If you have to stick with 1 programming language forever for everything that you write... What would it be?
Ps: also remember about what language your career needs, your personal favorites... too
And apparently Python and JS are the most popular choices
@Ntechh some things like sockets and libraries are difficult in C++, and they are big compromises because of the language's age. Also the syntax, even in C++17, is mostly dated. There are alternatives popping right now like Rust that have similar performance and all that fixed. I'd recommend you to just check it out, just to know it is there. I don't use it but its ideas are interesting.
