I don't really like await . It seems to be a syntactical fix which acts in a quite magical way. Not sure if introducing magic to a language syntax is what we want. Rather, we should think about data flow of our async apps differently. I believe Observables are the future of async code. Once you grasp the concept that everything in your app can be transformed into streams of events, and you work with these events using chains of .map(), .filter(), .reduce(), etc. you'll grasp the true power of this paradigm and how well it fits async and/or concurrent apps. I suggest anybody that doesn't quite swallow the await syntax, to have a look at this presentation about Observables at Netflix as it's quite mind changing: [VIDEO]

Yes I meant what "Reactive Extensions" does. Should've been clearer that it was a reference to "functional reactive programming" and not a specific library. edit: "Async Javascript at Netflix" is a great talk on this - [VIDEO]
