App developers from all platforms should be able to build for the modern web, but many non-endemic web developers have different expectations and requirements from their language, tools, and development platform than what is available today. We believe there is room for a new platform, one that is not encumbered by 15 years of cruft, that is familiar to developers of different backgrounds, and that is structured to enable the larger, more complex apps that users are demanding.

We don’t think JavaScript is going away. In fact, Google is actively working with TC39 to improve JavaScript, and new features are already landing in V8 and Chrome. However, our commitment to improving JavaScript doesn’t prevent us from thinking about other solutions. For example, Dart will take advantage of the continued work on JavaScript, because Dart programs compile to JavaScript to run across the entire modern web.
