Learn Scala 3 new features without learning the language all over again. A short course for Scala 2 developers.

Learn Scala 3 new features now.

If you're reading this, you're a Scala developer. Unless you've been like Tom Hanks in Cast Away, you know Scala just took a major leap: Scala 3 is a revolutionary step in the evolution of the language and there are lots of changes to simplify our lives as developers. LOTS of them.

Geting yourself familiar with Scala 3 new features can be a challenge, since there are so many changes in the language, a million places on the web describing bits and pieces, and your time is limited. If you're like me, you don't want to spend dozens of hours scouring the web or learning the upgraded Scala 3 Essentials and Advanced courses here on Rock the JVM all over again.

Skills you'll get after taking this course

understand how the Scala language and runtime changed
use the new abstractions in Scala 3
