title: Create JS Object Literal with Uninitialized Members
body: <p>In JavaScript, is there a way to create object literals with uninitialized instance variables? </p>
  
  <p>The purpose would be to allow for iterating through the members using a for-in loop to initialize them in parallel with other similar objects for the sake of generalized code. At the moment, I am simply having to stick temporary dummy values (including "undefined") in for the members, so I was wondering if there is a way to get around having to do that. </p>
