I want to store the following into local storage with a structure like so:

```
{
  "stuff": [
    {
      "user1": {
        "numbers": [
          1,
          2,
          3
        ]
      },
      "user2": {
        "numbers": [
          2
        ]
      }
    }
  ]
}

```

How would I go about doing this?
