Not at all.  Thats why I wrote "formatting code" in the commit and not "fixing code".  JS standard (as understood by my IDE) is not to have this trailing commas.  As I will be maintaining this code, I thought it was ok to change it so I stop getting warnings from the IDE.  If it is the same, having or not (despite the unrelated line change), I would prefer to have it this way.  Is this ok with you or should I revert changes?
