Ruby versus the Titans of FP
summary
Compares Ruby to Clojure Haskell and JavaScript by showing concrete implementations not abstractions: implements a higher order map as a proc that delegates to Array#map, builds curried add with closures and uses Ruby’s native curry, implements binary and variadic compose then composes incrementers, and publishes a tiny reductio gem with add compose and map that works. Demonstrations include MapReduce-style composition, notes on ActiveRecord side effects, and promises benchmarks and an IO-style approach as future work.
