How to inject data obtained from result(var) to result1(var) in golang

Question

1. terraform.tfstate is the input file and packageservicelist.tf.json is the output file.
2. Both are converted into Map Files
3. The data which I traversed is stored in result & I want to copy the data from result to result1.
4. Will Write operations works here. If yes . How ?

package main

import (  
    "fmt"
    "io/ioutil"
    "encoding/json"
)

func main() {  
    //File Reading terraform.tfstate

    data, err := ioutil.ReadFile("terraform.tfstate")
    if err != nil {
        //fmt.Println("File reading error", err)
        return
    }
// Map is save in m
    m := make(map[string]interface{})
    json.Unmarshal(data, &m)
   result:= m["resources"].([]interface{})[0].(map[string]interface{})["instances"].([]interface{})[0].(map[string]interface{})["attributes"].(map[string]interface{})["packaged_service_list"].([]interface{})[0].(map[string]interface{})["package_service"]
   fmt.Println(result)

//File Reading packageservicelist.tf.json

    data1, err :=ioutil.ReadFile("./linear/packageservicelist.tf.json")
    if err != nil {
        fmt.Println("File reading error", err)
        return
    }

    m1 := make(map[string]interface{})
    json.Unmarshal(data1, &m1)
    fmt.Println("\n")
    result1:= m1["resource"].(map[string]interface{})["api_packageservicelist"].(map[string]interface{})["packageservicelist"].(map[string]interface{})["packaged_service_list"].(map[string]interface{})["package_service"]
    fmt.Println(result1)







}

Both result and result1 have the value of the key package_service coming from different sources. You want to put result instead of result1. They, you have to write to that key:

m1["resource"].(map[string]interface{})["api_packageservicelist"].(map[string]interface{})["packageservicelist"].(map[string]interface{})["packaged_service_list"].(map[string]interface{})["package_service"]=result

Then when you write m1, the contents of the package_service from the first file will be written.
