From a theoretical perspective, lisp.

From a practical perspective, JavaScript.

Python for sure
Rust is peaking my interest though

Flutter is great for mobile and easy to get started - what we use for [Fountain](https://www.fountain.fm)

I code as a hobby and use python/flask, love it, simple and can focus on code.

It's *so* boring to program in though. I wrote the backend for https://grepmed.com in golang. tbf it runs like a top; it's just dreadfully verbose. It's basically C but with a great standard library, concurrency primitives, gc, and package management. Somehow, it's still not as fun to program in as C is.

Programming in Lisp expanded my programming mindset more than any language I've programmed in. The ability to basically create bespoke DSLs for everything just blew my mind. 

I like Go, because it teaches you different approach and mindset in comparison to JS, Java, c++...

Kotlin. I'm frequently looking for and missing many of it's super handy extension functions when working in other languages.

I formulate it mostly this way "i like project <x> and I want to contribute. For that reason I have to learn language <y>".
