What (jQuery) means in the end of function?

Question

I have a function:

var waitingDialog = (function($){
.....
return{
}
})(jQuery);

Also could you explain what $ means in the function? Is it going to work without that?

It's an IIFE taking `jQuery` as a parameter, and that parameter will be called `$` in the scope of the IIFE. — Dave Newton, Mar 25 '15 at 13:23

It means that jQuery (if it exists) will be passed to the function. $ is merely the name that variable will take in the scope of the function.
