Etudes for Erlang: Companion exercises for Introducing Erlang

Erlang is an important programming language especially in light of its functional paradigm, excellent handling of concurrency, ability to deal with distributed and multi-core platforms, reliability and fault-tolerance. It is also a difficult language with an unconventional (Prolog-like) syntax, lack of object orientation, and importantly the nonexistence of variables.

In this book, you will find descriptions of programs that you can compose (write) in Erlang. The programs will usually be short, and each one has been designed to provide practice material for a particular Erlang programming concept. These programs have not been designed to be of considerable difficulty, though they may ask you to stretch a bit beyond the immediate material and examples that you find in the book Introducing Erlang.
