The Next.js Script component, next/script, is an extension of the HTML
<script> element. It enables developers to set the loading priority of third-party scripts anywhere in their application without needing to append directly to next/head, saving developer time while improving loading performance.
With next/script, you decide when to load your third-party script by using the strategy property:
<Script src="https://connect.facebook.net/en_US/sdk.js" strategy="lazyOnload" />
There are three different loading strategies that can be used:
beforeInteractive: Load before the page is interactive.
afterInteractive(default) : Load immediately after the page becomes interactive.
lazyOnload: Load during idle time.
