The Pure Functional Web

" summary

Compares Elm’s single-source-of-truth Elm architecture with PureScript’s closer-to-Haskell approach, emphasizes type classes (semiring for numeric genericity) and visible monads, and shows a PureScript reimplementation of a virtual DOM (PureScript virtual DOM) plus a small UI framework ecosystem (Halogen, Pux, Thermite). Builds and compiles a working increment/decrement counter app wired to a signal stream, demos color-changing style, and notes tooling and editor pain but the PureScript end-to-end demo runs.
