dart (originally called dash) is a web programming language developed by google. it was unveiled at the goto conference in aarhus, 2011 october 1012. the goal of dart is "ultimately to replace javascript as the lingua franca of web development on the open web platform."
motivation:dart is intended to solve javascript's problems (which, according to a leaked memo, cannot be solved by evolving the language) while offering better performance, the ability "to be more easily tooled for largescale projects" and better security features. google offers a cross compiler that compiles dart to ecmascript 5, for compatibility with nondart browsers. google also plans to integrate a native vm into chrome (there is now a chromium branch available) and encourage competitors to do the same with their browsers.
