title: Are braces necessary in one-line statements in JavaScript?
body: <p>I once heard that leaving the curly braces in one-line statements could be harmful in JavaScript. I don't remember the reasoning anymore and a Google search did not help much. </p>
  
  <p>Is there anything that makes it a good idea to surround all statements within curly braces in JavaScript?</p>
  
  <p>I am asking, because everyone seems to do so.</p>
