Lovely Golang! I like this feature in Go which you can return multiple values from your functions 🙂
Look at the below function definition and you can see that you can have many outputs from one function:
func myFunction() (output1 type, output2 type, output3 type) {
return output1, output2, output3
}A simple code example:
package main
import (
"errors"
"fmt"
"log"
)
func greeting(name string) (msg string, err error) {
if name == "" {
err := errors.New("the name input is empty")
return msg, err
}
msg = fmt.Sprint("Hello ", name, "!")
return msg, err
}
func main() {
g, err := greeting("morteza")
if err != nil {
log.Fatal(err)
}
fmt.Println(g)
}
