Context: I'm using Dart for app development for two years now. > Not all language features can be represented in JavaScript. I could not name one (except the dart:io stuff, which is not supported in the JS world). Could you please elaborate? > Besides, all the languages that compile to JavaScript just add complexity layers to the already complex model of HTML/CSS/JavaScript. I've found the same, but Dart is a surprising exception. If you are not using any fancy framework (e.g. Angular.Dart), you will be just fine with the close-to-the-browser approach of the language and APIs.

The main example is that Dart's basic numeric types can't be represented in JavaScript. Dart VM integers are bignums, while dart2js numbers are IEEE754 doubles.

  That's for performance because I guess the majority of users would probably not notice the difference. They can be represented in JS, but not natively.

    Yes, the decision to make numeric types incompatible between the VM and dart2js was due to speed concerns.
