That's backwards. React is a tool for writing declarative UI (or declarative anything really) that can handle state updates. Probably they're using it because it's the best tool around for that job.

React manages the state of the UI, all the props and the virtual DOM counts as state. The declarative part is that the UI is recomputed from the state sorta-ex-novo at each update

  Sure but the essence of it, the reason that it works, is that it shims a declarative architecture into JS. It works because it turns out UI programming works better in a declarative style.The fact that that involves managing state is secondary. I expect that in fifty years all programming will look declarative, either like HTML (which is sorta 'natively declarative') or more like React (which shims it into an imperative language).

    State management is not secondary, it is how it can implement the declarative UI with declarative updates.

      That is a silly way to phrase it. It's secondary in the sense that of course a UI framework has to manage state. They all do that if they're complex at all. The state management is not what distinguishes React from other frameworks; it is distinguished by the (pseudo-)declarative API that it presents to the programmer.

That parenthetical “or anything declarative really” is doing a lot of work, given that: React is a tool for writing 3D scenes that can handle state updates: https://github.com/pmndrs/react-three-fiber https://github.com/pmndrs/react-three-fiber React is a tool for writing music that can handle state updates: https://github.com/FormidableLabs/react-music https://github.com/FormidableLabs/react-music React is a tool for writing infrastructure-as-code templates that… um… could with some additional work handle state updates: https://www.linkedin.com/pulse/aws-terraform-generator-using-react-from-nitesh-bhat--3phpc https://www.linkedin.com/pulse/aws-terraform-generator-using...

  Well it depends if you're talking about React the UI library or React the increasingly popular underlying architecture. The former is vastly more popular by usage (I mean.. I assume) but the underlying approach to declarative-in-imperative turns out to work in other settings and seems to be gaining traction.
