What is Virtual DOM in React?

we'll be taking a deep dive into how the Virtual DOM (VDOM) works in React.

The Virtual DOM is a powerful tool that allows React to efficiently update the actual DOM by keeping track of a lightweight in-memory representation of the DOM tree. When a component's state changes, React calculates the minimal amount of changes that need to be made to the actual DOM by diffing the previous VDOM with the new VDOM.

We'll walk through a simple example of how the VDOM works, and see how it can improve the performance of our React apps by minimizing the number of DOM updates that need to be made.

By the end of this video, you'll have a solid understanding of how the VDOM works, and how it helps React maintain high performance even when dealing with large and complex component trees.
