title: Replace multiple characters in one replace call
body: <p>I need to replace every instance of '_' with a space, and every instance of '#' with nothing/empty.</p>
  <pre><code>var string = '#Please send_an_information_pack_to_the_following_address:';
  </code></pre>
  <p>I've tried this:</p>
  <pre><code>string.replace('#','').replace('_', ' ');
  </code></pre>
  <p>I don't really like chaining commands like this. Is there another way to do it in one?</p>
