Some of thr language features like operators can be overloaded using method tables, much like python's double underscore methods. I do think that the inability to do this in JS is what held it back from becoming a data processing powerhouse. But it perhaps can be made to run fast precisely because of the lack of such overrides (otherwise we'll be running python at JS speeds). That said, LuaJIT seems like a good compromise and might be best of both worlds.
