Get object property name as a string

Question

Is it possible to get the object property name as a string

person = {};
person.first_name = \'Jack\';
person.last_name = \'Trades\';
person.address = {};
per         


        

Answer 1

No, it's not possible.

Imagine this:

person.age = 42;
person.favoriteNumber = 42;

var pn = propName(person.age)
// == propName(42)
// == propName(person.favoriteNumber);

The reference to the property name is simply lost in that process.
