I’m sorry but I’m a little confused. The painting of the ui is slow part right? So if the real dom receives changes at say node 4 from the virtual dom, does it not paint node 1, 2, 3 and 4 again? I guess my confusion is when you make a change in regular JavaScript to only node 4, how is that any different if the real dom is painting node 1, 2, 3 and 4 again. Perhaps I’m not understanding how the painting of the ui is done by the real dom
