Component Lifecycle

A component has a lifecycle managed by Angular itself. Angular manages creation, rendering, data-bound properties etc. It also offers hooks that allow us to respond to key lifecycle events.
Here is the complete lifecycle hook interface inventory:
ngOnChanges - called when an input binding value changes
ngOnInit - after the first ngOnChanges
ngDoCheck - after every run of change detection
ngAfterContentInit - after component content initialized
ngAfterContentChecked - after every check of component content
ngAfterViewInit - after component's view(s) are initialized
ngAfterViewChecked - after every check of a component's view(s)
ngOnDestroy - just before the component is destroyed
