You mean www.nytimes.com ? Is that already the new react powered version?

As a sidenode, it does feel sludgy:

- Scroll is not smooth.

- It does not adapt well to different browser sizes

- After a few seconds the page "jumps down"

But the reason might simply be the overkill of JS,animations, overlapping elements (like the static header), ads, dynamically loaded stuff and other crap. When I turn off JS, some of the problems go away.

They're not using React right now. If you read the article it says they'll be introducing the new version over the next several months.

A lot of this "JS is slow, what happened to good old HTML and CSS, get off my lawn" stuff is simply confirmation bias.

I didn't look close enough in the developer tools to see the limited extent. From what I can see, just the email list sign-up forms on www.nytimes.com are using React, but all of the new front page of mobile.nytimes.com is in React. They are testing the new version of the mobile site in a partial roll-out, so if you open a new browser session there's a good chance the new one will get served to you (It will have a message saying "You’re seeing a test of a new version of the New York Times home page.").
