Dart 1.0: A stable SDK for structured web apps

Dart SDK 1.0 has been released as a stable, cross-browser, open-source toolkit for creating structured web applications, marking its evolution into a production-ready option for developers. This release includes a powerful programming language, robust tools such as Dart Editor and Dartium, comprehensive core libraries, and the dart2js translator, which enhances the performance and reduces the code size of generated JavaScript. The SDK also features the Pub package manager with over 500 community packages, including popular frameworks like AngularDart and polymer.dart. Dart aims to simplify and scale development workflows, offering features like code completion, refactoring, and debugging. It supports asynchronous server-side computation and allows interoperation with JavaScript libraries. The performance has significantly improved, with benchmark results showing Dart VM surpassing idiomatic JavaScript in speed. Companies like Blossom, Montage, Soundtrap, and even Google's internal applications are already using Dart in production, and other companies such as Adobe and JetBrains are adding Dart support to their products. The Dart team plans to focus on enhancing Dartium, further improving performance, and maintaining backward compatibility with core technologies.
