Please, let’s not get into language wars here. Everyone has their preference (I’m actually more of a Perl person).
JavaScript is as much a first class citizen of MacOS automation as AppleScript and others. Or as much third class as others, given Apple’s attitude to automation.
So if someone is having trouble with it, they deserve the same help as someone struggling with another problem. I think.
Slightly off-topic: JS is available across platforms. AppleScript is Mac-only. That, at least, is not a matter of taste
