When all goes according to script Qt application development
summary
Explains why QQmlEngine (QML/V4) is a practical successor to deprecated QtScript by showing a working script runner that loads plain .js via a tiny QML wrapper, calls a specified function, and returns its QString result; demonstrates exporting QObjects with setContextProperty, built‑in Qt.include and console logging, timers and binding‑driven re‑evaluation, a URL interceptor for whitelist/resource loading, on‑the‑fly mock QObject types and widget instantiation — all running headless and successfully.
