My problem with Dart is that it's just not that interesting from a language perspective. TypeScript is somewhat interesting in that it has a very low learning curve for JS devs, so that you can go straight to using ES6 maximally minimal classes and type annotations. The ability to jump straight in makes it worth a look. But Dart... Dart is a different (by similar) language that, therefore, has to be learned like any other language. And I simply have no desire to learn another traditional object oriented language that has all of the same features as other object oriented languages but with a "we do this one small thing better" proposition. You might say that this is the point, but I have to ask why they didn't just fully commit to GWT instead. If the point is to attract Java developers, that seems like the more logical way to go.
