Hjavascript defines a haskell abstract syntax and pretty printer for a subset of javascript. however, a significant difference from javascript is that hjavascript is typed, even on the abstract syntax level using gadts. the subset of javascript that is supported is those parts that lend themself to typing (i.e. no prototyping of classes). if you don't know what haskell and all these concepts are, you can just ignore this package.

this package provides a library for the haskell programming language. see http://www.haskell.org/ for more information on haskell.
