100 Go Mistakes and How to Avoid Them

100 Go Mistakes and How to Avoid Them takes a refreshingly practical approach to learning Go: instead of teaching the language in the abstract, it focuses on the errors developers most often make and shows how to avoid them. Teiva Harsanyi organizes the material around 100 specific mistakes, making the book useful both as a structured read and as a reference you can return to when a particular problem shows up in your code.

A field guide to common Go pitfalls

The book covers the everyday trouble spots that matter in real projects: code and project organization, data types, control structures, strings, functions and methods, error handling, concurrency, testing, standard-library usage, and optimization. That scope makes it especially helpful for developers who already know Go syntax but want to write cleaner, more idiomatic, and more dependable code.

Clear explanations, focused fixes

Each mistake is treated as a small lesson in its own right. The format is designed to answer two practical questions: why is this a problem? and what should I do instead? That makes the book well suited to debugging habits, sharpening day-to-day coding decisions, and reducing the kinds of subtle issues that can creep into otherwise working Go programs.

Who this book is for

This is a strong fit for Go developers who have moved beyond the basics and want to deepen their judgment. It also works well as a desk-side reference for engineers who prefer learning from concrete examples rather than broad theory.

If you want a book that speaks directly to the practical realities of writing Go code, this one earns its place on the shelf. 📘
