How to convert Struct fields into Map String?

The below code snippet declares a struct type MyStruct with fields Name and Score. A map named myMap has string keys and an empty interface as value created.

Example

package main

import (
	"encoding/json"
	"fmt"
)

type MyStruct struct {
	Name  string
	Score int
}

func main() {
	ms := MyStruct{Name: "John", Score: 34}

	var myMap map[string]interface{}
	data, _ := json.Marshal(ms)
	json.Unmarshal(data, &myMap)

	fmt.Println(myMap["Name"])
	fmt.Println(myMap["Score"])
}
