Is golang map in order?

#Map is a built-in type in Go that binds keys and values ​​together. The corresponding value can be obtained by key. (Recommended Learning: Go )

is achieved by the structure of the Golang Map in the structure of HASH, so the order is chaotic.

fruits := map[string] int {
    "oranges": 100,
    "apples": 200,
    "banans": 300,
}

If you want it to be in order, you can transfer the key to the slice, sort the slice, and then output:

// Put the keys in a slice and sort it.
var keys []string
for key := range fruits {
	keys = append(keys, key)
}
sort.Strings(keys)

// Display keys according to the sorted slice.
for _, key := range keys {
	fmt.Printf("%s:%v\n", key, fruits[key])
}
