How to add an Item to a Set in Go - Step by Step Examples

How to add an Item to a Set in Go ?

To add an item to a Set in Go, you can use the built-in map data structure.

In this example,

We declare a map variable named mySet with keys of type string and values of type bool.
We assign true as the value for the key representing the item we want to add.

package main

import "fmt"

func main() {
    mySet := make(map[string]bool)
    mySet["item1"] = true
    fmt.Println(mySet)
}

map[item1:true]

In this example,

We declare a map variable named numberSet with keys of type int and values of type bool.
We assign true as the value for the key representing the integer we want to add.

package main

import "fmt"

func main() {
    numberSet := make(map[int]bool)
    numberSet[123] = true
    fmt.Println(numberSet)
}

map[123:true]
