⚡ Why React’s Virtual DOM Makes UI Faster

React uses a Virtual DOM to make updates super efficient. Instead of directly updating the real DOM (which is slow), React first updates a lightweight copy — the Virtual DOM.
.

🎯 How it works:
• React creates a Virtual DOM copy of the real DOM
• When state changes, React updates the Virtual DOM
• It compares old vs new (called diffing)
• Only the changed parts update in the real DOM

🔧 Example:
If just one list item changes, React updates only that item, not the entire list.

📌 Benefits:
• Faster rendering
• Smooth UI updates
• Better performance in large apps

The Virtual DOM is one of the main reasons React is so popular today.
