{if isset($js_defer) && !$js_defer && isset($js_files) && isset($js_def)}
{$js_def}
{foreach from=$js_files item=js_uri}
<script type="text/javascript" src="{$js_uri|escape:'html':'UTF-8'}"></script>

when i use w3 validator it give me error:
w3 validator error

You must add another condition
{if isset($js_defer) && !$js_defer && isset($js_files) && isset($js_def)}
{$js_def}
{foreach from=$js_files item=js_uri}
{if $js_uri}
<script type="text/javascript" src="{$js_uri|escape:'html':'UTF-8'}"></script>
{/if}
{/foreach}
{/if}
