I'm really intrigued by Next.js's support for caching strategies and partial rendering. These can offer significant improvements in performance and caching and improve the overall user experience!!

Additionally, the next/after API is going to help in more efficient resource management by allowing secondary tasks (logging, cleanup activities) without blocking the primary tasks.

And not to mention what looks like a game-changer: "Turbopack," specially built for Next.js to overcome some of the web pack's performance limitations.

Going to deep dive into these soon!! Thanks for sharing.
