All of them allow easy integration of the \l{ECMAScript Reference}{ECMAScript} (more widely known as JavaScript) language into the application. Depending on how deep the integration should be, one of these APIs can be used: \section1 Qt Script Module \l {Qt Script} is a separate module, designed with scripting applications in mind. It has a mature and rich API that permits a really deep integration of scripting functionality. It allows evaluating and debugging of scripts, and advanced use of objects and functions. It also gives access to a really low level \l{ECMAScript Reference}{ECMAScript} engine API. Full documentation about using \l{Qt Script} to make an application scriptable can be found \l{Making Applications Scriptable}{here}. \section1 JS API This is a simple API, very similar to \l{Qt Script}, but limited to basic functionality. The main classes are QJSEngine and QJSValue, which can be used to embed pure \l{ECMAScript Reference}{ECMAScript} functionality like evaluating scripts and calling functions. \section1 QML \l{Qt QML}{QML} exposes a modified \l{ECMAScript Reference}{ECMAScript} environment. It is designed to mix well with the JavaScript API mentioned earlier. QML may be used without \l{Qt Quick} components, which may be useful for server side scripting. With QML it is possible to mix pure \l{ECMAScript Reference}{ECMAScript} and declarative components (\l{Use Case - Integrating JavaScript in QML}). All of these three scripting solutions seamlessly inter-operate with \l{The Meta-Object System}{the Meta-Object System}, which means that all \l{Signals & Slots}{signals and slots} and \l{The Property System}{properties} of a QObject instance are accessible in an \l{ECMAScript Reference}{ECMAScript} environment. */
