Why This Simple Go Program Deadlocks: The Hidden Goroutine Trap

The article explains why a seemingly straightforward Go program that creates an unbuffered channel, launches a goroutine to print a received value, and then sends a value deadlocks, analyzes the evaluation order of go statements, and shows how to fix the issue by moving the receive into a separate goroutine.
