title: Strip hashtags from string using JavaScript
body: <p>I have a string that may contains Twitter hashtags. I'd like to strip it from the string. How should I do this? I'm trying to use the RegExp class but it doesn't seem to work. What am I doing wrong?</p>
  
  <p>This is my code:</p>
  
  <pre><code>var regexp = new RegExp('\b#\w\w+');
  postText = postText.replace(regexp, '');
  </code></pre>
