`std::min` isn't a library of its own, it's a function in the `<algorithms>` header of the Standard Template Library. The STL also encompasses a wide range of other things. There are some efforts to provide "the missing standard library" for JS, e.g. lodash.
Then the problem isn't that people don't know how to program, rather that js is missing standard functions. In the C++ world there is a large push to avoid rolling your own things, indeed even simple constructs like `for` loops are starting to be frowned upon.
