Sharing variables across goroutines without explicit synchronization. Avoidance: Use the -race flag ( go test -race . ) and prefer communication via channels over shared memory.

If you are looking for free introductory content, the author provides several official resources: 100 Go Mistakes and How to Avoid Them - Amazon.in

Not using go test -race to detect data races. Fix: run race detector in CI.

Re-implementing features present in stdlib. Fix: check packages (time, net/http, io, bufio, etc.) first.

Invest in the legal version, print a copy for your desk, and start eliminating mistakes one by one. Your future self, debugging at 2 AM, will thank you.

The book provides practical advice and examples to help you write better Go code. By learning from common mistakes, you'll improve your skills and become a more effective Go developer.

If you’d like, I can:

: Many developers struggle with structure, such as misusing init functions which can complicate testing, or interface pollution where interfaces are defined prematurely before a clear need exists.

: Subtle bugs involving slices, maps, and string allocations. Concurrency : Data races, deadlocks, and goroutine leaks.

Not adding context to errors (where/why). Fix: wrap with context before returning.

Returning a concrete type that is nil inside an error interface.
