I can attest to this but it's definitely misleading. Some languages have features and patterns that are straightforward and easy to learn in that language, that once you've learnt you can emulate/replicate in almost every other language but only because you already know how it works, why it works and where the limits of your abstraction are.

And these abstractions will be often be overlooked or misused by developers who have not used them in languages where they're native; making them a net negative instead of an obvious benefit.
