In this episode of Fragmented, we wrap up another 2 part series. We dive into the details of the Arrow library with this one. Arrow is a library in Kotlin that helps bring many of the functional paradigms of programming to your daily development. We talk to the team about how it all started, the history of the library, why we even need arrow, how Arrow is structured, some of the pitfalls, and in the end some resources on getting us started with Arrow.

In this episode of Fragmented, we kick off another 2 part series. This time it's with the Kotlin Arrow team! In the first part, we talk to Jorge, Raul and Paco about Functional programming in general, some core FP concepts, do we already use functional programming today, what are pure functions, do I need to know complicated math to do FP, Immutability, Referential transparency and so much more. These are all pretty daunting words, but the Arrow team break it down and make it really simple for us to understand.
