Javascript

How about it? :-)

E.g. based on https://github.com/espruino/Espruino .

There's nothing that prevents anyone from starting a port, apart from maybe licensing, at least on the technical side of things. However some practical questions remain, such as the utility of such a port. I fail to see any practical uses of a JS interpreter. Also, the question of finding someone willing to do it remains. You would either have to find and convince a developer to do it for you, or do it yourself.

Allowing Rockbox programs to be written in a well-known language more powerful than those currently available.

Yeah, I figured that :-)

There is already a perfectly good lua port. If you want to write a plugin, it'd be much easier to just do it in C or lua than to port a whole JS interpreter. Also, most plugins are already written in C, which I'd classify as a well-known and powerful language.

Oh, yes I know that. But if RB had JS, then I wouldn't need to port the JS interpreter! I'd just dive right in and program in JS.

I said "more powerful than those currently available". C is one of the most primitive languages still in general use. JS's additional power includes object orientation, dynamic memory allocation, local functions, closures, pattern matching etc.

and lots of overhead for those features

Indeed. Lots to keep CPU and memory employed
