C++ != std::
C++ core langugage is one “thing”. C++ standard library is another “thing”. They are two different “things”. I do not like or use C++ std lib. There are more than few people, who feel strongly in favour of not using std lib, just the core C++ language. Please keep them distinct. std::vector, std::string
or
std::array
are not C++, they are C++ std:: lib abstractions.
Beyond C++ i do use standard C, C# for work. And yes I was perhaps some kind of Java Script SME. As it is perhaps evident on this site entries from arround 2019.
Thinking about language, focus on a language not its std lib
Truth is always simple.
