Lately, I've been working on a new library called purescript-sdom. It is an attempt to build a UI library in 100% PureScript without using the virtual DOM. I'll give an overview of the motivation behind the library, and the way in which it was implemented.
Once we were over the infamous Haskell learning-curve, we began looking for functional programming, immutability, and types everywhere! Given that one-third of our code runs in the browser (via Angular v1 — for now!), it is only a matter of time before we make the switch to typed-FP for front-end development as well.
