# Deep Cloning (JSON.parse + JSON.stringify)

```js
const obj = {
  name: "Joe",
  address: { city: "X" },
};

const clone = JSON.parse(JSON.stringify(obj));
```

Copying using `spread` operator or `Object.assign()` makes a shallow copy (i.e, nested arrays & objects reference is copied instead of their values) whereas, `stringify + parse` does a deep copy.
