Why does this Google close line look like this?

Question

Why does this javascript line look like this? I mean, why is there an extra + near the end?

'<script type="text/javascript" src="' + src + '"></' + 'script>'

Answer 1

Because if you have a "</script>" inside the <script> , the browser will think that you have closed the script tag. This is a fairly common way to include text </script> inside a string in <script> tags.
