If your website doesn't work without javascript, then it will be permanently broken for me and many others who disable it by default for very valid reasons. The has been part of the web since at least forever, so if your website doesn't support that, it's because your web developer isn't very good.

Yes, but the core ingredient in question is a food additive which may be necessary in industrial food, but has no place in a homemade pie recipe.

Some websites that display interactive data, and so forth, need javascript to work at all for that feature. But, most websites could provide basic functionality without javascript. What irks me is the requirement to run javascript to see anything at all. If you're displaying a blank page when I visit without javascript, that is a broken site, IMO. At the bare minimum display a message that javascript is required. From there, I can decide whether what you're offering is worth enabling javascript. Also, sites that demand I run every single script to see any content almost always ends with me leaving and never returning. Which, I suppose, is fine with the developer and owner, too.

Good grief. It's like pretending that progressive enhancement was never a thing. 🙄
