How to create a dynamic variable name by concatenating two strings
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.

no this is golang.if there is way for this in solution in javascript. i thought of trying the logic in golang

Dynamic variable name is not what you want. Have a look at a key/value pair... gobyexample.com/maps (Also I removed the irrelevant tags)

This is not possible in Go, since it's a compiled and statically typed language. The compiler has to know, at compile-time, the names and types of variables (*). What you ask is a run-time variable naming, which cannot work. However, it's extremely unlikely that you actually need this in practice. Maps can provide a similar capability:
m := make(map[string]string)
m["key"] = "value"
And you can construct either of these at run-time. Slightly adapting your example:
package main
import (
"fmt"
"strconv"
"strings"
"time"
)
func main() {
m := make(map[string]string)
currentMonth := time.Now().Month()
currentYear := time.Now().Year()
var month = int(currentMonth)
var currentDate = strings.Join(string{strconv.Itoa(currentYear), "-", strconv.Itoa(month)}, "")
m["key"+currentDate] = "value"
fmt.Println(m)
}
Prints out:
map[key2019-1:value]
(*) With some exceptions that are not relevant for this particular discussion.
