PureScript (Maybe This Time We Get JavaScript Right)

on YouTube ↗45m

" summary

Builds a compact game engine for tiny browser ads, first trying TypeScript + RxJS then switching to PureScript and Bacon to meet strict size limits; PureScript compiles to concise JS and the runtime is tiny so the deliverable stays under constraints. Uses FFI for DOM rendering, a signal-style reactive loop ported from Elm, property tests with QuickCheck, and a working prototype that ships in production. PureScript generates ≈10KB runtime swapped RxJS for Bacon to save ~30–40KB
