2. Navigate to the directory.
3. Create the timeout.go file with the following content:

        package main        import (          "fmt"          "time"        )        func main() {          to := time.After(3 * time.Second)          list := make([]string, 0)          done := make(chan bool, 1)          fmt.Println("Starting to insert items")          go func() {            defer fmt.Println("Exiting goroutine")            for {              select {                case <-to:                  fmt.Println("The time is up")                  done <- true                  return                default:                  list = append(list, time.Now().String())              }            }          }()          <-done          fmt.Printf("Managed to insert %d items\n", len(list))        }

4. Execute the code by running go run timeout.go in the main Terminal.
5. You will see the following output:
