What language to learn after PHP?

Question

Perl

At the moment I know PHP, HTML + CSS and JS at the level of jQuery scripts.
I work as a freelancer - I usually make online stores and landing pages.
As a student, like many, I dabbled with Delphi / Sibilder / Visual Basic 6.0, but my hands did not reach anything serious like Seasharp or Java.
Now there is a desire to learn something else, I'm looking towards Python, Perl, Java, C sharp. I would like to hear which of these languages ​​is most in demand, and in what areas it is used. What do you recommend to learn?
Update:
Chose python. I downloaded the tutorial https://pythonworld.ru/uploads/pythonworldru.pdf and a bunch of articles))

Answer 1

Ivan, you have the wrong question.
Firstly, it is not the knowledge of the language that is valued, but experience.
Secondly, I have a subjective impression that you do not know what you want.
If you want to be a sought-after specialist, look at the trends. Now it is data analysis, DL, machine learning. The language stack is basically Python.
If you want to develop games - C++/C, Java
Mobile development: Swift, ObjectiveC, etc.
Web development: Node.JS, Ruby, PHP
From (subjectively for me) exotic - Erlang, Rust.

Answer 2

I would personally look towards Python or Java. I'm leaning more towards Python. But this is IMHO.
