Refactoring Code #2  

Hello, indexzero

I checked all of refactoring codes, and it changed some more stuff.
Also I tested with npm test command.
(But I couldn't find stylezero util anywhere. So I tested with vows --spec --isolate)
If it still not satisfied your style guide requirement, could you please answer for me?

Thanks :)
