Key difference between App router and Page router :

App Router:
• File-based routing: Uses nested folders to define routes.
• Components: Server Components by default.
• Data fetching: Uses fetch function.
• Layouts: Can be nested and dynamic.
• Dynamic routes: Supported, but syntax differs.
• Client-side navigation: Supported with router.push.
• Priority: Takes precedence over Page Router.
Page Router:
• File-based routing: Files directly represent routes.
• Components: Client Components by default.
• Data fetching: Uses getServerSideProps, getStaticProps, getInitialProps.
• Layouts: Static.
• Dynamic routes: Supported.
• Client-side navigation: Supported with Link component.
• Priority: Fallback if no matching route in App Router.
