Use the <noscript> tag to add a noscript section in HTML. The HTML <noscript> tag is used to handle the browsers which do recognize <script> tag but do not support scripting. This tag is used to display an alternate text message.
Example
You can try to run the following code to add a noscript section −
<!DOCTYPE html>
<html>
<head>
<title>HTML noscript Tag</title>
</head>
<body>
<script>
<!--
document.write("Hello JavaScript!")
-->
</script>
<noscript>
Your browser does not support JavaScript!
</noscript>
</body>
</html>
