Often languages like Javascript and Python don't allow optimal runtime complexity, because the types baked in to external interfaces fundamentally disallow the desired operation. And these languages are too slow to rewrite the core logic in the language itself. (but of course, the vast majority of the code, even in widely used tools, isn't properly designed for optimization in the first place) I only dabble in javascript, but `tsc` is abominable.
