Angular 2 (Angular 4) – Observables and rxJS

In this video we look at Observables in Angular 2, and where the idea comes from. I speak briefly on Reactive programming and how data is perceived as streams, how the observable model in rxJS uses delayed execution using LINQ.

To read more on reactive programming see the following 2 links:-
