This. But also "Javascript" is a way overloaded term. The JS community is quite fragmented. Same could really be said of all of them. "Just use those" may come with a caveat of "also be conservative about what tooling you adopt around the language you choose."

I almost left Javascript off the list because of it's peculiar (but interesting!), prismatic nature. Still, they all transpile to Javascript (I think?), so really it's all just javascript ;)

In that case Nim should make the cut since it transpiles to C, C++, Obj-C, and JavaScript. :)
