Easy way to get the keys in a map in alphabetical order

Question

In Go, what\'s the easiest way to get the keys in a map sorted alphabetically? This is the shortest way I can do it:

package main

import \"container/vector\"
im         


        

Answer 1

That would be most elegant method:

package main

import (
    "fmt"
    "sort"
)

func main() {
    m := map[string]string{"b": "15", "z": "123123", "x": "sdf", "a": "12"}
    keys := make([]string, 0, len(m))
    for key := range m {
        keys = append(keys, key)
    }
    sort.Strings(keys)
    fmt.Println(keys)
}
