Treasure.map(): Functional Programming in Kotlin

on YouTube ↗29m

" summary

Concrete Kotlin and Java code demonstrates using Either with Arrow to replace try/catch, shows flatMap chains for DB calls and how monad comprehension keeps error handling linear, contrasts that with runCatching hiding OOME, and walks map/filter/fold examples on immutable collections. The talk gives specific tradeoffs: library support, a debugging horror story, performance caveats for immutability, and a step‑by‑step adoption plan rather than academic definitions.
