multiple return values _ golang

Go has built-in support for multiple return values. This feature is used often in idiomatic Go, for example to return both result and error values from a function

package main

import (
    "fmt"
)

func vals() (int, int) {
    return 3, 7
}

func main() {
    a, b := vals()
    fmt.Println(a)
    fmt.Println(b)

    _, c := vals()
    fmt.Println(c)
}

3
