Dart is a language and SDK created by Google for writing cross-browser maintainable JavaScript. It is also a working spec of the W3C - they're going to standardize it as a 2nd language that should be implemented by the browser. As a heavily smalltalk-inspired language with classical inheritance, it is much easier to write than today's JavaScript. It has test tools, type checking, and all the other niceties of a real programming language that wasn't designed in 10 days.
Because it compiles to JavaScript, and thus can be used today to write front-end applications. Angular has Dart support, though most other MVC front-end libraries do not as of now.
Not right now. We've already solved most of the problems it fixes.
