AtScript
AtScript (now defunct) is a JavaScript-based scripting language extending Microsoft's Typescript. It was announced by Google in late October 2014 at the ng-europe conference.
AtScript was created by Google's AngularJS team as the language of the upcoming AngularJS 2.0 web development framework.[1]
The public language specification is a draft.[2] It states that plain JavaScript code (ES5 or ES6) is valid AtScript code, as it is a superset of Microsoft's TypeScript. AtScript builds on ECMAScript 6 with types (through TypeScript), and extends it by annotations (type annotations, field annotations, metadata annotations) and type introspection. To sum up, AtScript is ECMAScript 6 with types, annotations and introspection.[3]
The name “AtScript” comes from the @ (“at”) symbol used for annotations in many languages (Dart, Java) and the “script” word (as in JavaScript, TypeScript, CoffeeScript).
In March 2015, the Angular team and Typescript blog announced that AtScript development was abandoned and that features of AtScript would be implemented in TypeScript.[4][5]
