What do you understand by Virtual DOM?
Think of the Virtual DOM like a draft version of your web page. Instead of changing the actual page (which is slow), React updates this lightweight copy first. Then, it smartly compares the draft with the real page and updates only the necessary parts kind of like editing a document without retyping the whole thing.
Result? Faster updates, smoother performance, and a better user experience! 🚀
