===== Object Extend =====
==== jQuery를 이용한 ====
<code javascript>
var bar = $.extend({}, foo);
</code>

==== Pure JavaScript ====
<code javascript>
function clone(obj) {
  if (obj === null || typeof(obj) !== 'object')
  return obj;

  var copy = obj.constructor();

  for (var attr in obj) {
    if (obj.hasOwnProperty(attr)) {
      copy[attr] = obj[attr];
    }
  }

  return copy;
}
</code>

<code javascript>
	console.log('bindingObject', bindingObject);
	for (var id in bindingObject) {
		console.log(id, bindingObject[id]);
	}
