Variable name as a string in Javascript

Question

Is there a way to get a variable name as a string in Javascript? (like NSStringFromSelector in Cocoa)

I would like to do like this:

var myFirstName =         


        

Answer 1

This worked using Internet Explorer (9, 10 and 11), Google Chrome 5:

   
var myFirstName = "Danilo";
var varName = Object.keys({myFirstName:0})[0];
console.log(varName);
