Google has released an experimental build of Chromium that includes an integrated Dart language runtime. The browser, nicknamed Dartium, is being made available as a technical preview for those who want to see how the Dart virtual machine works in a browser.
Google launched Dart, a language for structured web programming in October 2011. Now the Dart team has released binaries (initially for Mac and Linux with Dartium for Windows billed as coming soon) that integrate the Dart VM into Chromium. This enables devs to run Dart programs directly on the Dart VM in Chromium and avoid a separate compilation step. The idea is that these programs will take advantage of the VM's faster performance and lower startup latency.
Chromium is the open source version of the Chrome browser so installing Dart into Chromium is a good way of testing it out before adding it to Chrome.
According to the Google blog, this is another step forward for the open source "batteries included" Dart platform. However, as a technology preview Dartium should not be used for day-to-day browsing. After more testing and developer feedback, the team plans to include the Dart VM in Chrome.
