You probably misunderstood : allmost all websites require javascript, yes - but you can selectivly allow only the javascript of that site, their framework etc. and block all the tracker/ads javascript with NoScript/UBlock - and then it is working and probably quite safe. But to mitigate, more and more websites find ways to sneak in the tracker/ads/analytics into the main sites js. So it is not as easy, either.

Which is why I just use basic ublock origin and regulary wipe the browser cache.
