Dynamic Segment

You can designate a route segment as dynamic with [] so that it accepts any path segment.

Different actions can then be taken according to the actual segment passed in the URL.

When content is retrieved using a fetch request within the generateStaticParams() function, the requests are automatically memoized. This ensures that a fetch request with identical arguments, whether across multiple generateStaticParams, Layouts, or Pages, is executed only once. Consequently, this reduces build times.
