Does SSR eliminate client JavaScript cost?
Short interview answer
No. SSR can deliver visible and meaningful HTML earlier, but interactive client components still require downloading, parsing, executing, and hydrating JavaScript. Server components or progressive enhancement can reduce what must reach the client.
Key takeaway
Explain the underlying mental model clearly, then support it with a concrete example and its trade-offs.
