All right, please allow me to start over:
QUESTION: If a lone pair of parentheses can be used to automatically
call a function, then what does it mean when two pairs are juxtaposed
in the same statement as follows: ()(jQuery);?
BACKGROUND: I have recently learned that any named or anonymous
JavaScript function can be made into a named jQuery method according
to the following reassignment
(function($) {$.fn.METHOD_NAME = function() {FUNCTION_CODE}})(jQuery);
A significant portion of this statement I can easily recognize as
JavaScript -- namely,
$.fn.METHOD_NAME = function() {FUNCTION_CODE};
where function() {FUNCTION_CODE} is an anonymous function assigned to
the object $.fn as a method named METHOD-NAME.
I can also understand the phrasing
function($) { }
where $ is some parameter assigned to an unnamed function. If I have
understood correctly $ is an alias for the jQuery object that is
passed to this unnamed function.
What I do not understand is the following unusual construction: ()
(jQuery);
If I remember correctly, a single, empty pair of parentheses can be
used at the end of a function statement to automatically load a
function. I believe the format is:
function( ) {
FUNCTION_CODE;
}
();
The construction ()(jQuery); is, however, none of what I recognize as
JavaScript. Can someone explain it?
