¿ Which programming language is a must to know, nowadays?

JavaScript! ^_^

Java* obviously *_*

Javascript, Java, C++

Programming Languages Popularities might change over years, I'd prefer C++, Java, JavaScript, Python, or Ruby but watch out when these languages take over the top 10 languages: -Go -Rust -SCALA -Elixir -Erlang -Lua

Game Development: -C++ -Java -Lua -Swift etc. Web Development: HTML CSS JavaScript PHP SQL

I learned first html. I is the fountation of JavaScript and CSS too.

It honestly depends on which aspect of programming you want to base yourself on...

a c-based one (C#/CPP)
