Looking at the examples, $subj is a classic retained-mode gui, just like Qt, GTK, Wx, Tk, FLTK, MFC, VCL, App/UIKit and so on. Widget tree and methods and event callbacks. DOM is also that, although a little crappier in some parts. You want to document.createElement(), el.setAttribute(), el.appendChild(), el.addEventHandler(). This obvious interface got buried under the all-consuming react dogma, but it's still there. jQuery and alikes (zepto, umbrella, cash) can help with wordiness and just stupidly rough DOM signatures, but they don't shift the paradigm. Edit: If you want a "ready to use" widget hierarchy that simulates desktop paradigms, interrogate llms about modern ExtJS alikes. It was the closest thing, afaik.
