Overview
It is possible to create a slice or array of string data type in Golang as well. In fact, a slice or array can be created of any data type in Go. This tutorial contains simple examples to create a slice or array of string data type in golang.
Just to add here that in golang array is of fixed size and slice can have variable size. More details here

Slice of String
package main
import "fmt"
func main() {
//First Way
var string_first []string
string_first = append(string_first, "abc")
string_first = append(string_first, "def")
string_first = append(string_first, "ghi")
fmt.Println("Output for First slice of string")
for _, c := range string_first {
fmt.Println(c)
}
//Second Way
string_second := make([]string, 3)
string_second[0] = "ghi"
string_second[1] = "def"
string_second[2] = "abc"
fmt.Println("\nOutput for Second slice of string")
for _, c := range string_second {
fmt.Println(c)
}
}
Output
Output for First slice of string
abc
def
ghi
Output for Second slice of string
ghi
def
abc
We have two ways of creating a slice of strings. The first way is
var string_first []string
string_first = append(string_first, "abc")
string_first = append(string_first, "def")
string_first = append(string_first, "ghi")
In the second way, we use make command to create a slice of strings
string_second := make([]string, 3)
string_second[0] = "ghi"
string_second[1] = "def"
string_second[2] = "abc"
Either way works. This is how we can create a slice of strings
Array of Strings
package main
import "fmt"
func main() {
var string_first [3]string
string_first[0] = "abc"
string_first[1] = "def"
string_first[2] = "ghi"
fmt.Println("Output for First Array of string")
for _, c := range string_first {
fmt.Println(c)
}
string_second := [3]string{
"ghi",
"def",
"abc",
}
fmt.Println("\nOutput for Second Array of string")
for _, c := range string_second {
fmt.Println(c)
}
}
Output
Output for First Array of string
abc
def
ghi
Output for Second Array of string
ghi
def
abc
We have two ways of creating an array. The first way is
var string_first [3]string
string_first[0] = "abc"
string_first[1] = "def"
string_first[2] = "ghi"
In second way we directly initialize the array with some strings
string_second := [3]string{
"ghi",
"def",
"abc",
}
