Functional Reactive UI in Unity

jQuery is bleeding popularity with the front-end web development community, and for good reason: the current state of the DOM should be a pure function of the application state. The rise of React, Vue, Elm, and other functional paradigms has helped developers specify exactly how a UI can be written as a function of state.

Knowing this, I was _very troubled_ when I saw the UI preview touting a similarity to jQuery, now an infamously tangled mess and a poorly scalable way to develop a UI. I want a UI paradigm where I can functionally specify how my data is projected into an interface. I'm not interested in wrangling the transitions from one DOM state to another.

Does the next UI iteration feature or enable any kind of functional reactive paradigm?
