{{Short description|Proposed JavaScript-based scripting language}}

'''AtScript''' (now defunct) is a [[JavaScript]] based [[scripting language]] extending [[Microsoft]]'s [[Typescript]]. AtScript is created by [[Google]], it was announced in late October 2014 at the [http://ngeurope.org/ ng-europe conference].

'''AtScript''' was a proposed [[JavaScript]]-based [[scripting language]] extending Microsoft's [[TypeScript]] and [[Source-to-source compiler|transcompiling]] to JavaScript. It was introduced in October 2014 at the ng-Europe conference by the developers of [[Google]]'s [[AngularJS]] web development framework as the language that the upcoming Angular 2.0 would be built with.<ref>{{cite news|title=Angular 2 sera basé sur TypeScript : convergence de AtScript et TypeScript 1.5, c'est une collaboration entre Google et Microsoft|url=http://typescript.developpez.com/actu/82182/Angular-2-sera-base-sur-TypeScript-convergence-de-AtScript-et-TypeScript-1-5-c-est-une-collaboration-entre-Google-et-Microsoft/|access-date=3 May 2016|work=Developpez.com|language=fr-FR}}</ref><ref>{{cite web|url=https://www.youtube.com/watch?v=lGdnh8QSPPk |title=Miško Hevery - Keynote on AtScript at ng-europe 2014 |publisher=YouTube |date=October 28, 2014 |access-date=January 28, 2015}}</ref>

AtScript was originally intended to run on top of TypeScript, while including some features from [[Dart (programming language)|Dart]]. In October 2014, Google announced that Angular 2.0 would be written in AtScript.<ref>{{cite news|title=AtScript: Google's new superset JavaScript runtime - SD Times|url=http://sdtimes.com/atscript-googles-new-superset-javascript-runtime/|access-date=3 May 2016|work=SD Times|date=27 October 2014|language=en-US}}</ref> In March 2015, Microsoft announced that many of AtScript's features would be implemented in the TypeScript 1.5 release, and that Angular 2.0 would be built on pure TypeScript.<ref>{{cite news|title=Google, Microsoft to combine TypeScript and AtScript in Angular 2 - SD Times|url=http://sdtimes.com/google-microsoft-combine-typescript-atscript-angular-2/|access-date=3 May 2016|work=SD Times|date=5 March 2015|language=en-US}}</ref>

AtScript was created by Google's [[AngularJS]] team as the language of the upcoming AngularJS 2.0 web development framework.<ref>{{cite web|url=https://www.youtube.com/watch?v=lGdnh8QSPPk |title=Miško Hevery - Keynote on AtScript at ng-europe 2014 |publisher=YouTube |date=October 28, 2014 |accessdate=January 28, 2015}}</ref>

The name “AtScript” comes from the [[At sign|@ (“at”) symbol]] used for annotations in many languages (Dart,e.g. [[Java) annotation]]s and the[[Python “script”syntax word (as in JavaScript,and TypeScript,semantics#Decorators|Python CoffeeScriptdecorators]]).

The public language specification is currently a [[Draft document|draft]].<ref>{{cite web|url=https://docs.google.com/document/d/11YUzC-1d0V1-Q3V0fQ7KSit97HnZoKVygDxpWzEYW0U/edit |title=AtScript Primer |publisher=Google Docs |accessdate=January 28, 2015}}</ref> It states that plain JavaScript code ([[ECMAScript|ES5 or ES6]]) is valid AtScript code. AtScript is a [[superset]] of Microsoft's TypeScript. AtScript builds on ECMAScript 6 with types (through TypeScript), and extends it by [[Java annotation|annotations]] (type annotations, field annotations, metadata annotations) and type introspection. To sum up, AtScript is ECMAScript 6 with types, annotations and introspection.<ref>{{cite web|url=http://www.theregister.co.uk/2014/11/04/improving_javascript_google_throws_atscript_into_the_mix/ |title=Improving JavaScript: Google throws AtScript into the mix |date=Nov 4, 2014 |accessdate=January 28, 2015}}</ref>

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 is abandoned, features of AtScript will be implemented in TypeScript.<ref>{{cite web|url=https://www.youtube.com/watch?v=ihAeffWJEIc |title=State of 1 x - Pawel Kozlowski & Lucas Galfaso |publisher=YouTube |accessdate=March 5, 2015}}</ref><ref>{{cite web|url=http://blogs.msdn.com/b/typescript/archive/2015/03/05/angular-2-0-built-on-typescript.aspx |title=Angular 2: Built on TypeScript |publisher=Microsoft Corporation |accessdate=March 5, 2015}}</ref>
