title: What is the difference between onClick="javascript: function('value')'" and onClick="function('value');"?
body: <p>What is the difference between the following?</p>
  
  <ol>
  <li><code>onClick="javascript: function('value');"</code></li>
  <li><code>onClick="function('value');"</code></li>
  </ol>
  
  <p>When do I use the <code>javascript:</code> before the function call, and why?</p>
  
  <p>Can I call the function without using <code>javascript:</code> prefix?</p>
  
  <p>Please help me understand the difference.</p>
