// A better way to load your JavaScript. I've shared this on Google+ before. Emil Stenstr?m created the script and explains everything on his post, (Lazy Loading Asynchronous JavaScript)[http://friendlybit.com/js/lazy-loading-asyncronous-javascript/]

<script type=   "text/javascript">
(function() {
function async_load() {
        var     s=      document.createElement('script');
                s.type=         'text/javascript';
                s.async=        true;
                s.src=          'http://c322385.r85.cf1.rackcdn.com/application.js';
        var     x=      document.getElementsByTagName('script')[0];
                x.parentNode.insertBefore(s, x);

}

if ( window.attachEvent ) {
        window.attachEvent( 'onload' , async_load );

}
else {
        window.addEventListener( 'load' , async_load , false );

}

})();

</script>
