Why does server-side rendering (SSR) often improve the first load?
- ✓Correct answer: The user gets ready HTML right away, without waiting for JS to load and run
- 2The server is always faster than the browser, so the page loads instantly
- 3SSR completely removes the need to load JavaScript in the browser
Explanation
With CSR, the browser first gets almost empty HTML and waits for the bundle. With SSR, content is visible immediately, which improves LCP and SEO, but hydration still needs JS for interactivity. The cost is server load and response time.
