title: Closures and access to parent variables no longer on the execution stack
body: <p>New to closures and the inner workings of JS. I have a somewhat stable grasp of execution contexts and the associated objects within it. And while I know how to identify a closure and what it may yield, I don't quite see where the parent variables reside, once the parent function is popped from the stack. </p>
  
  <p>I'd assume they become properties of the closure's variable object? But you know where that leads.</p>
