Convert back and from object to JSON with references

Demo

Code:

const objectToJsonRefs = require('object-to-json-refs');

const obj = {
    actor: [
        { name: 'Robert Travolta' },
        { name: 'Jhon Schwarzenegger' },
        { name: 'Arnold De Niro' }
    ],
    fictionalCharacter: {
        male: [
            { name: 'Stan Mertens' },
            { name: 'Homer Smith' },
            { name: 'Finn Simpson' }
        ],
        female: [
            { name: 'Francine Bubblegum' },
            { name: 'Marge Ling' },
            { name: 'Princess Bouvier' }
        ]
    },
    myFavouriteCelebrities: [
    ],
    lastSeen: null
};
obj.myFavouriteCelebrities[0] = obj.actor[0];
obj.myFavouriteCelebrities[1] = obj.fictionalCharacter.male[2];
obj.lastSeen = obj.fictionalCharacter.female[0];

const result = objectToJsonRefs.ConvertToJsonRefsReady(obj);
console.log('forth:\n', JSON.stringify(result, null, 4));

const back = objectToJsonRefs.JsonRefReadyToObject(result);
console.log('back:\n', JSON.stringify(back, null, 4));

console.log('references still equal:\n', [
    back.myFavouriteCelebrities[0] === back.actor[0],
    back.myFavouriteCelebrities[1] === back.fictionalCharacter.male[2],
    back.lastSeen === back.fictionalCharacter.female[0]
]);
