Which programming language is very popular in now??

Answer 1

That depends a lot on your environment. For example, Python in many sectors is currently popular (Machine Learning & AI) but as I am interested in web development I have seen JS gaining increasing popularity with its frameworks, new syntax and Node.js

Because of that I do not think it's possible to give you a really objective answer

Answer 2

Kotlin is going to be big. You should take a look at it
