I&#x27;m using PureScript because it is purely functional and has a powerful type system like Haskell, but compiles to JS with easy FFI and I can use it with webpack. I&#x27;m writing both a backend API server and frontend app with it. It&#x27;s been amazingly productive and a godsend for writing type-safe JS.<p>On the front-end, it has purescript-pux, which is pretty much a port of the Elm architecture. The language&#x2F;community is really shaping up.
