The only issue with declarative is when declarative is a prison instead of a fantastic and reasonable guideline. One of the very nice things about react is that you can escape pure declarative syntax to use actual javascript/typescript. Every declarative DSL/language/format that I've used has approximations like QML's [`Repeater`](https://doc.qt.io/qt-6/qml-qtquick-repeater.html), but eventually you will want and need some weird loop or logic that is most easily and succinctly expressed in a proper programming language -- at that point, you'll need to do some angry hack that unrolls one data structure into another so that you can iterate over that one with the limited logic in the declarative format. And then you'll have to keep the two models in sync.

All doable, just a pain.
