What are React Server Components, in simple terms?

Model answer

Server Components render on the server and send their output to the browser without shipping their JavaScript, so they can read databases or files directly and keep the client bundle smaller. Client Components (marked with "use client") handle interactivity and state.

They need a framework or bundler that supports them, such as Next.js, so check your framework docs.
