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.
Iterating over a Go map is like grabbing items from a bag where the order you pull them out is random every time. This design prevents your code from accidentally depending on a specific sequence, which could break if the map's internal structure changes. If you need a specific order, you must sort the keys yourself before iterating.
