Dart's logo
Dart is a new scripting language created by Google. It was created because there were multiple problems the Google staff had with JavaScript, and they hoped Dart could fix those problems and eventually replace JavaScript. The Beta 1 Preview Release was on June 19, 2013.
Official Description[]
With the Dart platform, you can write code that runs on servers and in modern web browsers. Dart compiles to JavaScript, so your Dart web apps will work in multiple browsers (not just ours).
The Dart platform includes a language, libraries, an editor, a virtual machine (VM) for both servers and browsers, and a compiler to JavaScript.
