Kotlin & Functional Programming: pick the best, skip the rest

on YouTube ↗44m

" summary

Argues that specific FP choices matter: Kotlin scope functions tame mutable APIs, Result and Either model errors but Either suits domain-level error handling, and blind use of monads turns code into a “container terminal.” Demonstrates Arrow (effects, monad comprehensions, optics) and Kotlin features (context receivers, bind) and shows they actually simplify flatMap nesting and nullable plumbing. Recommends selective use (avoid wrapping DB layers, prefer Either for recoverable errors); the Arrow rewrite is presented as a working bridge.
