What is Javascript?
"JavaScript
is used for relatively simple functions such as popping up new windows,
or checking the information you type into a form to make sure it
conforms to what the receiving database expects. So, for example, it
will make sure that you have filled in all the required information or
that the postcode you've typed in is complete.
Many
people disable JavaScript in their browsers because it can pose
security risks. But some websites, especially social networking sites
like Facebook, will not work as well."

How do I know if I am a Non Javascript user?
You
are a non-JavaScript user if either your computer is unable to process
JavaScript or if you have chosen for your computer to not process
JavaScript in your browser's security settings. This is often done to
prevent pop-ups due to security risks, however it can prevent some
useful content working within the website.
If
you are a Non JavaScript user, the options to allow/use JavaScript will
be ticked within your internet options/security settings within your
web browser.
