Functional Programming in Kotlin with Arrow (English)

Detailed workshop description

Functional programming has been on the rise, given its advantages in code readability and maintenance. In this workshop, we’ll look at concepts from functional programming that are directly applicable to Kotlin code. We’ll use Arrow as a supporting library, which includes many useful types and extensions to make a functional style even more pleasant.

Key take-aways from this Kotlin workshop:

How to model your domain using hierarchies of data classes
The importance of immutability and how it impacts your code style
How to approach validation in a more composable way
Keeping track of contexts and side effects
Making asynchronous code more resilient with Arrow Fx

How to get the most out of this workshop

We will keep you posted on what you need for this workshop and how you should be prepared.
