What exactly is DDUI? Can it work with JSON UI and does it support animations?

[south condor]

Hey everyone!
I've been hearing about the new DDUI (Data-Driven UI) framework for Minecraft Bedrock scripting, and I'm trying to understand what it can really do.
From what I've read, it seems to be a reactive UI system using Observables and real-time updates, but I have some questions:
Can DDUI work together with traditional JSON UI files? Or is it completely separate?
Does it support UI animations? I've seen people mentioning they're doing animations with it, but I can't find this in the official documentation.
What are the actual advantages compared to the old server-ui module and regular JSON UI?
I'd really appreciate any insights, examples, or clarification from anyone who's been working with DDUI. If you know anything about this topic, I'd be grateful to hear!
Thanks in advance!

DDUI is separate to json ui and is very limited for now, its main source of usefulness at the moment is observables.

Basically variables (bindings if you will) can be dynamically changed and update in real time in the uis.

Meaning animations can be done externally from the form using changing values.

also modal form now has button*

but the animations only really involve hiding/showing elements and changing text

But is it planned to be a JSON UI replacement or just used for observables?

[hexed bear]

pretty sure they will coexist for a while but i think its a long term replacement

im not sure

Dear god please no, we already have the oreUI that's gonna replace the JSON one. We don't need yet another replacement, the old packs are going to become pretty much unusable.

DDUI IS OreUI

Yeah makes sense, I was wondering if that was the case.
