Dart is a programming language developed at Google and approved as a standard by Ecma. It is ideal for web development and can be transcompiled to JavaScript, but can also be used to build server, desktop, and mobile applications. Dart is designed with a ‘batteries included’ philosophy and minimizes magic, such as automatic type coercion in order to avoid surprises when developing large applications.

Dart is used in products like Google AdSense, AdWords, Elections, and Shopping Express.
