Lars Bak, Kasper Lund

Dart is out of beta: 1.0

• open sourced: www.dartlang.org (BSD License)
• structured programming language
• reliable libs
• IDE (based on eclipse)
• dart2js translator
• ongoing development (speed, more compact, standardized etc.)

Dart

• abstraction mechanisms
• optional static types (type annotations)
• can be combined with existing Javascript: https://github.com/dart-lang/js-interop

IDE -- Dart SDK1.0

• special Chromium with DartVM integrated
• integrated debugger
• automatic update on code changes
• code completion

Real Dart Projects:

• Montage (Mixbook): nice photo book tool
• Blossom - agile project management tool
• GreanTea Project - internal Google project
  • Angular ported to Dart: AngularDart https://github.com/angular/angular.dart
  • subprojects:
    • shadowdom http://www.html5rocks.com/en/tutorials/webcomponents/shadowdom/
    • Streamy https://github.com/google/streamy-dart
    • route https://github.com/dart-lang/route
    • Polymer.dart

Performance of Dart:

• best on native Dart VM
• converted to JS: comparable to JS
• startup performance imporved because of snapshot mechanism (Dart VM only)

Dart outside the browser:

• standalone
• IO libs (networking, file, ...)
• cpus: ARM, MIPS, x64
