How to create a dynamic variable name by concatenating two strings in golang? : I want to a create variable name by concatenating with current date and provide a value to the created variable name. My variable name should look something like this **"Key-2019-01"**. so that i can store the value as **var Key-2019-01 = "yes"**

I have tried like the below.
        
    

         package main
         import (
	     "fmt"
	     "time"
	     "strconv"
          "strings"	
         )

         func main() {
	    currentMonth := time.Now().Month()
	    currentYear := time.Now().Year()
	    var month = int(currentMonth)
	    var currentDate = strings.Join([]string{strconv.Itoa(currentYear), "-", strconv.Itoa(month)}, "")

	    var "Key",currentDate string
	
        value, err := json.Marshal("yes")
	    stub.PutState(("Key", currentDate), value)
         }      

It could be helpful if  I get a working code of this. Please help me in solving this. Thanks in advance.
