Concurrency Patterns in Go

When switching from Python to Go, the most immediate paradigm shift is handling concurrency. While Python relies on asyncio, Go utilizes the power of Channels.

The Generator Pattern

Here is a classic example of a generator in Go. Notice how the channel acts as a synchronization point.

1
func main() {
2
    c := make(chan string)
3
    go boring("boring!", c)
4
    for i := 0; i < 5; i++ {
5
        fmt.Printf("You say: %q\n", <-c)
6
    }
7
    fmt.Println("You're boring; I'm leaving.")
8
}
