Language syntax has nothing to do with framework features, and especially things like writing UI components, managing state, and updating the DOM. The fact that the major frameworks have continued to explode in usage, and that we've seen new frameworks like Svelte and Solid come out, clearly says that the answer is "no".
Plus, why in the world is the post talking about "with the release of ES6", when that came out 6 years ago? I wondered if this was somehow a repost of something that had been written back in 2015, but a search on a couple phrases didn't turn up any other hits and the post does link to some other SO blog posts from 2017-18.
If I didn't know better I'd swear this was an April Fool's joke or a parody.
(and now that I scroll down further, it looks like the same thing's been said in the comments of that post)
