but "JS" implies it is some sort of amalgam of the J and S programming languages - or it doesn't and probably the Java implication doesn't exist anymore either - who really, on hearing the name in a modern context is going to think "hey, it must be a scripting version of that one really old programming language granddad in the office is always reminiscing about"?
sure they use it, but I sort of feel the groups that use it and JavaScript are no longer likely to cross over each other, and thus new devs will not be making the historical mistake of rhetorical misunderstanding that was made in the old days.
