How to handle when JavaScript is turned off?

Javascript Web Development Front End Technology

Nowadays, almost every web browser supports JavaScript. If it is turned off, you can use <noscript> tag. To let users know about non-JavaScript web browsers, use the <noscript> tag. 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

<!DOCTYPE html>
<html>
   <head>
      <title>HTML noscript Tag</title>
   </head>
   <body>
      <script type = "text/JavaScript">
         <!--
            document.write("Hello JavaScript!")
         -->
      </script>
      <noscript>
         Your browser does not support JavaScript!
      </noscript>
   </body>
</html>
