what difference does it make? There are plenty of cli commands implemented in python/ruby/dtrace/shell and you're not aware of them. What's different about node aside from your negative bias?
There are no common tools in nodejs, no system ships with node. I only have node on my production servers, because Rails needs a JS engine and node is fast.
Actually i assume nearly every techie tries to avoid installing hundreds of different interpreters with even more dependencies just to run tiny scripts which could be replaced by a smart shell one liner.
I would immediately notice if I accidentally ran a Ruby or a Node.js script or a dtrace¹ script. That's because I don't have of these interpreters installed on my system.
