When using react, what appears on the user's browser?

edit

When using React, the user's browser will display the HTML elements and components that have been rendered by the React application. These elements and components can include text, images, buttons, forms, and other interactive elements that have been created using React's JSX syntax and rendered by the React DOM (Document Object Model) library. The user can interact with these elements and components, triggering state changes and updates within the React application, which are then reflected in real-time on the browser.
