Mark Lewis Introduction to the Art of Programming Using Scala was the first textbook to use Scala for introductory CS courses. Scala continues to gain significance among professional developers, and a new edition of this popular textbook is needed to update the book from Scala 2.9 to Scala 2.12. The second edition will be divided into two textbooks. The first volume is designed for CS1 courses and will focus on programming and problem-solving using Scala. The book will be significantly updated throughout to bring the code up-to-date for Scala 2.11 and 2.12.
