Echo JS 0.11.0

Only minor nit I would pick is that in most of the cases in the refactored code, `else` could be removed.  More often than not, `else` is a code smell imho, and often you're better off separating function logic and having an early return instead of an else.

John Carmack makes some good arguments against fine-grained splitting of functions: http://number-none.com/blow/john_carmack_on_inlined_code.html

Use in moderation.
