The introduction to Reactive Programming you've been missing

What I mean when I say "I think VR is bad news".
This just got linked to by the Y combinator news account, without proper context,
so a brief introduction: A month ago (end of May / early June 2014) I had a
Twitter conversation with a bunch of acquaintances. One tweet in the middle
of that thread, with obligatory hyperbole, was me saying that I think VR is
bad news.
Well, that part of the thread (but not the rest that provides context) recently
got retweeted, and then someone asked me if I could explain what I mean by that,
and because Twitter is a great platform for delivering 140 character slogans and
not so great for lengthy explanations, I wrote this. So, obligatory disclaimer:
// If the ES6 Promise is available, it uses that, else:
Rx.config.Promise = RSVP.Promise;
// To promise with success
Rx.Observable
.just(42)
.toPromise(/* Optional Promise ctor like RSVP.Promise */)
.then(
result => console.log('Result', result),
reason => console.log('Reason', reason));
(require '[clojure.core.async :as a])
(def xform (comp (map inc)
(filter even?)

(partition-by #(< (apply + %) 7))

What is an FRP application.

An FRP application has the following properties

  • Functional, pure, immutable.
  • Reactive, your application is a DAG, you react to "core" inputs and from new outputs.

Being an immutable DAG

If your application is an immutable DAG it has certain properties
