Answer 1

Here is a code example of what Gunter is talking about:

  constructor(private route: ActivatedRoute) { }

  ngOnInit() {
     this.route.params.subscribe(
     params => {
        let id= +params['id'];
        this.getProduct(id);
     });
  }

This code watches for changes to the parameters and executes any code inside the arrow function.
