UI = f(statesⁿ)
“UI is a function of state” is a pretty popular saying in the front-end world. In context (pun intended), that’s typically referring to application or component state. I thought I’d pull that thread a little further and explore all the states that can effect the UI layer…

It would use a library written in rust, called hyper. The idea was to introduce an alternative implementation of HTTP internals that you could ……
