How to get the original name of loop variables in JavaScript?

May 25, 2023

In the following example code, the function "getOriginalName" does not exist, but that is what I am looking for:

for(let variable of [var1, var2, var3]) {
    console.log("Value: " + variable);
    console.log("Name: " + getOriginalName(variable));
}

In my dreams, getOriginalName would return "var1", "var2" and "var3".

I know that you can access the name of variable "x" with:

varName = Object.keys({x})[0]

However, in my case this does not get me far, as the loop variable is called "variable" in each iteration.
So is there no way to iterate over a list of variables and still get the name of these variables?

>Solution :

Based on your comment, you can use an object containing key value pairs:

let var1 = 1;
let var2 = 2;
let var3 = 3;

Object.entries({
  var1,
  var2,
  var3
}).forEach(([k, v]) => {
  console.log("Name: " + k);
  console.log("Value: " + v);
});
