Why?

Use void 0

You are right, void 0 is probably the best way to do it as I just checked at http://jsperf.com/type-of-undefined-vs-undefined/6

I didn't put much thought into that. I guess there are better optimizations to be made in the code :)

i will update it next time I touch the code.

Also, big thanks for your article about Object.observe! Lack of it gives me headaches while working on my other project, https://github.com/warpech/angular-patch
