TL;DR; Any Go developer, beginner or expert, would do well to read this book. Probably more than once.

Read or watch my full review. Or here’s a short snippet:

Ultimately, the book is 100 short sections, each of which describes a Go mistake, followed by an explanation, and how to avoid or mitigate the mistake. These sections are grouped by topic into chapters, and some include a conceptual introduction to the topic.
