Hold on a minute, Firefox is way ahead of Chrome when it comes to ECMAScript Harmony support.
Some googlers do not believe that JavaScript can continue to grow and they will launch a new language. This sounds like VBScript 2.0 to my ears.
So Google is (a) lying about ES Harmony support and (b) trying to disrupt the universal nature of the web.
Time for the employees to read the company motto about evil again!
