Programming Scala

Get up to speed on Scala, the JVM language that offers all the benefits of

a modern object model, functional programming, 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,

and explains why Scala is ideal for today's highly scalable, data-centric

applications that support concurrency and distribution.

This second edition covers recent language features, with new chapters

on pattern matching, comprehensions, and advanced functional

programming. You’ll also learn about Scala’s command-line tools, third-

party tools, libraries, and language-aware plugins for editors and IDEs. This

book is ideal for beginning and advanced Scala developers alike.
