ngDoCheck() in Angular

In CustomerInfo Component you need to implement class with ngOnchanges than you can see changes made from the component.

in order to use life cycle hooks, we must implement that hook in with the class(Eg: export class TestClass implements OnDoCheck {} ) right?. But it is not there in the code ?

very clear example !!
