title: Can I use jQuery.extend to simulate method overloading?
body: <p>I'm quite familiar with jQuery. I'm trying to write common methods for my own purpose. Here is a sample below:</p>
  
  <pre><code>$.extend({
      add  : function(a, b)
             {
               return a + b;
             },
  
      add  : function(a, b, c)
             {
               return a + b + c;
             }
     });
  </code></pre>
  
  <p>Is the above scenario possible? Can I use the same extender name and pass different parameters, like method overloading?</p>
