I program Java and javascript for money and a mix of APL, BQN, J, emacs lisp, and clojure for fun.

The biggest challenge is switching from one array language to another, they are very similar but have subtle differences that I forget. Mostly because I am still not proficient at any of them.

Switching between a mainly imperative OOP langauge to a functional language is always very smooth, especially since my preference is lisp so the syntax and patterns are completely different, although modern Java has taken on a lot of functional goodness.

But I never really think about the switch, it has all become second nature to me.

I never thought about it but maybe it is related to being multi-lingual? E.g. I can switch between Danish and English no problem as well.
