what is the difference b/w 

$(function(){

});

and 

(function ($) {
//found this code in jquery uobtrusive ajax
}(JQuery));

first code snippet is simply shorthand for document ready. i have no idea about second code snippet: what does it do and how does it differ from the first code snippet.

The second snippet creates an anonymous function and executes it immediately, without waiting for anything to load.

It's used to create a local variable (parameter) named $ that refers to jQuery, even if someone calls jQuery.noConflict().

It also hides internal variables created in the function from the global scope.
