Angular FAQ: Top Questions

Lifecycle hooks allow Angular to tap into key moments in a component’s lifecycle: creation, update, and destruction. Common hooks include:

• ngOnInit(): Runs once after component is initialized.
• ngOnChanges(): Called when input properties change.
• ngOnDestroy(): Cleanup logic when component is destroyed.

export class ExampleComponent implements OnInit, OnDestroy {
  ngOnInit() {
    console.log('Initialized');
  }

  ngOnDestroy() {
    console.log('Destroyed');
  }
}
