Question

Accepted Answer

Angular lifecycle consists of eight different phases.

The first phase is ngOnChanges() which is called when a component receives data-bound input properties.
The second phase is ngOnInit() which is called once the component is initialized.
The third phase is ngDoCheck() which is called during every change detection run.
The fourth phase is ngAfterContentInit() which is called after the component's content has been projected into its view.
The fifth phase is ngAfterContentChecked() which is called after every check of the component's content.
The sixth phase is ngAfterViewInit() which is called after the component's view has been initialized.
The seventh phase is ngAfterViewChecked() which is called after every check of the component's view.
The eighth and final phase is ngOnDestroy() which is called just before the component is destroyed.
