Kotlin and FP - The Best of Both Worlds

27 January 2021

In our first Kotlin meetup of 2021, Amazon's Katie Levy and Twitter's Shelby Cohen gave an excellent talk on how to combine Kotlin and FP to get 'the best of both worlds'. If you missed their presentation, here are the highlights, sliced and diced.


This talk breaks down the key aspects of what defines functional programming and the key benefits of using FP paradigms. It provides a walkthrough on how to use more FP in your Kotlin code.

As well as covering some basic examples, it also goes into more complex data structures from Arrow, a Functional Programming library for Kotlin. When you walk away from this talk, you should be able to incorporate the tangible examples you have learned into your own Kotlin code.
