Do you think people will still turn off JavaScript 2-5 years from now?

It seems kind of ridiculous. What's the percentage of users actually experiencing this issue? 0.1%? Implementing this is only worth it for companies as big as google. if someone is browsing on a laptop that runs a browser that old from the 3rd world it's not even going to be a decent prospect for commercial purposes.

There are better methods for keeping people from visiting certain websites.

I just don't see where I would realistically implement this.

What's the "this" you are referring to? If it's in the video, can you give a time index?

I think you misunderstand how jQuery works. jQuery is a JavaScript library. It extends but does not replace JavaScript.

If you turn off JavaScript in your browser, then jQuery will also stop working.

The jQuery code is used to add a button only if JavaScript is enabled. Later in the video, the instructor points out that "if JavaScript is disabled our users will still be able to view the spoiler, but won't see a button that doesn't work."

This is also demonstrated in the video about 3 minutes in.
