My understanding is that the latest development on Whalesong is dependent on a somewhat old version of Racket at this point. I believe a more up-to-date (but less complete?) effort is Racketscript: https://github.com/vishesh/racketscript https://github.com/vishesh/racketscript But, with Racketscript, I believe only a subset of the language is supported. IIRC, Clojurescript was able to make traction because they succeeded in mostly porting Clojurescript to Clojurescript. With the work to move Racket to Chez Scheme, they are writing more of Racket in Racket, so maybe that'll make Javascript an easier target? Of course, with Web Assembly, perhaps things will be even easier still.
