laravel/route/php question?

Hey/Hi, I realize that this isn't a specific laravel channel, but -- here's the question. New to laravel, trying to track down how/where a statement in a file within a test laravel works. the test file resources/views/layout/app.blade.php the line.. <a href="{{ route('properties') }}">PProperties</a> which then generates <a href="/">PProperties</a> so in some function/method route('properties') ==> "/" or route:get "properties" gets xferred to "/" but, so far, I can't seem to track down where this might happen, or the flow of the logic. If anyone has any pointers, feel free to fire them to me! thanks
