Kevin,

Do you follow the news at all?

Just a couple of weeks ago there was a bunch of stuff about a Java zero day
flaw and everybody and his brother discussed how to turn off java script.

I'm with Pete, I use noscript to disable Java script for any new site a
browse to.

15 years ago I would have agreed with you Pete.

Your average Joe using the Internet these days wouldn't even know what
JavaScript was let alone why or how to disable it.

Are you seriously saying you do a full analysis of the JavaScript
functionality on a new website before allowing it? Wow! You either need a
medal, or psychiatric help :)

How do you perform this analysis when using your mobile device(s), or do
you steer clear of those?

"Why would anyone turn off JavaScript support these days"

Because javascript is one of the most popular attack vectors out there.
CSRF, XSS, drive bys, you name it. Javascript does plenty in the
background that we never see and that is why it is so popular with
hackers. I never enter a new or unknown site with Javascript enabled in
my browser and I take a look at what it is attempting to load before I
allow it to run. I use the noscript plugin and it has saved my rear end
multiple times....

Now *leaving* javascript disabled is another story, but entering a site,
yeah, turning off javascript makes for a funky experience but well
designed sites still deliver content without it and give you a heads up
about what the site won't provide when javascript is off.

they don't have any interest in using the Internet? Turning it off would
preclude you from using almost every modern website there is.

I guess the point is, why would Nathan need to demonstrate his example
working without JavaScript support? That would be almost as pointless as
demonstrating it without CSS support.

Lack of a mouse, on the other hand, is a valid point. You should be
able to navigate to any clickable element with the keyboard and hit enter
to trigger the event - but that requires JavaScript:)
