Originally announced and previewed back in October 2011, the Dart language has been variously billed by Google as "a new language for scalable Web app engineering" and "a language for structured Web programming."
The language is reminiscent of C++ and C#, but one of its most touted features -- not shared with those languages -- is optional typing. Google claims this allows for rapid application development, since types can be added later as needed, and there is no discernible impact on performance either way.
Right now, though, no browser runs Dart -- not even Google's own Chrome. Instead, Google has a special build of Chromium, Dartium, which implements the Dart VM and is shipped with the Dart Editor and Dart SDK. No timeframe has been given as to when Dart would be added to Chrome, even as an unstable opt-in feature.
