Yeah, I understand why, particularly when old IE browsers don't allow a comma trailing the final declaration. I just find it ugly as hell.



Unfortunately trailing commas still break IE7, which I wouldn't yet classify as old enough to ignore.


I'm not ignoring it but my code always runs through JSLint each time its saved and that picks up misplaced commas for me. Also we're not talking about client-side javascript here; fortunately Node.js uses the V8 Javascript engine, not the IE7 one. :)
