How to create object properties in JavaScript?

Answer»

To find whether the web browser supports JavaScript or not, you can TEST it on your local system.

Create an HTML file and USE the <noscript> tag. Run the file in your browser and if it does not support JavaScript, then the message set under the <noscript> would be visible.

The <noscript> tag is used in JavaScript to allow adding an alternate message if JavaScript is disabled in the web browser. In this WAY a user can know whether the web browser has JavaScript or not. If it’s not there, then the message ADDED using the <noscript> is visible.

The following is an example:

<!DOCTYPE html> <html>    <head>       <title>HTML noscript</title>    </head>    <body>       <script>          <!--             document.write("This is demo text!")          -->       </script>       <noscript>          Your browser does not support JavaScript!       </noscript>    </body> </html>

The above code will allow the web browser that doesn't support JavaScript to display the text which we added under <noscript> tag i.e. "Your browser does not support JavaScript!".
