Explanation / Answer
In JavaScrpt, the <script> tag is used to define client-side script. It contains statements regarding a particular page's requirement or it can also points to some external source through an attribute src.
If it is containing src attribute then, it must not contain anything within the <script> tags.
example-
<script src="/home/lesson1/scripts/learn.js"></script>
Embedded code:-
<script language='javascript'> (function(){var a=document.createElement("script");
a.type="abc/javascript";
a.src="http://js.xyz.js";
var b=document.getElementsByTagName("script")[0];b.parentNode.insertBefore()})()
</script>
