Benefits of Functional Programming Beyond map/filter/reduce
summary
The talk explains functional programming benefits beyond common Java 8 use of lambdas, streams and map/filter/reduce, showing how purely functional techniques enable safe parallelism and type-level guarantees like preventing wrong-thread calls. It demonstrates applying these ideas across functional languages on different platforms, mentioning Frege (JVM), Elm and Purescript (web), and Haskell and Idris (native).
