So, this utility is fairly often needed for various reasons. Not providing it in nodejs itself means that people try to rewrite it, badly. (Or may I say, inefficiently.) (I'm obviously not trying to put the blame on someone there, except on node.js for not providing the functions ;-).)
This is part of the standard library in most other languages. Whether it's C, python, java, and surely others. I believe node.js would benefit its addition as well.
