<noscript> tag in HTML
The <noscript> tag is a container for alternate content to a script that's displayed when script support is absent or disabled.
The behavior and representation of this tag varies depending on whether scripting is enabled or not.
If scripting is disabled, this element represents its contents, otherwise, it represents nothing and browsers ignores it completely.
In the above example, it does not show the <noscript> content text, if the javascript is supported by browser.
