Scala 3 New Features

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.

This course will show you just the new features in Scala 3, so you can upgrade your skills as fast as possible.

Skills you'll get after taking this course

• understand how the Scala language and runtime changed
• use the new abstractions in Scala 3
• use new simplified syntax in Scala 3
• maintain your code style in Scala 3 (if conservative)
• change your code style in Scala 3 to braceless and indentation (if adventurous)
• cut the removed features of Scala 2 out of your code before upgrading to Scala 3
• organize your code better with the new importing features
• interoperate better with Java

How this course helps you

• it walks you through each important change in the language so you know what to do at work
• it gives you examples that are relevant for real Scala projects
• it gives you just the tips you need, without going through basics all over again
• it organizes the changes that will likely affect you, so that you won't spend time asking "how is this relevant?"
• it selects and sequences out the topics so they click in your head

The main value of the course is that it saves you time.

This course is compact and will give you everything you need in just 4 hours. By comparison, I've spent thousands of hours learning everything there is to know about Scala here for Rock the JVM, and I've stalked the Scala 3 repo and studied the impact of Scala 3 changes for hundreds of hours, so that you get the same insight in an afternoon instead of a month.

Short as it is, the course packs a punch - we write 1000+ lines of code in this course! If you know my style, you know I like to get straight to the point and I won't waste a minute of your time.

Time is your most valuable resource. My pledge to you is that in this course, you'll spend it well.
