Justin Woo is a self described Purescript evangelist and enthusiast. We talk about purescript vs elm and working with expressive type systems.  Justin also had some great metaphors about phantom types and masking tape as well as avacados and testing.   Contact Justin: twitter github website Show notes: Purescript purescript training videos     My team at Tenable is hiring.  We are a distributed team of scala developers working on static analysis of docker containers (among other things).
