Convert JSON to Map in Golang

package main

import (
    "encoding/json"
    "fmt"
)

func main() {

    str := `{"id":1,"name":"Name 1","price":5.6,"status":true}`

    var product = make(map[string]interface{})

    err := json.Unmarshal([]byte(str), &product)

    if err != nil {
        fmt.Println(err.Error())
    } else {
        fmt.Println(product)
    }

}      
        

Output

map[id:1 name:Name 1 price:5.6 status:true]
