well, it's a tough question but the answer is whatever you like, but if you are a complete beginner then i suggest to learn javascript first, to learn what programming actualy is and what type of programming language you need for you vision.
I'm not a fan of javascript, i don't even use it but for learning it's good.
Javascript is easy to learn, lots of tutorials, docs and much more features and it's also have some programming things which is also used by other languages for example list, loops.
Shifting to other language is lot more easy just few keywork will be changed.
