Overview of this book

Often referred to (incorrectly) as Golang, Go is the high-performance systems language of the future. Mastering Go, Second Edition helps you become a productive expert Go programmer, building and improving on the groundbreaking first edition. Mastering Go, Second Edition shows how to put Go to work on real production systems. For programmers who already know the Go language basics, this book provides examples, patterns, and clear explanations to help you deeply understand Go’s capabilities and apply them in your programming work. The book covers the nuances of Go, with in-depth guides on types and structures, packages, concurrency, network programming, compiler design, optimization, and more. Each chapter ends with exercises and resources to fully embed your new knowledge.

Comparing Go and Erlang concurrency models

Erlang is a very popular concurrent functional programming language that was designed with high availability in mind. Briefly speaking, the main characteristics of Erlang and the Erlang concurrency model are as follows:

  • Erlang is a mature and tested programming language – this also applies to its concurrency model.
  • If you do not like the way Erlang code works, you can always try Elixir, which is based on Erlang and uses the Erlang VM, but its code is more pleasant.
  • Erlang uses asynchronous communication and nothing else.
  • Erlang uses error handling for developing robust concurrent systems.
  • Erlang processes can crash but if that crashing is handled properly, the system can continue working without problems.
  • Just like goroutines, Erlang processes are isolated and there is no shared state between them. The one and only way for Erlang...
