Create Empty Map in Golang

Create Empty Map

To create an empty Map in Go language, we can either use make() function with map type specified or use map initializer with no key:value pairs given.

Create an empty Map: string->string using make() function with the following syntax.

make(map[string]string)

Create an empty Map: string->string using Map initializer with the following syntax.

make(map[string]string)

Examples

Empty Map using make()

In the following example, we create an empty Map with key of type string and value of type string, using make() function.

Example.go

package main

import "fmt"

func main() {
	x := make(map[string]string)
	fmt.Println(x)
}

Output

map[]

Empty Map using Map Initializer

In the following example, we create an empty Map with key of type string and value of type string, using Map initializer. Pass no key:value pairs in the curly braces.

Example.go

package main

import "fmt"

func main() {
	x := map[string]string{}
	fmt.Println(x)
}

Output

map[]

In this Golang Tutorial, we learned how to create an empty Map in Go language, with the syntax and example programs.
