Cross Pollination: What have you learned from one language and applied to another?

For me, Rust made me think about using types for more correct code. In Python, I’ve started making classes for semantic values instead of using strings. Combined with a good IDE or a static checker like mypy ive caught several bugs that would have gone untouched.

From Object Pascal/Delphi I learned the value of OOP.
From Java I learned to dislike verbosity.
From Python I learned the true meaning of general purposeness and to use a multi paradigm language (funnily enough the more I use Python the less my code is object oriented).
From Ruby I learned to dislike magic but to appreciate it when it works.
From Erlang I learned to dream of infinitely scalable architectures that are resilient and fault tolerant and the value of a language that has concurrency built in from day one instead of being patched on like most general purpose languages.
From Go I learned how quite a "simple" language design can take over like wildfire. Simple ideas, albeit imperfect, can work.
From JavaScript I don't know if I learned anything :D. Maybe that people underestimate the complexity of async programming? The community around it is definitely more interesting than the language itself in my opinion.

As of today the languages I use most are still Python and Ruby and I've definitely carried on with me things I learned in other languages.

For me, it was being able to take everything I learned about C# and apply when making a node.js backend with typescript. But to be specific, generics and what an anonymous function is!
