Goroutines are not coroutines! I thought it was a nice pun! It's not! Russ walks us over the concept of coroutines in other languages and then implements them in Go using goroutines. Gotta read more thoroughly. I don't really see why we need them. P. S. Loving how coroutine is shortened to coro. It's how the Francophones shorten laboratorie or whatever to just labo. Adolescent becomes ado. Cool French style!
