How to check if an item exists in Slice in Golang?

To determine if a specified item is present in a slice iterate slice item and check using if condition.


package main

import (

func main() {
	var strSlice = []string{"India", "Canada", "Japan", "Germany", "Italy"}
	fmt.Println(itemExists(strSlice, "Canada"))
	fmt.Println(itemExists(strSlice, "Africa"))

func itemExists(slice interface{}, item interface{}) bool {
	s := reflect.ValueOf(slice)

	if s.Kind() != reflect.Slice {
		panic("Invalid data-type")

	for i := 0; i < s.Len(); i++ {
		if s.Index(i).Interface() == item {
			return true

	return false
