Utopistically, how nice would be if the whole web provided no-javascript versions of the sites? In the end 90% of the cases javascript is used just to do fancy things, while actual functionalities could be achieved with much less pain (and vulnerability).
I think this would have been true a few years back, but I think more and more web-sites are using javascript in irreplaceable waves. I suspect javascript will become increasingly necessary as frameworks like angularjs become more popular. That said, if you are just interested in buying a pizza, or reading a blog post, then maybe javascript will never be really necessary.
