I think that was parent's point. Coming from other languages, it's kind of unexpected that a var defined within a curly brace block (if/for/etc) is actually scoped on the whole function in which it appears and not just that block. Hence it's "useless" to define it within the block/loop -- might as well hoist it outside, it's visible there anyway
