사용 시 참고사항

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

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