How many years did it take JavaScript to become a multi-vendor standard? Let's see... Netscape Navigator 2.0 was shipped with it in September 1995 and ECMA-262 1st Edition was written in June 1997 and finally approved in April 1998. However, the 1st edition was done entirely by Netscape (by the looks of it). So, this doesn't count as a multi-vendor standard since there wasn't any involvement by any other vendor. Looks like you're being a bit unreasonable. Dart isn't even shipped yet in one browser and you're already complaining that it isn't a multi-vendor standard yet. Going by JavaScript's timeline, it still has more than 3 years for getting to that point.
