The Angular team's mission is to make building web-applications easy on the web. We want to support as many languages as possible.

AngularJS supports: JavaScript and through transpilation CoffeeScript and TypeScript.

AngularDart obviously supports Dart. 

1) Dart is significantly different from JavaScript that transpilation approach would not create the experience we were looking for, for this reason we have rewritten it. 

2) Dart has Types, and Type annotations, and so while rewriting AngularDart we have chose to take advantage of these language features. 

3) We have also learned from our mistakes on AngularJS and taken the opportunity to correct them, such as much improved Directive API. Finally we have take advantage of the latest browser technologies and based AngularDart on top of Shadow DOM.

4) All of the learnings we have gained in building AngularDart, will be applied back to AngularJS v2. This is only expected since AngularDart is younger than AngularJS.

Angular is a philosophy on how applications should be built and we wanted to make the question of language choice orthogonal to your choice of using Angular. Any web-language you choose, there is an Angular you can use with it.
