Answer

To detect if JavaScript is disabled on a page, you can use the <noscript> HTML tag. This tag allows you to display content or messages to users who have JavaScript disabled in their browsers. For example, you can include a message within the <noscript> tag to inform users that JavaScript is required for the full functionality of the page.
