Functional Programming in Kotlin for AndroidDevs

on YouTube ↗34m

" summary

Starts from math (domain/codomain and referential transparency) and shows concrete Kotlin code: mapping/reduce examples, a polymorphic function composition implementation using generics, an extension + infix-based API to chain functions, and a curried implementation to handle multi-argument cases. Demonstrates how Arrow’s Option and Either model nullable and error flows, argues a 100% functional Android app is impractical but extracting computations to pure functions works, and recommends gradual adoption and two books for next steps.
