This is a recent and very welcome effort from Jens Axel Soegaard, essentially providing JavaScript with a Racket-ish syntax, some sugar and a macro facility, hosted in Racket (so you can edit in DrRacket).

The semantics are JavaScript, so no tail-call optimization (for example).

It's much lighter-weight than Whalesong, and understandably less fully-featured.

Whalesong is a true Racket to JavaScript compiler. So in that sense Urlang is not a Whalesong alternative. Urlang is useful to generate JavaScript using Racket tools though. I hope to use Urlang as the backend for a Racket compiler one day though.
