How to Iterate Over a Map in Go (And Why Order Is Random)

Iterate over a Go map using a range loop, but expect random order as Go intentionally shuffles traversal to prevent reliance on sequence.

Use a for key, value := range m loop to iterate, but be aware that Go intentionally randomizes the order of map traversal to prevent code from relying on a specific sequence.

m := map[string]int{"a": 1, "b": 2, "c": 3}
for k, v := range m {
    fmt.Println(k, v)
}

The randomization ensures that your code remains robust and doesn't break if the underlying map implementation changes or if the map is modified concurrently.
