commit dc7b140fa31cc8b2438859ceb8201e406528388c
Author: Mattias Bengtsson <mattias jc bengtsson gmail com>
Date: Wed Jan 22 07:53:32 2014 +0100
Use modern JS features
Since we run in a modern JS environment we are allowed to take advantage
of newer JS stuff like for..of-loops (loops over iterables) and
arrow-functions (anonymous functions that has lexical binding of
'this').
This patch makes us use the features mentioned above.
