A common way to use timer in the go language

This example summarizes the common ways to use timer in the go language. Share with you for your reference. The specific analysis is as follows:

The following three pieces of code (A,b,C) are the go language code that executes the specified function after 5 minutes:

// (A)

time.AfterFunc(5 * time.Minute, func() {

    fmt.Printf("expired")

}

// (B) create a Timer object

timer := time.NewTimer(5 * time.Minute)

<-timer.C

fmt.Printf("expired")

// (C) time.After() returns timer.C internally

<-time.After(5 * time.Minute)

fmt.Printf("expired")
