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.

</>
Copy
make(map[string]string)

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

</>
Copy
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

</>
Copy
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

</>
Copy
package main

import "fmt"

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

Output

map[]
