Three shortcuts need no closure. Route::redirect() answers 302 by default, or the status you pass; Route::permanentRedirect() is the 301 form. Route::view() renders a Blade view with optional data. Route::fallback() answers when nothing else matches: the router skips it until every other route has failed, wherever it appears in the file.
Route::redirect('/shop', '/products', 301);
Route::view('/about', 'about', ['founded' => 2009]);
Route::fallback(fn () => response()->json(['message' => 'No such page.'], 404));$ curl -i http://127.0.0.1:8303/shop
HTTP/1.1 301 Moved Permanently

$ curl -s http://127.0.0.1:8303/about | grep '<p>'
<p>Selling books since 2009.</p>
$ curl -i http://127.0.0.1:8303/no/such/page
HTTP/1.1 404 Not Found

{"message":"No such page."}Redirect routes reserve the parameter names destination and status; view routes reserve view, data, status and headers. In web.php the fallback has sessions and could render a branded Blade page instead. It does not catch a missing bound model (Route Model Binding) or abort(404), which go through the exception handler; for one consistent page, create resources/views/errors/404.blade.php (Error Pages).
