title: How to determine if an object is an object literal in Javascript?
body: <p>Is there any way to determine in Javascript if an object was created using <a href="http://www.brainonfire.net/blog/javascript-object-literal-namespace/" rel="noreferrer">object-literal</a> notation or using a constructor method?</p>
  
  <p>It seems to me that you just access it's parent object, but if the object you are passing in doesn't have a reference to it's parent, I don't think you can tell this, can you?</p>
