A intro to RxJS and Observables as well as Angular 2 integration. At the time of this video Angular 2 was at Beta 6. The example code can be found at this repo https://github.com/splintercode/observable-rxjs-demos
One note there is a error I made early in the video at 1:50. I forget to resolve the promise and the console log the value given. I correct it at 4:50 later in the video.
