Overview
This course covers advanced functional programming concepts using Cats, a library which provides abstractions for functional programming in the Scala programming language.
In this introductory course, we’ll review the primary concepts used in functional programming including monoids, semigroups, functors, and monads, and, while using Cats, we’ll learn about the main type classes and datatypes.
Prerequisites
One year of experience in Scala or any other Functional Programming Programming language.
What you'll learn
Key Functional Programming concepts:
- Introduction to Functional Programming in Scala with Cats
- Pure Functions
