I was about to ask why you're using self from a variable instead of this, but apparently that's @gabrielecirulli's original code, which seems incredibly silly. Why make javascript something it's not?

(Though it was unnecessary in this case, maybe the better change on my part would have been to simply remove that variable.)

What variable?

Why are you replaced this with self?

@iirelu What are you talking about? What's wrong with the code?
