Appendix A: Scala 3 Syntax Notes for This Book

Coming soon

This appendix is an outline. The full draft ships in a follow-up PR.

What this appendix will cover

A concise reference for the Scala 3 features this book relies on, aimed at readers coming from Scala 2, Java, or another strongly-typed language.

Topics:

• Indentation-based syntax (and when braces are still handy).
• @main annotated entry points.
• given / using for contextual parameters.
• Enum types and pattern matching.
• Extension methods.
• Why new is almost never needed.
