I'm the author of CxJS[1] which uses React for rendering. Before rendering, the whole tree is scanned for data changes and with that information available shouldComponentUpdate is very simple.

Another technique that I find very useful is to use a dedicated data declaration component which then decides if children should update or not. Try grid sorting on this page: https://worldoscope.cxjs.io/yyrsmjk
