Why does jQuery send in window to itself when it can just call it from within

I tried this myself and I suppose its some sort of closure catch but I dont see the difference in this: 

(function() {
 var tvLib = {}
 window.tvLib = tvLib
})();

from the jQuery way of : 

(function(window, undefined) {
var jq;
window.jq = jq;
})(window);

Im confused why I need to send in window object if I can call it anyway.

Solution

  • One reason is to let minifiers rename the variable to make it more compact.
