"An experienced programmer can learn a great deal of Scala from this book. Clearly, this book is meant and best used for self-study, but it could also be used as a textbook at the upper undergraduate or graduate level."
--Edgar R. Chavez, Computing Reviews
"...the final consideration is that Programming Scala is a good work and it's one of the best ways and one of the best books to enter in the wonderful Scala world."
--Roberto Bentivoglio, JUG Lugano
