To my knowledge java script is usually used, because it is easier to code than a plain page without. Since Claude etc become major enough to code complex stuff, it is relatively easy to vipe code complex but plain web pages without java scripts.
What is your opinion about the topic?
You can do some vibe Code if you chat enough about it with A.I. to understand every line of Code it suggested to you and you know it like the math axioms. In Reality some slight line and function try to hide complexity for you to have some time benefit. Which is kind of good because it saves time. But in between you have to share about ruling and just using computers with more trust in other code and not really understand it.
Its every time like a short cut and we like to use it. This is why mythos finds 271 Bugs in firefox before Version 150. You can do it but its just a quick fix until you know what and why are you use every line of code.
We have to vibe code. But try to use and break it before often from some new views… like energy efficiency like not sneaky selling meta data algorithms for google and some with exploits because the other use it too!
Like you got a boost with internet in 1990 by using Linux code and done the same mistakes offline before in math or by reverse engineer a driver for your mainboard.
I did a really bad job explaining my question, sorry. My question was more like from a view of website-users. We all probably visit vipe coded websites every day without our knowledge, but since ALA requires less effort to write plain web pages, they may become more popular again. So it can have a positive impact for the web (no need to activate JS for just a bit text). But of course, they also can vipe code java scripts.
I want to know if you think that is something good or bad and why you think so. Is it better to have a buggy slop coded plain JS-free page or a well programmed JS page? Such question I got in mind. You are also free to write about other aspects, but the visitor should be in focus, not the programmer.
Because the contents of the LLM brains are mostly only decided by large corporations, if it catches on for them to make all websites and not humans I find it pretty easy to believe the large corporations would manipulate that process until the LLMs were consistently making pages that require JavaScript and maybe also some random thing that helps corporations increase the level of dominion over the Earth.
I’m being cynical but it seems possible. As everybody onboards LLMs more and more – and in particular LLMs rented from server farms that aren’t even doing the work on their own computer – we will set ourselves up for the terrible but predictable future where a bunch of phone-addicts start voting and making laws that it should be illegal for humans to write code, because that is dangerous and they might create code that does not follow the rules. And then they will make a world where only LLMs are allowed to write the code.
At this brief moment in time what I am saying sounds insane. But if you could describe the world in 2026 to the people in 1986, it would probably sound even more insane.
And you don’t think LLMs are not used for JS right now? 
My question has some deeper thoughts about the future of webpages in general. Every non tech person now can create webpages without any coding experience. They can do it with JS or without and even without they can create super complex stuff. So will LLM prevent us from more JS code and is it worth it if the pages that still rely on JS may harm even more than JS already potentially does?
Why would someone even think about not using JavaScript at all? Some things are not possible without it. It’s not that it has real alternatives. Most modern frameworks also depend heavily on it.
Many pages work just fine without JS and many pages are using JS for the most simple things as showing text. You can do much more without JS than you probably think, but to my knowledge most hoster don’t do it, because plain HTML is a mess, even if things are doable.
Just see Codeberg vs Github when JS is disabled. Github is just unusable while Codeberg works for almost everything (there are little parts requiring scripts).
That doesn’t answer my question. 
Again, some things are not possible without JavaScript. Plain text sites could be created easily without LLMs but those are the vast minority on the internet.
Edit: But I get your point that it’s “overused”. JavaScript is just not bad per se.
I know that JS is not bad in general, but less JS means less attack vectors I need to worry about.
And I think you ask the wrong question. Why someone should create a page with JS if LLM creates one just without? I know that it was always possible without, but you see that most projects rely on for the most simple things and that has a reason and when this reason disappears … I think you get it.
I just saw a video yesterday where someone vibecoded its own webpage (for test purpose) and it looked like plain HTML with fancy effects.
It’s also possible you asked the wrong question. 
Most developers just don’t try to eliminate JavaScript only because they could; they use everything which helps moving to the goal (faster).
And since “developers” (or just chatbot kiddies) are using LLMs which don’t rely on JS, JS-less pages will be created. No guarantee, but more likely (and I saw an example, but not in English). 
I think JavaScript is abused. It is difficult or impossible for the user or the web browser to distinguish between good JavaScript and bad JavaScript.
