Hi Mike,
You are right, I meant to say "enclosures of either kind"... ;-)
We are on the same page with this. You don't *have* to do with unless
noConflict() is on, but it's "safer" to do it anyway, specially when you
share your code (ie.: plugin developers). But like yourself, I do it all the
time to avoid accidentally messing around with global vars. It's "good
practice"...
Anyway, I'm glad to meet the guy who started it all :-)
I've actually ellaborated on the idea and come up with my own version:
;if(jQuery) (function($){
...
})(jQuery);
...which:
- encloses local vars
- silently ignores the code if jQuery is unavailable
- avoid colisions when files are merged (; at the start)
Cheers,
Diego A.
