Question

How want to call a webservice using http.get on Angular 2 handle the result and response to my caller with the result.

Is it better to use callback or promise ?

Thanks!! I use to work in NodeJS and often use callbacks.

Use `Observable.subscribe()` https://blog.thoughtram.io/angular/2016/01/06/taking-advantage-of-observables-in-angular2.html — Günter Zöchbauer, Jan 17 '17 at 09:00

In NodeJS we do a Callback but in Angular 2 it's better to use Promise or Observable.

Check this post to choose between Promise and Observable: Angular - Promise vs Observable
