title: Switch case with Boolean
body: <p>I am trying to create a prefix text value for a project. I am using switch case for that. When the user select the relevant radio button we should give the prefix value.</p>
  
  <p>what should I give after the "switch ()"</p>
  
  <p>The value coming from user selection is a boolean value.
  The output is string.</p>
  
  <p>any help..</p>
