Dart can be run in both modes. Chrome (dunno if enabled by default and/or in stable) contains a Dart VM, so you "only" need to transpile into JS for non-Chrome.

Dart can be run in both modes. Chrome (dunno if enabled by default and/or in stable) contains a Dart VM, so you "only" need to transpile into JS for non-Chrome. The main problem I had with Dart was [a year ago] that using existing JS libraries like jQuery wasn't as seemless as I would liked. So that would be a reason against Dart, if Angular wants to make that aspect easier. Haven't looked at TypeScript's interop with JS. I got frightened by the name Microsoft and the fact that they only had a huge language spec PDF and not a single tutorial or something easier to digest.

Not the real Chrome. A version of Chromium that you can use to make the development cycle smoother. When you deploy, you still transpile to JavaScript for all browsers.
