Named routes are used to generate a URL or redirects to a specific route. The advantage of using a named route is, if we change the URI of a route in future, we wouldn't need to change the URL or redirects pointing to that route if we are using a named route. But if the links were generated using the url [ eg.
url('/admin/login')], then we would have to change everywhere where it is used.
Named routes are created using
as array key
Route::get('login', ['as' => 'loginPage', 'uses' => 'LoginController@index']);
or using method
To generate a url using the route's name
$url = route('loginPage');
If you are using the route name for redirection
$redirect = Redirect::route('loginPage');
