next/script component và loading strategies là gì?

next/script tối ưu loading third-party scripts.

• Strategies: beforeInteractive (trước hydration, cho critical scripts), afterInteractive (sau hydration, default), lazyOnload (idle time), worker (web worker với Partytown).
• Tránh dùng thẻ script thông thường trong App Router, dùng next/script thay thế.

next/script optimizes third-party script loading.

• Strategies: beforeInteractive (before hydration, for critical scripts), afterInteractive (after hydration, the default), lazyOnload (during browser idle time), worker (offload to a web worker via Partytown).
• Avoid raw script tags in the App Router — use next/script instead.
