title: What exactly does "detach" method of ViewContainerRef Class in Angular do?
body: <p>Angular docs describes as:</p>
  
  <blockquote>
    <p>Use along with <code>insert</code> to move a View within the current container.</p>
  </blockquote>
  
  <p>But when I use it, it seems like, the component or whatever elements attached to it disappear somewhere. I can't see it in DOM.</p>
  
  <p>What does it exactly do?</p>
