> As for "pure" languages? Yikes, no language is perfect nor superior to all others, not even Rust. When they say "pure", they mean functional (no side effects, no mutations etc). They aren't meaning "pure" as in some kind of judgement... i.e. a "pure function" is a function that always returns the same output for the same input and has no side effects (it's essentially just a map from input->output). https://en.wikipedia.org/wiki/List_of_programming_languages_by_type#Pure https://en.wikipedia.org/wiki/List_of_programming_languages_...
