The article explains Go's memory model and why data races occur when sharing variables between goroutines without synchronization. It demonstrates how a seemingly correct program can fail due to compiler and CPU optimizations, and introduces the Go race detector as a tool to catch such issues.
Background
Go's concurrency model based on goroutines and channels is widely used, but understanding its memory model is critical for writing correct concurrent programs. The race detector has been part of Go since version 1.1.
