Just as a side comment, the reason languages/tools are fun to learn is because it's usually quite easy to do so. You say you know R, but the depth of packages available for R is insane, and most of it requires a level of math that few possess. I'd punt on learning a new language and instead master a new skill - up your stats knowledge, force yourself to learn how some algorithm works, whatever,.. these things are all infinitely reapplicable skills, whereas a pretty compiles-to-JS language or prettier-C-derivative generally aren't so much.
