title: Can Angular have more than one bootstrap component?
body: <p>Stupid question alert:</p>
  
  <p>In our main app.module.ts file we set bootstrap parameter with value that defines our top-level component. So with this:</p>
  
  <pre><code>@NgModule({
    bootstrap: [AppComponent]
  })
  </code></pre>
  
  <p>We tell that when our module is used, our top-level component is AppComponent. But why it is in array? Can there be more top-level components...? </p>
