JavaScript: How to get name of the constant?

Question

I want to get the name of constant :

const MY_CONSTANT = 1;

I want to show the name of my constant (MY_CONSTANT) not value (1).

You're going to have to explain the situation more thoroughly because it doesn't make sense as it is. — Pointy, May 23 '16 at 14:02
If you know the constant's name, can't you just print it ? `alert("MY_CONSTANT");` — Rosh Donniet, May 23 '16 at 14:02

Just use `if someValue === MY_CONSTANT then print("MY_CONSTANT")` This is pseudocode. — sebenalern, May 23 '16 at 14:09
`const MY_CONSTANT = { name: "MY_CONSTANT", value: 1 }; console.log(MY_CONSTANT.name);` — Marcio J, Apr 23 '23 at 17:27

You cannot get the name of the constant or a variable in JavaScript. The closest thing to what you want to do would be setting a property inside an object. Then, you can get the names of all keys.

var obj = { myFirstName: 'John' };
obj.foo = 'Another name';
for(key in obj)
    alert(key + ': ' + obj[key]);
