And that was it my friend! Today you’ve learned about the new async paradigm used in Angular 2, observables, and how it’s used by the new http module. You’ve also learned how to do error handling with Observables and how to take advantage of the async pipe to simplify your component’s code. Finally you discovered how you can still continue using promises if that’s what you like by taking advantage of the toPromise operator.
This article wraps up this introductory series to Angular 2. I really hope that you have enjoyed it! Expect more in-depth articles coming up in the near future :)
