JavaScript for Line of Business Applications

I think things can be simplified to a single abstraction since the underlying problem to all of this is the same. I present to you CSP and the concept of channels. CSP has been highly influential in Go and recently Clojure embraced it as well with core.async. There's even a C version. It's safe to say that it's becoming quite popular (and validated) and I think we need to try it out in JavaScript. I'm not going to spend time comparing it with every other solution (promises, FRP) because it would take too long and only incite remarks about how I wasn't using it right. I hope my examples do a good enough job convincing you themselves.
