Having trouble with a bit of javascript

Can anyone tell me why this bit of Javascript won't work when I paste it into it's own file and link to it? 

(function () {

  // Create mobile element
  var mobile = document.createElement('div');
  mobile.className = 'nav-mobile';
  document.querySelector('.nav').appendChild(mobile);

  // hasClass
  function hasClass(elem, className) {
      return new RegExp(' ' + className + ' ').test(' ' + elem.className + ' ');
  }

  // toggleClass
  function toggleClass(elem, className) {
      var newClass = ' ' + elem.className.replace(/[\t\r\n]/g, ' ') + ' ';
      if (hasClass(elem, className)) {
          while (newClass.indexOf(' ' + className + ' ') >= 0) {
              newClass = newClass.replace(' ' + className + ' ', ' ');
          }
          elem.className = newClass.replace(/^\s+|\s+$/g, '');
      } else {
          elem.className += ' ' + className;
      }
  }

  // Mobile nav function
  var mobileNav = document.querySelector('.nav-mobile');
  var toggle = document.querySelector('.nav-list');
  mobileNav.onclick = function () {
      toggleClass(this, 'nav-mobile-open');
      toggleClass(toggle, 'nav-active');
  };
})();

So I'm basically pasting that into a blank file called main.js then linking to it using:

<script src="main.js" type="text/javascript></script>

<script src="main.js" type="text/javascript"></script>

you're missing an endquote in your type attribute

Sorry that was just a typo. I've gone over everything like that a few times to double check I'm not being stupid.
