Go Brain Teasers

Exercise Your Mind

by Miki Tebeka

This book contains 25 simple Go programs and will challenge your understanding of Go. The Go programming language is a simple one, but like all other languages it has its quirks. This book uses these quirks as a teaching opportunity. By understanding the gaps in your knowledge, you’ll become better at what you do. These teasers will help you avoid mistakes. Some of the teasers are from my own experience shipping bugs to production, and some from others doing the same. Teasers are fun! We geeks love puzzles and solving them. You can use these teasers to impress your co-workers.


This work was written and produced entirely by the author. We are proud to be distributing it.

At the beginning of each chapter, I’ll show you a short Go program and will ask you to guess the output. The possible answers can be:

  • Won’t compile
  • Panic
  • Deadlock
  • Some output (e.g. `[1 2 3]`)

There’s a lot of research showing that people who make mistakes during the learning process learn better than people who don’t. If you use this approach at work when fixing bugs, you’ll find you enjoy bug hunting more and become a better developer after each bug you fix.

Many of these brain teasers are from quizzes I gave at conferences and meetups. I’ve found that people highly enjoy them and they tend to liven the room.

Before moving on to the answer and the explanation, go ahead and guess the output. After guessing the output I encourage you to run the code and see the output yourself, only then proceed to read the solution and the explantation. I’ve been teaching programming for many years and found this course of action to be highly effective.

What You Need

This book assumes you know Go at some level and have experience programming with it.

NOTE: I’m using Go version 1.14.1 to run the code, the output might change in future versions.

You will need a working Go environment, you can download it from golang.org. You will probably want a good IDE for Go, two of the most popular ones are Visual Studio Code and GoLand.
