JS is not typecast correctly

[maximus-sallam]

On lines 354, 355, 356, and 357 of index.html, the JS assets are not typecast correctly. It should be updated as follows to prevent errors in the browser:

                    <script type="text/javascript" src="assets/js/jquery.min.js"></script>
                    <script type="text/javascript" src="assets/js/skel.min.js"></script>
                    <script type="text/javascript" src="assets/js/util.js"></script>
                    <script type="text/javascript" src="assets/js/main.js"></script>
