What is sent to the browser when Server Components render?
- ✓Correct answer: A serialized description of the rendered tree (the RSC payload), with references to client component code
- 2The source code of the server components
- 3Only plain HTML, no JavaScript ever
Explanation
The payload lets React merge new server output into the existing client tree without losing client state. Server component code itself never ships to the browser.
