Try Dart 1 hour experience first draft

src/site/articles/trydart/examples/1-blankbadge/piratebadge.dart.js

+// Generated by dart2js, the Dart to JavaScript compiler.
+// The code supports the following hooks:
+// dartPrint(message)   - if this function is defined it is called
+//                        instead of the Dart [print] method.
+// dartMainRunner(main) - if this function is defined, the Dart [main]
+//                        method will not be invoked directly.
+//                        Instead, a closure that will invoke [main] is
+//                        passed to [dartMainRunner].
