I find it notable when the blog of a major accessibility-focused company like Deque publishes an article called Debunking the Myth: Accessibility and React. Mark Steadman is essentially saying if a site has bad accessibility, it ain’t React… it’s you. The tools are there to achieve good accessibility.
React didn’t use a
<div> for a
<button>, you did. React didn’t force extra markup all over the page when you decided to not use a Fragment. React didn’t forget to change the title of the page because that was something you neglected.
Is it different how you have to do it in React versus how you have to do it in some other framework or CMS? Yes, it is. Different, but neither worse nor harder.
