“The book is written in an accessible style, with numerous examples, and is suitable for a wide range of audiences from novices, just starting to learn how to handle a programming language, to experts trying to get to grips with Scala. The continuous parallel between Scala and Java is used to highlight an interesting angle in both languages, so, technically, the book can be used as a guide to both Java and Scala.” (Irina Ioana Mohorianu, zbMATH 1382.68005, 2018)
