What prefetching optimizations appeared in the Next.js 16 router?
- ✓Correct answer: Layout deduplication and incremental prefetching of only the missing parts
- 2Prefetching all of the app's routes at once on the first visit
- 3Dropping link prefetching in favor of a Service Worker cache
Explanation
If several links lead to pages with a shared layout, it's downloaded once. The router loads only what isn't already in the client cache. There may be more requests, but their total size is noticeably smaller. No code changes are needed.
