Well, the title says the most. Just searching for a new one to learn. Mine is in fact, Python 3.7. I like Python 3.7, because it runs on like everything, even on my small raspi zero.
Mh I should add that I, in this moment, I speak Python, R, in advanced 8/10 levels of skill, HTML in beginner level, as I do in CSS and C++. JS in mid levels of skill
I'd naturally recommend js. Why?
1. It is widely used in both backend and front end web development.
2. Using packages like
electron you can make desktop apps. (Like discord, GitHub and repl.it desktop apps which of course you know about).
3. You can also make both native and hybrid mobile apps using js.
4. There are literally packages for everything in node.js, so nothing is very difficult even if you're just a beginner.
5. After you learn it, you might even find out some personal pros of the language.
There are quite a few cons too but I don't think I need to list them here.
