After having been working with ReactJS for a while, I still can't get the benefit of Virtual DOM. The biggest benefit that you mentioned on your post is about "fast update" and "partial update". But the point here is updating in real dom is fast too, and after updating on Virtual DOM, you still have to go back to Real DOM to update it. What makes Real DOM slow is that after updating, Real DOM have to re-calculate style, layout (it's called repaint to something like that if I rememeber it correctly), so does Virtual DOM somehow solves that problem? Thanks!
Hi! Even I feel the same, I didn't compare the speed of the Real DOM and the virtual DOM, I just tried to explain how virtual DOM works in react and what happens behind the scenes.
It's just that since react has virtual DOM you don't have to update the DOM manually.
