Sprinkles of Functional Programming
summary
Argues that small doses of functional style speed Rails tasks that are about transforming data, not modeling behavior, by replacing many service classes with a single data pipeline and keeping IO separate from pure functions. Uses Ruby features like then plus CSV and Excel parsing to build an importer that ships and onboards clients. Result: roughly fourfold less code, one public API instead of eight, and development time drops from about one day to about one hour.
