What is the difference between virtual dom and dom?

Question

JavaScript

When reading about the Virtual DOM, in all the materials they write that thanks to vdom, as a result, only those nodes that have changed are redrawn in the real dom.
But without the vdom, wouldn't the regular dom only redraw the nodes that I changed?
Example: there are two containers (neighbors to each other), if I add divs to one container, will redrawing occur in the neighboring container?

Answer 1

The point is not that, but that if you delete and immediately insert , this trivial replacement is cut off at the vdom level. This buffering allows you to draw each version of the page from scratch, and rendering occurs incrementally. <p>блабла</p><p>блабла</p>
