Scala

This is a four day Scala course loosely based off Google’s Comprehensive Rust. The course will attempt to cover the full spectrum of Scala 3, from basic syntax to advanced topics like higher-kinded types, effect libraries and tagless final style programs.

Goals

The goals of the course is to get you to a working understanding of advanced Scala. In this course I will assume you don’t know anything about Scala and I hope to:

• Give you a rough understanding of Scala’s advanced features
• Enable you to read and contribute to Scala programs that use these features
• Hopefully convince you that writing software like this is productive, rewarding and all around fun 😹

Non-Goals

Unless you already have experience with other FP languages like Haskell, it is probably going to take more than a few days to completely learn Scala. So some non-goals of this course are:

• Learn about a lot of the OOP side of Scala
• Learn how to use Akka
• Learn about variance (Wikipedia)

Assumptions

This course assumes that you already know how to program. Scala is a statically typed language and there might be some comparative references to Haskell but I will also try to use TypeScript in-case that’s easier.

You don’t have to know functional programming, but it will be the primary paradigm used in this course.
