This used to be true, but now I don't think it is anymore. Modern frameworks and modern screen readers have no issue with acessibility.

Some survey from WebAIM found that 99.3% of screen reader users have JavaScript enabled.

So... are they really in accessibility territory still? Only people I still see complaining about Javascript being required are people that insist the web should just be static documents with hyperlinks like it was in the early 90s.

Can you find a modern source with valid reasons for accomodating non-JS users?
