# --description--

Just like array values, object properties are separated by a comma. Add a comma after your `name` property and add a `button text` property with the value of an empty array. Note that because the property name has more than one word, you'll need to surround it in quotes.

For example:

```js
{
    name: "Naomi",
    "favorite color": "purple"
}
```

# --hints--

Your first `locations` value should be an object.

```js
assert.isObject(locations[0]);
```

Your first `locations` value should have a `button text` property.

```js
assert.isDefined(locations[0]["button text"]);
```

Your first `locations` value should have a `button text` property with a value that is an array.

```js
assert.isArray(locations[0]["button text"]);
```

Your first `locations` value should have a `button text` property with a value that is an empty array.

```js
assert.equal(locations[0]["button text"].length, 0);
```

You should not remove or change the `name` property.

```js
assert.equal(locations[0].name, "town square");
```
