Are you aware of [Object.keys](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys)?

Thanks, yea I realize it exists but I really wrote the post to emphasize an interesting feature in JS:
for(anArray[counter++] in anObject)...

A few people already commented on my post saying that you can do this with Object.keys.  I am in no way saying you should use this over Object.keys.  In fact I updated the post to address the comments.  Sorry for the confusion.
