Hi. In the official QML documentation we see the following suggestion ( http://doc.qt.io/qt-5/qtquick-performance.html):
>>> Use singleton types instead of pragma library scripts If you are using a pragma library script to store application-wide instance data, consider using a QObject singleton type instead. This should result in better performance, and will result in less JavaScript heap memory being used. <<< What does is mean? How should we use QObject singletons? For example, I have the following ".pragma library" JS to store application-wide constants: .pragma library var X = 10; ... many other declarations... How should I rewrite this with QObject singletons?
