I'd like to have a feature of Golang which is functions returning multiple values in JavaScript. Here's the code.

package main

import (
    "fmt"
)

func main() {
    str, bl, num := variadicFn("India")
    fmt.Println(str, bl, num)   // "Hello, India" true, 100
}

func variadicFn(what string) (string, bool, int) {
    return "Hello, " + what, true, 100
}

Actually, with the latest JS features that's easy to emulate in JS using array/object desructuring syntax: developer.mozilla.org/en-US/docs/Web/JavaScript/R…

Nishant Agrwal but it's only one value that is returned i.e, an Object.

const fn = () => (
  { first: 1, second: 2 }
)

let { first, second } = fn() // returns object containing multiple values which is in this case first & second.

func fn() (string, bool, int) {
    return "Hello, India!!", true, 100
}

first, second, third := fn() // returns multiple values and not an object or array containing multiple values.
