Keynote on AtScript
summary
Claim: AtScript is not a new language but ES6 plus optional types, metadata annotations, and runtime introspection. The team ships an AtScript compiler on Traceur that transpiles to ES5 and Dart and uses RTTS runtime checks in development to assert types and JSON contracts then strips them for production. Angular 2 is already authored in AtScript, the plan aligns with TypeScript and ECMA standards, and the approach proves practical for large teams and IDE tooling.
