title: In Scala, why 'case object' and not just 'object'?
body: <p>I read and understand, <code>case class</code> is to send arguments and create multiple object and <code>case object</code> don't send any arguments and having single object. So that will achieve by <code>object</code> also why <code>case object</code>.</p>
  
  <p>Why is <code>case object</code> important and when? I already gone through this post, but I did not get why <code>case object</code>. </p>
