In das Polkit-Toolset, das in Distributionen zur Bearbeitung von Berechtigungen und zur Festlegung von Zugriffsregeln f\u00fcr Operationen mit erh\u00f6hten Rechten (wie z.B. das Einbinden von USB-Laufwerken) verwendet wird, wurde eine Backend-Funktionalit\u00e4t hinzugef\u00fcgt, die die Nutzung des integrierten JavaScript-Engines Duktape statt der zuvor verwendeten Mozilla Gecko-Engine erm\u00f6glicht (standardm\u00e4\u00dfig erfolgt weiterhin der Build mit der Mozilla-Engine). Die JavaScript-Sprache in Polkit wird verwendet, um Zugriffsregeln zu definieren, die mit dem privilegierten Hintergrundprozess polkitd \u00fcber das Objekt \"polkit\" interagieren. <\/p>\n

Duktape wird im Browser NetSurf verwendet und zeichnet sich durch seine kompakte Gr\u00f6\u00dfe, hohe Portabilit\u00e4t und einen niedrigen Ressourcenverbrauch aus (der Code ben\u00f6tigt etwa 160 kB, und f\u00fcr die Ausf\u00fchrung sind lediglich 64 kB RAM erforderlich). Es wird volle Kompatibilit\u00e4t mit den Spezifikationen von ECMAScript 5.1 und partielle Unterst\u00fctzung f\u00fcr ECMAScript 2015 und 2016 (ES6 und ES7) bereitgestellt. Zus\u00e4tzlich werden spezifische Erweiterungen angeboten, wie die Unterst\u00fctzung von Koroutinen, ein integriertes Protokollierungsframework, ein auf CommonJS basierender Modulladevorgang sowie ein Bytecode-Caching-System, das das Speichern und Laden kompilierter Funktionen erm\u00f6glicht. Au\u00dferdem sind ein integrierter Debugger, ein Engine f\u00fcr regul\u00e4re Ausdr\u00fccke und eine Subsystem zur Unterst\u00fctzung von Unicode enthalten.
