title: JavaScript! window.onload = someFunction and window.onload = someFunction()
body: <p>Is there a difference between:</p>
  
  <ol>
  <li><p><code>window.onload = someFunction;</code></p></li>
  <li><p><code>window.onload = someFunction();</code></p></li>
  </ol>
  
  <p>The parentheses at the end. Do they make any difference?</p>
  
  <p>We generally use the first one! What if we Have to pass some parameter to the function. How will we do it by using the first statement?</p>
