-up method.

          @Component({        selector: 'my-cmp',        template: `...`,        standalone: false,      })      class MyComponent implements OnDestroy {        ngOnDestroy() {          // ...        }      }
