In short
Proactively fetching a resource (like the next page's JS/data) before the user actually navigates to it, so the transition feels instant.
How to learn this
- 1Notice how Next.js's `<Link>` automatically prefetches linked pages in the viewport.
- 2Learn `<link rel="prefetch">` for manually hinting future navigations.
- 3Understand the trade-off: prefetching uses bandwidth the user may not need.
