title: What is the point of using empty statement in JavaScript?
body: <p>I tried to search for good resources on empty statement, but it seem like nothing show up. Even on <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/Empty" rel="noreferrer">MDN</a>, they don't have much to say about it.</p>
  
  <p>i.e: </p>
  
  <pre><code>for(var i = 0; i &lt; a.length; a[i++] = 0);
  
  if((a==0) || (b == 0));
  </code></pre>
  
  <p>I would like to know what are some real examples that one should use empty statements on their project. What are the reason behind it?</p>
