title: What use is redirectTo?
body: <p>I understand that redirectTo redirects a route to a given component for example if you wanted to redirect the root of your app to a specific URL you might originally have this:</p>
  
  <pre><code>const routes: Routes = [
    { path: '', component: HomeComponent }, 
    { path: 'login', component: LoginComponent },
    { path: 'dashboard', component: DashboardComponent}
  ];
  </code></pre>
  
  <p>And if you wanted to change this so that the '' redirected you to the dashboard you might do this:</p>
  
  <pre><code>const routes: Routes = [
    { path: '', redirectTo:'dashboard', pathMatch: 'full' }, 
    { path: 'login', component: LoginComponent },
    { path: 'dashboard', component: DashboardComponent}
  ];
  </code></pre>
  
  <p>That clear enough, but wouldn't this be easier?</p>
  
  <pre><code>const routes: Routes = [
    { path: '', component: DashboardComponent }, 
    { path: 'login', component: LoginComponent },
    { path: 'dashboard', component: DashboardComponent}
  ];
  </code></pre>
  
  <p>Unless you specifically wanted to do a redirect, maybe for SEO reasons or tracking or something then wouldn't the second option be clearer? </p>
