All of these discussions seems to forget that React hooks is two different things combined: (1) it's a new magic way of having stateful components and (2) it's a new set of APIs. I don't quite see why they _have_ to be so cou

I love seeing more Ruby implementations! Looking forward to seeing how it will progress. Are there any details on how it’s implemented? How does it execute Ruby? Does it have its own bytecode? Does it compile to machine code on the fly? Wha

This paper is very light on details. It defines "RInK architecture" as something which uses stateless application servers w/ key-value store as backend (Redis/Memcached). Section 3 then shows that it's faster to use

But why does Hooks need to be implemented on top of functions and not classes? The way I see it is that Hooks today implements two distinct things: (1) a composable way to handle lifecycle and (2) a custom way to store state. Why can't
