Maps in Go are unordered collections, meaning iteration order is random and non-deterministic. When you need to iterate over a map in a predictable order, the standard approach is to extract the keys into a slice, sort that slice, and then iterate over the sorted keys to access the map values.
This pattern is especially useful when you need consistent output for testing, logging, or any scenario where the order matters. The sort package provides convenient functions like sort.Strings(), sort.Ints(), and sort.Sort() for custom types.
