function expression has undefined passed in an IIFE

Question

why would one have to pass undefined as an argument in the below referenced function

 var x = (function (window, undefined){
      function x(){
        this. result = 0;
      }
  })(window);

I think that is a bad idea taking *keyword* as parameter name. — Mritunjay, Aug 14 '14 at 06:08

To make sure undefined references undefined and nothing else.
