The DOM of a web page is comprised of HTML elements. These elements represent the layout and functionality of the web page. When a web page changes, it will be updated in the DOM. This helps improve the user experience. With React, the DOM doesn’t have to be reloaded each time a change occurs. It creates a Virtual DOM to store JSX elements and update them on demand.
