What are the lifecycle hooks in angular 10?

Answer»

LIFECYCLE hooks in angular are callback functions that angular calls when some events take place during the component's LIFE cycle. Let’s understand this concept with some examples-

  • ngOnDestroy- This lifecycle hook is called by the angular when a component is destroyed.
  • ngOnChanges- When a component’s INPUT property changes, angular invokes ngOnChanges.
  • ngOnInit- This lifecycle hook is called when a component is initialized for the FIRST time by angular.
