Gotta say its pretty awesome! I can do a whole fully functional web app in about a 80kbs JS library(including embedded HTML for fast loading of different views).

The sweet thing about Dart is you don't need libraries like Angular or JQuery. I just use the built in Dart HTML methods and they compile down to vanilla JS.

JSON support is awful, "optional types" means "no types". Thanks, but even TS is better.

Enable strong mode. It's pretty neat - https://github.com/dart-lang/dev_compiler/blob/master/doc/ST...

While it is possible to write Dart code without using types (hence "optional") - the vast majority of Dart code is written using types.

The new Dart compiler also provides a "strong mode" which enforces strong typing in order to generate cleaner Javascript code.

Correct me if I'm wrong, but I thought that the majority of the Adwords frontend is still written in GWT?

It appears that the new version of the new AdWords UI is created using Dart and Angular 2: http://news.dartlang.org/2016/03/the-new-adwords-ui-uses-dar...

I'm not a heavy AdWords user, so I can't say for certain that this represents all of the AdWords UI. But based on the linked interview, it sounds like they replaced a lot of GWT with Angular.

The new Adwords is built with Dart.
