title: Efficient way to remove delimiters from string in JavaScript
body: <p>I have to write several lines of code to remove delimiters from a string. Is there a more efficient way to remove all delimiters? Thanks.</p>
  
  <pre><code>    str = str.toLowerCase();
      str = str.replace(/ /g,'');
      str = str.replace(/\*/g, '');
      str = str.replace(/_/g, '');
      str = str.replace(/#/g, '');
      //etc....
  </code></pre>
