Which statement about ReactDOM is true?

• A. A library that provides DOM manipulation functions for React
• B. A library for server-side rendering of React components
• C. A library that automatically updates the DOM without rendering
• D. ReactDOM is a JavaScript library that contains several React-specific methods, all of which deal with the DOM in some way or another.

Answer: (D)

ReactDOM is the JavaScript library that hosts React-specific methods for interacting with the browser's DOM. It is responsible for mounting and updating React components into the DOM (rendering and hydrating), unmounting components, and other DOM-related tasks that come from React’s rendering lifecycle. This makes it the official bridge between React’s component model and the actual DOM. The other statements aren’t accurate because server-side rendering uses a separate package (react-dom/server), and DOM changes happen as part of rendering rather than automatically without rendering.
