> What I really meant is that if you have a significant non-JS-supporting visitor base, you almost certainly already know it. There are a huge class of web apps that simply do not have to worry about it. If you know who your customers/visitors are then you should already know how important it is to support non-JS browsers. I was refering specifically to websites, not webapps. > It's really not the end of story, and it's not your call except for your own web apps. JavaScript is an integral part of the platform that is the web, just like HTML and CSS. You might as well make the argument that "requiring a web browser for your app is not okay, end of story." That analogy makes absolutely no sense, nor does your comparison to CSS. JS is an entirely different class of dependency than either CSS or web browsers. JS is turing-complete, has a significantly bigger attack surface (both in terms of vulnerabilities and in terms of tracking), is much, much harder to optimize for a low-powered device than HTML and CSS, and so on. Further, the web browser is a necessity to view something on the web. It is well understood, it is easy to optimize, and it is widely deployed. JS is no such 'required dependency' - and you should not make it one, when it can be done just fine without. > Things were a lot different 10 years ago, and perhaps your reluctance to update your understanding less than once per decade might explain some of your views. You may as well be saying "making a store than can only be accessed over the Internet is not okay, end of story, we all collectively understood this 25 years ago." The support/compatibility landscape for JS has not changed in those 10 years. The types of non-JS clients are still the same, the reasons for progressive enhancement are still the same. The only thing that has changed is standardization. "Old" is not the same as "obsoleted". Unless you can come up with a concrete reason as to why this knowledge has been obsoleted throughout the past 10 years, it still applies. And I'm getting a little tired of these poorly fitting analogies, you're using them as a crutch.
