title: jQuery Replace part of string using a variable
body: <p>This one seems simple, but I have no idea why it's not working.
  I would like to replace part of a string in a variable.</p>
  
  <p>Say, I have this code:</p>
  
  <pre><code>var url = "At vero eos et accusam et justo duo dolores et ea rebum.";
  url.replace('At vero eos et accusam et ', '');
  </code></pre>
  
  <p>Why doesn't it work?
  This one works:</p>
  
  <pre><code>var url = "At vero eos et accusam et justo duo dolores et ea rebum.".replace('At vero eos et accusam et ', ''):
  </code></pre>
  
  <p>-- but I'm using the variable elsewhere, so I would like to keep the replace  out of the variable definition.</p>
