Learn Functional Programming!

Functional programming can feel like an academic topic: category theory and monads and monoids, oh my! But it can be pragmatic. You can build off the knowledge you already have to apply this paradigm and build safer, more reliable applications.

Functional Programming in Kotlin by Tutorials is here to help by showing you hands-on methods to apply pure functions, immutability and composition to simplify your complex logic!
