New MIME type "application/dart"... I suspect that Google Chrome will embed a Dart Runtime when it gets stable, that will be very interesting; I'm not sure if it's a good or a bad thing though.
OTOH it's not that uncommon these days, especially when these transpiled-to-js languages want to run without being translated ahead of time (though usually in production you would want to do that offline)...text/coffeescript, text/traceur, text/es-harmony, etc etc
Yeah, but I don't think any of these mime-types represent any threat for today's Javascript. OTOH Dart(or Dash)'s sponsor already gave us some clues of that their intentions are. I quote https://gist.github.com/1208618 "Push for
Dash to become an open standard and be adopted by other browsers. Developers
using Dash tooling will be able to use a cross-compiler to target Javascript
for browsers that do not support Dash natively." again, it says "target Javascript
for browsers that do not support Dash natively [for now]."
