What programming language can be learned after java and kotlin?

Question

IT education

I am confident in the basics of java and kotlin, at the moment I am mastering android development. But I also want to learn a new programming language (preferably functional, because it's interesting to look at different tasks from the other side). It is desirable that the language be popular enough.

Answer 1

I'm confident in the basics

It is type if-else with cycles you are able to fence?
To begin with, just confidently master at least one language, until you can solve real problems, after that the question "what's next" should disappear by itself.
PS Initially, asking a question like "What programming language can I learn" is fundamentally wrong. You need to ask "which jap solves problem X better", but you don't have any problem, and accordingly you won't get a normal answer. So learn normally one language and do not do nonsense.

Answer 2

Scala?
