javascript - What is x.fn.x.init[] value shown for $() and $(this) in chrome dev tools -


i have habbit of debugging js , jquery script in developer tool. realized chrome dev tools showing x.fn.x.init value $() , $(this). dont realize these value:

code

<!doctype html>  <html lang="en" xmlns="http://www.w3.org/1999/xhtml"> <head> <meta charset="utf-8" /> <script src="jquery-2.0.2.min.js" ></script> <script src="jquery.ui.widget.js" ></script> <title></title> <script type="text/javascript">      $(document).ready(function () {         var outstring = "";         outstring = "" + $() + $(this);     });  </script> </head> <body> </body> </html>

enter image description here

this real code behind instantiating $

take @ github source 

jquery.fn = jquery.prototype = {     // current version of jquery being used     jquery: core_version,      constructor: jquery,     init: function( selector, context, rootjquery ) {         var match, elem;     .....

and @ line 263

// give init function jquery prototype later instantiation jquery.fn.init.prototype = jquery.fn;

since using minified version, gets turned see.
