Ah I see. I wasn't saying it is the final answer. It's just a 'good thing' because without it I wouldn't have learned observables to the depth that I did.

It's a start... because it brings the concept to Javascript, a language that I'm already familiar with and have a build chain for.

If one is going to switch languages, then you can consider the whole sweep of compile-to-JS languages. Elm is pretty nice in that scenario, and pairs well with my use of Elixir on the backend.
