DOM (Real DOM)
Tree Structure of HTML elements.
Dom (Document Object Model): The true structure of HTML elements in web page.
Managed directly by the browser.
Updating the real DOM is slow, because even a small change can re-render the entire page.
React Dom (Virtual DOM)
React is a library (react-dom) to interact with DOM.
Connects React with the browser DOM.
React first updates the Virtual DOM.
Then React Dom updates only the changed parts in the real DOM efficiently.
