Scripting engine

**QtScript** is a scripting engine that has been part of the [Qt](/source/Qt_(software)) [cross-platform](/source/Cross-platform_software) [application framework](/source/Application_framework) since version 4.3.0. It was first deprecated as of Qt 5.5, then dropped as of Qt 6.5, and replaced by Qt Meta-object Language ([QML](/source/QML)).

The [scripting language](/source/Scripting_language) is based on the [ECMAScript](/source/ECMAScript) standard with a few extensions, such as QObject-style signal and slot connections.[1] The library contains the engine, and a [C++](/source/C%2B%2B) application programming interface ([API](/source/API)) for evaluating QtScript code and exposing custom QObject-derived C++ classes to QtScript.

The QtScript Binding Generator[2] provides bindings for the Qt API to access directly from ECMAScript.[*[clarification needed](https://en.wikipedia.org/wiki/Wikipedia:Please_clarify) update needed?*] QtScript and the binding generator are used for [Amarok](/source/Amarok_(software)) 2's scripting system.

The QtScript version as of Qt 4.7 in 2011 uses [JavaScriptCore](/source/JavaScriptCore) but was developed no further. The module was deprecated as of Qt 5.5 in April 2015.[3]

## Qt Script for Applications (QSA)

An earlier and unrelated scripting engine, named *Qt Script for Applications* (QSA), was shipped by Trolltech as a separate Qt-based library, dual-licensed under [GNU General Public License](/source/GNU_General_Public_License) (GPL) and a commercial license.

With the release of QtScript, QSA has been deprecated and reached its end of life in 2008.[4]
