'''PureScript''' is a [[strict evaluation|strict]], [[purely functional programming|purely functional]] [[programming language]] inspired by [[Haskell (programming language)|Haskell]] which [[Source-to-source compiler|compiles]] to readable [[JavaScript]] with a simple [[foreign function interface]] and no runtime dependency.<ref>{{cite web|url=http://www.purescript.org/|title=PureScript|website=Purescript.org|accessdate=20 December 2017}}</ref><ref>{{cite web|url=https://github.com/purescript/purescript|title=purescript: A strongly-typed language that compiles to Javascript|date=20 December 2017|accessdate=20 December 2017|publisher=[[GitHub]]}}</ref><ref>{{cite web|url=https://www.youtube.com/watch?v=LqYfdmb0eUU|title=Learn Functional Programming with PureScript|date=21 May 2015|publisher=[[YouTube]]}}</ref>
