Go language: Iterate over a slice using range keyword

Example 1: Get the value of slice from index

for i := range vowels {

         fmt.Println(vowels[i])

}

Example 2: Get the index and value of slice

for i, v := range vowels {

         fmt.Printf("index %v, value %v\n", i, v)

}

App.go

package main

import "fmt"

func main() {

 var vowels = []string{"a", "e", "i", "o", "u"}

 for i := range vowels {
  fmt.Println(vowels[i])
 }

 for i, v := range vowels {
  fmt.Printf("index %v, value %v\n", i, v)
 }

}

Output

a
e
i
o
u
index 0, value a
index 1, value e
index 2, value i
index 3, value o
index 4, value u
