In the land of gophers (for ages 3 and up)
summary
A playful introduction to Go concurrency explaining concrete details: the go keyword launches a goroutine, goroutine stacks grow on demand (examples mention sizes up to 1 GB), and the runtime multiplexes many goroutines onto a few OS threads. It covers Go communication primitives and patterns: channels (including buffered channels created with make(chan T, 10)), close to signal no more sends, select with default to avoid blocking, and sync.WaitGroup coordination using Add(n)/Done()/Wait() with a 5-worker example.
