title: Should a function use: return null;?
body: <p>Should a function return <code>null</code>?</p>
  
  <p>E.g.</p>
  
  <pre><code>function test()
  {
      return null; // vs return;
  }
  </code></pre>
  
  <p>Is the latter considered bad practice or doesn't it matter?</p>
  
  <p>PS</p>
  
  <p>Whether it is bad practice shouldn't be subjective IMHO.</p>
