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

'''AtScript''' is a language created to help developers read [[JavaScript]]. AtScript was announced in late October 2014 and similar to Microsoft's TypeScript, Google has created AtScript to improve JavaScript by providing a much easier way to manage it. AtScript is designed to work alongside TypeScript. AtScript is influenced by TypeScript but TypeScript lacks runtime introspection and metadata annotations. <ref>{{cite web|last1=Anderson|first1=Tim|title= Improving JavaScript: Google throws AtScript into the mix |url=http://www.theregister.co.uk/2014/11/04/improving_javascript_google_throws_atscript_into_the_mix/|website=http://www.theregister.co.uk/|publisher=The Register|accessdate=30 December 2014|ref=TheReg}}</ref> Enhancements include: Type annotations, Field annotations, Metadata annotations and Type Introspection with annotation support.

'''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>

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