Variable name as a string in Javascript

Typically, you would use a hash table for a situation where you want to map a name to some value, and be able to retrieve both.

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

Like Seth's answer, but uses Object.keys() instead:

const varToString = varObj => Object.keys(varObj)[0]

const someVar = 42
const displayName = varToString({ someVar })
console.log(displayName)

You can use the following solution to solve your problem:

const myFirstName = 'John'
Object.keys({myFirstName})[0]

// returns "myFirstName"
