Can elements be added to a map when passing it to a function?

In Go, when passing a map to a function, a reference to the original object is passed, not a copy. This means that inside the function, you can add, modify, or delete elements from the map, and these changes will be visible outside the function.

Example:

func addElement(m map[string]int, key string, value int) {
    m[key] = value
}

func main() {
    myMap := make(map[string]int)
    addElement(myMap, "one", 1)
    fmt.Println(myMap) // Will output: map[one:1]
}

Thus, the map can be modified inside the function without needing to return it.
