btw, why you want render() in another framework?

Not exactly the same as React render(), I have started an experimental project to update QML UI by diff:

QSyncable - Synchronize data between models

p.s In fact, Qt Scene Graph is somehow similar to React. Both of them will only apply the changes to screen. React manipulates the DOM, but Qt manipulates the OpenGL render pipeline.
