Scala 3 — Book



This chapter provides a high-level introduction to functional programming in Scala. The topics covered are:

  • What is functional programming?
  • Immutable values
  • Pure functions
  • Functions are values
  • Functional error handling

As mentioned, functional programming is a big topic, so all we can do in this book is to touch on these introductory concepts. See the Reference documentation for more details.
