jq is a very high-level lexically scoped functional programming language in which every JavaScript Object Notation (JSON) value is a constant. jq supports backtracking and managing indefinitely long streams of JSON data. It is related to two programming languages—Icon and Haskell. The language supports a namespace-based module system and has some support for closures. functions and functional expressions can be used as parameters of other functions.
The original implementation of jq was in Haskell[3] before being quickly ported to C.
