The "simple promises" from JS are (somewhat crippled) copies of Futures from other languages. In Scala the results of those futures can be produced at the same time, even if they are purely computational as Scala and…
So their docs seem pretty clear that their lambda engine runs jvm based languages. Or at least java and scala, but if you can run java you can run scala and clojure and jruby etc.
