generate in ngOnInit(): void

-ngOnChanges -> called after a bound input property changes -ngOnInit -> called once the component is initialized -ngDoCheck -> called during every change detection run -ngAfterContentInit -> called after content (ng-content) has been projected into view -ngAfterContentChecked -> called every time the projected content has been checked -ngAfterViewChecked -> called every time the view ( and child views ) have been checked -ngOnDestroy -> called once the component is about to be destroyed

for @ViewChild and @ContentChild

The same change (add { static: true } as a second argument) needs to be applied to ALL usages of @ContentChild() if you use the selected element inside of ngOnInit (as we do it in the lectures).

If you DON'T use the selected element in ngOnInit, set static: false instead.

ex : @ContentChild('contentParagraph', {static: true}) paragraph: ElementRef; ex : @ViewChild('serverContentInput', {static: true}) serverContentInput: ElementRef;
