Languages to learn in 2019

since you mentioned regex there, why not do it all?
Learn regex then context free language then context sensitive language and finally recursively enumerable language

You might just want to learn the CFG for the sake of understanding compilers and interpreters

You think people will go back to using ye olde c++?

i have a wired feeling that spanish is going to be the next industry standard

C++ is getting more features every day. Nobody should use a different language.

ARM assembly language

Why should you learn many languages? Just learn Java, its like a lingua franca.

I heard C# is much better language.

>Learn regex then context free language then context sensitive language and finally recursively enumerable language
What's an example of it?

The ONLY reason it isn't is Microsoft.

Prove me wrong.

I can't
There is a high probability that you're correct.
