The Official Go Tutorial Has a DANGEROUS Bug

🚨 The Official Go Tutorial Has a DANGEROUS Bug | Go Gin Race Condition Fix https://go.dev/doc/tutorial/web-service-gin I discovered a critical race condition bug in the official Go website's Gin tutorial that's being copied by thousands of developers! 😱. This “simple” REST API example causes data loss when multiple goroutines access shared data concurrently, and most people don’t even realize it’s happening. 💻 In this video I show: - The exact bug in the official Go Gin example - How to reproduce the data corruption - Step-by-step fix using sync.RWMutex - Before & after testing results This isn't just about one tutorial - it's about understanding why concurrent programming in Go requires careful attention to thread safety, even in "simple" examples. 🔗 Source code https://github.com/patni1992/go-gin-bug
