How to check if two maps are equal in Go?

In Go, you can check if two maps are equal by comparing each key-value pair of the maps. Here is an example of how you can do it:

func mapsAreEqual(map1, map2 map[string]int) bool {
    // Check if the maps have the same length
    if len(map1) != len(map2) {
      return false
    }
  
    // Iterate over each key-value pair in map1
    for key, value := range map1 {
        // Check if the key exists in map2 and has the same value
        if v, ok := map2[key]; !ok || v != value {
            return false
        }
    }
  
    return true
}

func main() {
    map1 := map[string]int{
        "a": 1,
        "b": 2,
        "c": 3,
    }
  
    map2 := map[string]int{
        "a": 1,
        "b": 2,
        "c": 3,
    }
  
    if mapsAreEqual(map1, map2) {
        fmt.Println("Maps are equal")
    } else {
        fmt.Println("Maps are not equal")
    }
}

In the example above, the mapsAreEqual function checks if the length of the maps is the same, and then iterates over each key-value pair in map1. It checks if each key exists in map2 and if the corresponding values are equal. If at any point a mismatch is found, it returns false. Finally, in the main function, it calls mapsAreEqual and prints the appropriate message.
