I am banging my head trying to find the error in this code. I have checked it so many times can someone point out where the problem is?

$(function() {

  try {

    function endswith(str, ends) {

      if (ends === '') return true;

      if (str == null || ends == null) return false;

      str = String(str);

      ends = String(ends);

      return str.length >= ends.length && str.slice(str.length - ends.length) === ends;

    }

    var referrer = new URL(document.referrer).domain;

    if (endswith(referrer, xyz.com)) {

      $(.logo .logo-external).remove();

    } else {

      $(.logo .logo-internal).remove();

    }

  } catch () {}

});
