Leveraging the power of Arrow
summary
Covers how to use the Arrow library for typed functional programming in Kotlin, demonstrating core abstractions like Option, Try, Either, IO, Functor, Applicative, Monad and type classes. Shows setup for Arrow, builds a simple Kotlin app using Arrow with examples, and finishes with a code walkthrough and demo of an Android MVP app implemented with Arrow.
