The kneejerk comment from the JS hater you're responding to may not have been made with that distinction in mind, but a distinction exists.
It's very much a possibility that the JS hater uses Firefox. Firefox is implemented using an Emacs-like architecture. The Firefox codebase includes millions of lines of JS, and that's been the case since before the language was JITted. For Firefox 1.0, 2.5, and 2.0, I used to run it every day on an 800MHz PIII with 128 MB (later 192 MB, wow-wee!) of RAM. The JS in the Firefox codebase wasn't written in the NodeJS style, and if it had been, that would have made it a non-starter.
Kneejerk JS haters are tiring, but so is the complicitness of NodeJS advocates in conflating JS with the NodeJS ecosystem.
