is virtual dom?
The dom that is possibly still not rendered, and awaiting changes.
Virtual DOM is just JS objects
So...dom is also js object
dom objects are objects of much more significance. when you change one, it re renders html, parses css properties, and re renders stuff on the ui virtual dom allows you to freely edit the dom nodes one by one, and then update it to the real dom at the end so you only trigger one big update
