Spreading a Realm.Object gives in an empty object

Goals

I would like to be able to easily convert a Realm.Object to a plain-ol’-javascript-object.

Expected Results

When doing a JS spread on a Realm.Object I would expect the resulting object contained the same properties as the Realm.Object.

Actual Results

You get an empty object.

Steps to Reproduce & Code Sample

const Realm = require('realm')
const realm = new Realm({ schema: [ { name: "Person", properties: { name: "string" } } ] });
realm.write(() => { realm.create("Person", { name: "Alice" }) });
const persons = realm.objects("Person"); // 👉Results { [0]: RealmObject { [name]: 'Alice' } }
const alice = persons[0]; // 👉RealmObject { [name]: 'Alice' }
Object.keys(alice) // 👉[ 'name' ]
Object.getOwnPropertyNames(alice) // 👉[ '_realm', 'name' ]
alice.hasOwnProperty('name') // 👉true
Object.getOwnPropertyDescriptors(alice)
/* 👇
{ _realm:
   { value: Realm {},
     writable: true,
     enumerable: false,
     configurable: false },
  name:
   { value: 'Alice',
     writable: true,
     enumerable: false,
     configurable: true } }
*/
{ ...alice } // 👉{}

An interesting observation is that getOwnPropertyNames contains 'name' but Object.hasOwnProperty(alice, 'name') is false 🤷‍♂️

This works for me.

let data = realm.objectForPrimaryKey('User', 10);

data = JSON.parse(JSON.stringify(data));

console.log({...data, name: 'Bob'});

If people are interested I published to npm an eslint-plugin that bans spread on Realm.Object type. https://www.npmjs.com/package/@waltari/eslint-plugin-ban-realm-spread

(hopefully spread operator wont be fixed now the next day)
