What is noscript tag?
As the name implies, we can use noscript to render alternate content. Anything within < noscript>< /noscript> tags will render only when JavaScript is disabled . Users might disable JavaScript for a number of reasons. A handful of people even install browser extensions like NoScript to prevent the browser from running JavaScript. It's better to have the default be non-javascript , and then let a javascript code overwrite with a javascript enabled page. example
<!DOCTYPE html>
<html>
<head>
<title>noscript</title>
</head>
<body>
<script type = "text/JavaScript">
document.write("Hello World!")
</script>
<noscript>
Your browser does not support JavaScript!
</noscript>
</body>
</html>
