I noticed that in the jQuery core, one of the two arguments passed in is undefined.
(function( window, undefined ) {
// Use the correct document accordingly with window argument (sandbox)
var document = window.document;
var jQuery = (function() {
// ...defintion of the rest of the core...
window.jQuery = window.$ = jQuery;
})(window);
Can anyone explain why the second argument is undefined?
Thanks in advance!
