In Go, you can copy a map using a loop to create a new map and then populate it with key-value pairs from the original map.
Here’s an example of how to do this:
package main
import "fmt"
func main() {
// Original map
originalMap := map[string]int{"one": 1, "two": 2, "three": 3}
// Creating a new map
copiedMap := make(map[string]int)
// Copying the original map to the new map
for key, value := range originalMap {
copiedMap[key] = value
}
// Displaying both maps
fmt.Println("Original Map:", originalMap)
fmt.Println("Copied Map:", copiedMap)
}
