## What it is
The source code and community site for the book '100 Go Mistakes and How to Avoid Them', cataloging common Go programming pitfalls with explanations and fixes. It serves as a free online reference of Go best practices covering code organization, generics, concurrency, and more.

## Use cases

- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
