  };
  
  var privateMethod = function () {
    // Do something private
  };
  
  $(document).ready( function () {
    // Do whatever you want and use jQuery as you usually would here,
    // e.g.
    SampleNamespace.publicMethod();
  });
  
}(jQuery, window.SampleNamespace = window.SampleNamespace || {}));
