Slice of Map in Go (Golang)

Overview

It is possible to create a slice of map data type in Golang as well. In fact, a slice can be created of any data type in Go. Below is a simple example to create a slice of map

Program

package main

import "fmt"

func main() {
	maps := make([]map[string]string, 3)

	map1 := make(map[string]string)
	map1["1"] = "a"

	map2 := make(map[string]string)
	map2["2"] = "b"

	map3 := make(map[string]string)
	map3["3"] = "c"

	maps[0] = map1
	maps[1] = map2
	maps[2] = map3

	for _, m := range maps {
		fmt.Println(m)
	}
}

Output

map[1:a]
map[2:b]
map[3:c]

In the above program, we created three maps of type map[string]string

map1 := make(map[string]string)
map1["1"] = "a"

map2 := make(map[string]string)
map2["2"] = "b"

map3 := make(map[string]string)
map3["3"] = "c"

We also created a slice of map data type like this

maps := make([]map[string]string, 3)

This is how we can create a slice of map
