As long as you don’t care about unit test ability. Usually if you bothered to write them in Python or JS you usually don’t want to regress back to shell stuff. You’re already in a place where you have a runtime available so you can do way more stuff.

It’s usually the opposite direction that you mentioned that you want to go. You one liner some shell like awk to quickly get shit done without worrying about a runtime being available to you and then if you need it to be more robust and legible because of testing etc or production grade you move to a proper dynamic scripting environment
