That property could be important Much nicer than dealing with the minutiae of parallelism threads, semaphores, locks, barriers, etc. But they are rooted in a long history, reaching back to Hoare's CSP in and even Dijkstra's guarded commands Erlang is closer to the original CSP, where you communicate to a process by name rather than over a channel.

We can hang around a little, and on the way show that both main and the launched goroutine are running. What is a goroutine? It's an independently executing function, launched by a go statement. It's practical to have thousands, even hundreds of thousands of goroutines. Instead, goroutines are multiplexed dynamically onto threads as needed to keep all the goroutines running.

Our boring examples cheated: A sender and receiver must both be ready to play their part in the communication. Otherwise we wait until they are. Buffered channels can be important for some problems but they are more subtle to reason about. Our boring function returns a channel that lets us communicate with the boring service it provides.

These programs make Joe and Ann count in lockstep. We can instead use a fan-in function to let whosoever is ready talk. The select statement provides another way to handle multiple channels.

It's like a switch, but each case is a communication: After function returns a channel that blocks for the specified duration. After the interval, the channel delivers the current time, once.
