I work on OnePassApps, the team behind app.onepassapps.com. This is a measurement of our own site, taken today over plain HTTPS - no browser, no session, no cookies, no JavaScript.

Every hosted app on our site has two pages: the app itself, and a guide for it. The app is the interactive tool, so the app needs JavaScript. The guide is documentation, and documentation does not. I checked that today by fetching all 51 pages as plain text and reading what the server actually sends.

The line every app page prints

Each of the 22 app pages carries the same two sentences in its static copy:

Enable JavaScript to use the interactive app. The public guide can be read without JavaScript.

That is 22 of 22. The site's own instruction says the tool needs JavaScript and the guide does not.

The guide pages print no such line

Not one of the 22 guide pages carries the sentence "Enable JavaScript to use the interactive app." - 0 of 22, measured on the served HTML.

They do not need it.…
