That's true, but you need to read a lot from the (V)DOM when diff'ing. Which was said to be slow with the read DOM. I don't know to which extent, and I've read it's not true anymore.
I don't think the diff'ing is done with the real DOM, but between two VDOMs. No?
Anyway, I personally find this approach heavy and like more how Svelte patches the DOM instead of computing a diff.
