Dart’s co-founders Lars Bak and Kasper Lund wrote on the Dart blog:
Dart has features like mixins, method cascades, a rich core library, factory constructors, named parameters, ansync/await and a lot more.
But this isn’t the end of Google Dart. In the past, Google has killed many prospering projects. This announcement looks like opening up new paths for Google. Google’s biggest customer is Google Ads (AdSense and AdWords), which will be using Dart in future.
Google Dart is more than a programming language. Instead, it is a platform with capabilities like developer tools and libraries. It also functions like Node.js for server applications and real-time networking.
