1 Creating an Empty Map

We can create an empty map in Go using the make function, which initializes a map with no key-value pairs.

For example,

We start by declaring a variable named emptyMap. This variable will hold our empty map.
We then use the make function to create a new, empty map. In Go, the make function is used to initialize slices, maps, and channels.
The newly created map is now assigned to the emptyMap variable. In this example, the map has string keys and integer values.
We can now perform various operations on this empty map, such as adding key-value pairs, checking for the presence of keys, and retrieving values.

Go Program

package main

import "fmt"

func main() {
    // Declare an empty map
    emptyMap := make(map[string]int)

    // Operations on the empty map
    // ...

    fmt.Println(emptyMap)
}

Output

map[]
