Get up to speed on Scala–the JVM, JavaScript, and natively compiled language that offers all the benefits of functional programming, a modern object model, and an advanced type system. Packed with code examples, this comprehensive book shows you how to be productive with the language and ecosystem right away. You’ll learn why Scala is ideal for building today’s highly scalable, data-centric applications while maximizing developer productivity.

While Java remains popular and Kotlin has become popular, Scala hasn’t been sitting still. This third edition covers the new features in Scala 3 with updates throughout the book. Programming Scala is ideal for beginning to advanced developers who want a complete understanding of Scala’s design philosophy and features with a thoroughly practical focus.

  • Program faster with Scala’s succinct and flexible syntax
  • Dive into basic and advanced functional programming techniques
  • Build killer big data and distributed apps using Scala’s functional combinators and tools like Spark and Akka
  • Create concise solutions to challenging design problems with the sophisticated type system, mixin composition with traits, pattern matching, and more
