I'm trying to reference self-key to in a JSON file in a simple Hello World NodeJS app.

{
    "person": {
        "first_name": "Aminul",
        "last_name": "Islam"
    },
    "full_name": "{$person.first_name} {$person.last_name}"
}

and the app file.

const person = require('./app.json');

console.log(person.full_name);

Expecting result:

Aminul Islam

Result:

{$person.first_name} {$person.last_name}
