title: Laravel Routing: Where is the prefix() Method Defined?
body: <p>In my example, I defined a route:</p>
  
  <pre><code>Route::prefix('home')-&gt;group(function(){
      Route::get('/test',....);
  });
  </code></pre>
  
  <p>When I access <code>mydomain/home/test,</code> it works. However, I don't know where the <code>prefix</code> method is located. I think it might be in <code>Illuminate\Routing\Route.php.</code> But when I remove the <code>prefix</code> method on that, is it still working?</p>
