Why Did Google Create Dart?

We want you to be able to create great web apps. Great web apps improve the web, and when the web does better, everyone wins.

Engineers at Google have been thinking about web apps for a long time. We’ve written a bunch of complex and widely used large-scale web apps (think Gmail, Google+, and Google Docs), so we’re quite familiar with the challenges of architecting web apps. We’ve also written a browser (Chrome) and a JavaScript engine (V8), so we’ve thought a lot about how to make web apps run faster.

Basically, we created Dart because we think it’ll help bring more great apps to the web, and we think it should be easier to create more complex web applications.
