Gist of Go: Race conditions

Race conditions occur when unpredictable operation order leads to incorrect system state, different from data races which involve unsafe concurrent data access. The article demonstrates how to prevent race conditions using mutexes to protect entire operation sequences, compare-and-set operations for atomic updates, and shared-nothing architecture with channels. Key techniques include making operations idempotent and atomic, using TryLock for non-blocking access, and leveraging Go's sync.Locker interface for flexible locking mechanisms.
