I don't understand what the purpose of using an IndexRoute and IndexLink. It seems that in any case the code below would have selected the Home component first unless the About path was activated.

<Route path="/" component={App}>

  <IndexRoute component={Home}/>

  <Route path="about" component={About}/>

</Route>

vs

<Route path="/" component={App}>

  <Route path="home" component={Home}/>

  <Route path="about" component={About}/>

</Route>

What's the advantage/purpose here of the first case?
