The official repository for the Scala 3 & FP Essentials course

Powered by Rock the JVM!

This repository contains the code we wrote during Rock the JVM's Scala 3 & FP Essentials course. Unless explicitly mentioned, the code in this repository is exactly what was caught on camera.

Installation

How to install:

• either clone the repo or download as zip
• open with IntelliJ as it's a simple IDEA project

Getting Started

Run this command in a git terminal to reset the code in its starting/clean state:

git checkout start
