Golang : How to iterate a slice without using for loop?

A very simple example on how to iterate a slice of integers without using a for loop and use recursive method instead.

 package main

 import (
  "fmt"
 )

 func main() {
  integerSlice := []int{0, 1, 2, 3, 4}
  loopIntegerSlice(integerSlice, 0)
 }

 func loopIntegerSlice(numbers []int, index int) int {

  // iterate a slice and print out the elements without using a for loop

  if index == len(numbers) {
 return numbers[index-1] // break here
  } else {
 n := numbers[index]
 fmt.Println(n)
 return loopIntegerSlice(numbers, index+1) // use recursive method
  }
 }

Output:

0

1

2

3
