Which turns out to be pretty inconvenient in Go. So more likely you’d do something like copy the keys to a slice, sort the slice, then iterate that to get the map values.

Incidentally, that’s exactly what the json package does when encoding a map.

Now you’re stuck with the fact that Go doesn’t support generics outside of the stock data structures.
