That's a perfect introduction to Scala basics and common features. This book introduces a vast number of examples (well, as stated in its title) and exercises which allow to keep your understanding of what is going on. Although end chapters were kind of hardcore for me, but that is probably because of lack of experience in that domain and in FP in general. I would only recommend reading Scala User Guide on official site before starting this book as that will help you to understand it much more clearly without distracting on all of new syntactical elements.
Los primeros capítulos son muy buenos. El resto se centra más en cuestiones vinculadas a la programación funcional. Por lo tanto hay que tener un poco más de conocimiento para apreciarlo.
