Use virtual-dom for questions related to an object model which mimics the structure of and intercepts events normally handled by the real document object model (DOM).
The virtual-dom applies of the technique of double buffering to the DOM. It is used for many purposes, including:
security: sandboxing DOM mutation
performance: minimization of repaints and reflows
testing: performing static analysis on the rendered tree
Can someone explain some React issues,? How can ref (from useRef, for example ) in component be the same if VirtualDOM creates NEW objects in every rerendering? This means that ref to that object should be differ from the previous one
I read the article https://dev.to/karthikraja34/what-is-virtual-dom-and-why-is-it-faster-14p9
There is example of code, example must help us to understand answer on the question - "Why do we need virtual DOM?"
From article:
For example: Let's say…
i have a component with modal popup and defined a viewchild elementRef to try to get an element of input text after the modal popup opens. The modal is opened after click a button and there is a search button in the modal triggers a function in…

For example consider this code:
