HTML comment within <script> tags

Are HTML comments within script tags ignored? Or does commented out code not run? For example: <script> <!-- window.onload = alert('test'); --> </script>

It is ignored.


Thanks. I've seen it being used on a website but it seemed to be done as a form of code obfuscation. It used unescape('long string of characters'); I assume it's to prevent web scraping maybe.
