The Fun of Functional Programming Panel
summary
Panel argues that functional programming makes code understandable by turning components into pure functions as equations and using types to encode meaning, with libraries like Scalaz and Cats giving proven abstractions and patterns like traverse to replace loops. Tradeoffs surface: megamorphic call cost and heap churn and GC pain on the JVM, tricky IDE/debugging, and steep initial learning curve. Concrete wins include safer resource handling, easier maintenance, and real adoption through Spark/Scala at companies and data teams.
