Laravel 9 provides shorter version of redirect()->route(), take a look on the following code:
// Old wayRoute::get('redirectRoute', function() {    return redirect()->route('home');}); // Post Laravel 9Route::get('redirectRoute', function() {    return to_route('home');});
This helper work in the same way as redirect()->route('home'), but it is more concise than an old way.
