Functional Programming Kata with Groovy



Scott Hickey works through a solution to the Bank OCR kata, using Groovy and functional programming techniques. Hickey uses pure functions that are small and easy to test. The code uses recursion plus Groovy methods that support functional programming such as take, drop, first, tail, find, findAll, collect, collectMany, and transpose.


Scott Hickey is a Principal Enterprise Architect.
