As far as I know, QVariantList and QVariantMap can convert to js array and js object, but that mean
qml part need to copy the data of js to c++, and c++ need to copy the data of js back to the qml. For small data,
this is not a problem. What if the data is quite big?Like millions of data need to process by c++ and display by the TableView of qml
Anyway to avoid copy but passing reference between c++ and qml?Thanks
