Unless you're suggesting that NASA rewrite its rocket guidance subroutines in a brand-new interpreted language or something, it's probably not unequivocally "dangerous." (In that case, I would call the suggester a different word than "loser".) That's the whole point of open-source software: everyone can make their own judgments about what works better for them.

In the specific case of `replace`, if I want to know exactly what the command-line options do, exactly what order the files are being modified in, I can glance over 173 lines of javascript rather than search through the 4.3MB (uncompressed) of the sed source code. Sure, I suppose I'd have to include the Node.js source code to make it a fair comparison, but my point remains: choose the solution that makes the most sense to you.
