Re: React and screen reader accessibility?

Hello,

How does using a virtual DOM change the fact that using HTML in the
finished product is better than using a thousand div elements styled with
CSS?

In fact, I think it would be easier to make sure the finished product is
accessible. You don't have pesky programmers not following an official
coding practice messing with the final result in React.



I also think that there are sometimes when a user wants to be alerted and
sometimes when alerts are just annoying. I personally dislike alerts
telling me when the content changes, but in chat clients or normal alerts,
I like my screen reader to read aloud what is going on.



I think it is even worse that react has complete control over the rendering
and it is not accessible out o of the box through extensive html usage and
user testing. It is a shame that the data tables and intro tutorial are not
accessible.

I'm just wondering how there could be such a big divide between what FB
says and what react does.

Thanks,
