Why isn't there LUA?

I think that LUA is a great language, and since codecademy helped my brother learn java, the first place I came was here. I was really surprised that they didn’t have it. I couldn’t really find another good place to learn, and I really hope they can add it in the future

There is poll somewhere, where you can vote for a new course. Codecademy can’t teach everything, there are too many language: swift, c#, c++, c, go(lang), R and so on

Here it is:
