Why does Go's map iteration order vary when printing?

Question

package main

import \"fmt\"

func main(){
    sample := map[string]string{
    \"key1\":\"value1\",
    \"key2\":\"value2\",
    \"key3\":\"value3\",
    }
    for          


        

Answer 1

You cannot rely on the order in which you will get the keys. The language spec says "A map is an unordered group of elements", and later "The iteration order over maps is not specified and is not guaranteed to be the same from one iteration to the next."
