The HTML5 <noscript> tag is beneficial for both the document author and the web user. For browsers which have disabled scripts or if it is not supported by the browser, alternate content will be shown to the users. Authors of HTML document would not have to resort to other techniques to ensure the performance of the document while users are able to view the web page properly.

The HTML5 <noscript> tag is capable of handling all the content that has to be placed inside the body element of a particular HTML document.

Using the <noscript> tag is the same for both HTML4.01 and HTML5. It is also compatible with the major web browsers like Firefox, Google Chrome, Safari, Opera and Internet Explorer.
