Stuff like this is so difficult to test for yourself isn't it.

<!doctype html>
<html lang="en">
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>x.y.z</title>
    <script type="application/javascript">
      function gebi(x) { return document.getElementById(x); }
      var x = JSON.parse('{"y":{"z":"zed"}}');
      function stuff() {
        gebi("tofx").value = typeof( x );
        gebi("tofxy").value = typeof( x.y );
        gebi("tofxyz").value = typeof( x.y.z );
        gebi("strx").value = x.toString();
        gebi("strxy").value = x.y.toString();
        gebi("strxyz").value = x.y.z.toString();
      }
    </script>
  </head>
  <body onload="stuff();">
    <pre>
      var x = JSON.parse('{"y":{"z":"value"}}');
    </pre>
    <p>
      typeof x = <input id="tofx"><br>
      typeof x.y = <input id="tofxy"><br>
      typeof x.y.z = <input id="tofxyz"><br>
      x.toString() = <input id="strx"><br>
      x.y.toString() = <input id="strxy"><br>
      x.y.z.toString() = <input id="strxyz"><br>
    </p>
  </body>
</html>
