How do I merge two maps in Go?

In Go, you can merge two maps by iterating over the second map and adding its key-value pairs to the first map. Below is an example demonstrating how to achieve this:


package main import "fmt" func main() { // First map map1 := map[string]int{ "apple": 5, "banana": 10, } // Second map map2 := map[string]int{ "banana": 3, "orange": 7, } // Merging map2 into map1 for key, value := range map2 { map1[key] += value } fmt.Println(map1) // Output: map[apple:5 banana:13 orange:7] }
