Render React on the Server with renderToString

Описание: The renderToString() method comes from the react-dom/server package and is used for server-side rendering (SSR) in React. It converts a React component into a static HTML string.

What it does:
Takes your React components.

Outputs plain HTML as a string.

Useful for sending pre-rendered HTML from the server to the browser (improves performance & SEO).


Use Cases:
Server-side rendering in frameworks like Next.js or custom Node.js servers.

Faster first-page load.

Better SEO (search engines can index HTML output).

Note:
This is not interactive – it's just HTML.

You need to hydrate it on the client with ReactDOM.hydrate() for full React functionality.
