Improvements to version 1.1 include a Dart2JS compiler that outputs JS more performant than hand-written code.
One of the biggest marketing bullet points for Dart has been its speed, but this has historically only been true within the custom-built Dart VM. Performance of the Dart VM began to overtake V8 in September 2012, and has remained in the lead ever since.
The most powerful way to push Dart adoption would obviously be to integrate its VM into the mainline Chrome browser, but there’s still no word of this happening. It seems the Dart team still have their work cut out in bringing the rest of their colleagues up to speed on their wunderkind.
