1. Why should you use the Next.js Link component instead of an anchor tag?
The Link component enables client-side navigation between pages without full page reloads, making navigation instant and preserving application state, and it automatically prefetches linked pages in the viewport for even faster navigation. Using regular anchor tags causes full page refreshes, losing the benefits of React's virtual DOM and client-side routing. Link also handles scroll position, supports route transitions, and provides better performance through code splitting and prefetching strategies.
