Introducing Erlang: Getting Started in Functional Programming

Author(s): Simon St. Laurent

Publisher: O’Reilly Media, Year: 2017

If you’re new to Erlang, its functional style can seem difficult, but with help from this hands-on introduction, you’ll scale the learning curve and discover how enjoyable, powerful, and fun this language can be.

In this updated second edition, author Simon St.Laurent shows you how to write simple Erlang programs by teaching you one skill at a time. You’ll learn about pattern matching, recursion, message passing, process-oriented programming, and establishing pathways for data rather than telling it where to go. By the end of your journey, you’ll understand why Erlang is ideal for concurrency and resilience.
