You can do this by creating a new, empty map and then iterating over the old map in a for range loop to assign the appropriate key-value pairs to the new map. It is the simplest and most efficient solution to this problem in Go. As you see in the output, the copied map is a deep clone, and adding new elements does not affect the old map.
