Programming in Scala (A comprehensive step-by-step guide) - Lex Spoon, Bill Venners, Frank Sommers

This book is the authoritative tutorial on the Scala programming language, co-written by the language's designer, Martin Odersky. This fifth edition is a major rewrite of the entire book, adding new material to cover the many changes in Scala 3.0. In fact we have added so much new material that we split the book into two volumes. This volume is a tutorial of Scala and functional programming. The second volume, which will be released as a PrePrint™ soon, is a deep dive into advanced aspects of Scala 3. The changes and new features covered in this version of this PrePrint™ include: Quiet (indentation-sensitive) control syntax Intersection and union types Enums and Algebraic Data Types (ADTs) Context parameters and given instances (the new approach to implicit parameters) Trait parameters Creator applications New vararg pattern syntax Extension methods
