Hopefully quick and light view library (benchmarks TBD :-).
S.js tutorial

vella is currently built on top of S.js by Adam Haile. It is more or less Surplus, but with Hyperscript (and composability cranked to eleven). We may end up forking or replacing S, but the core idea will probably persist. Understanding S is required to get what comes next.
Lexicon: in the S docs, streams are called "signals", and dependent streams are called "computations". I'll use the same terminology for now here to make it easier for you if you're also scouring the S docs. They are mostly push streams AFAIU, but the author descrbes them as hybrid push/pull somewhere in the issues, not sure what he meant.

Warning this is purely a thought experiment and will probably go nowhere.  The language semantics will likely be incongruent and non-rigourous.  Proceed at your own risk.

Philosophy

Javascript always wanted to be a functional language.  But for historical, political and perhaps even sensible reasons, JS's original mission was never truly fulfilled.
But what if, we take JS and start removing things.  We can remove mutation, remove variables, remove classes, remove variadic signatures, remove default arguments and on and on.
What if we go back to ES1 and re-evaluate a future unperturbed by corporate circumstance.

                Deep dive into mithril vnodes
              
          
    In my first explainer of Mithril's source code, I broke down how the hyperscript function worked. It's main task is the creation of virtual DOM nodes (vnodes), the objects which represent DOM elements or parts of the DOM. So how are these objects created?
Vnode functions

This is the function which creates a vnode:
function Vnode(tag, key, attrs, children, text, dom) {
	return {tag: tag, key: key, attrs: attrs, children: children, text: text, dom: dom, domSize: undefined, state: undefined, _state: undefined, events: undefined, instance: undefined, skip: false}
}
This function is assisted in its work by these two helper functions:
