title: jquery cookie set value to boolean true
body: <p>I am using this <a href="https://github.com/carhartl/jquery-cookie" rel="noreferrer">jquery.cookie</a> plugin and I need to set value to TRUE or NULL/FALSE.</p>
  
  <p>I am trying to do it like this: <code>$.cookie('ff', true, { expires: 30, path: '/' });</code> but it sets the value to string and not boolean.</p>
  
  <p>Any ways of fixing this?</p>
