about the technology Functional programming (FP) is a style of software development emphasizing functions that don''t depend on program state.

Functional code is easier to test and reuse, simpler to parallelize, and less prone to bugs than other code. Scala is a popular JVM language that offers strong support for FP. Its familiar syntax and transparent interoperability with Java make Scala a great place to start learning FP.

about the book Functional Programming in Scala, Second Edition teaches you functional programming from first principles using the powerful Scala language.

You''ll develop the unique skills you need to start thinking functionally through hands-on exercises and coding challenges. New to the revised second edition, each exercise comes with extensive annotations to help you understand functional programming in-depth. You''ll even learn how to build your own Scala functional library that''s perfectly adapted to your needs.

You''ll soon be writing Scala code that''s easier to read, easier to reuse, better for concurrency, and less prone to bugs and errors.

RETAIL SELLING POINTS 

• Recognize and write purely functional code 
• Work with errors without using exceptions 
• Work with state and concurrency 
• Interact with functional structures that define common behaviours 
• Write code that performs I/O without sacrificing functional programming 

AUDIENCE 

For programmers experienced in Java or Scala No prior knowledge of functional programming required.
