# --description--

Add a third object to the `locations` array. Give it the same properties as the other two objects.

Set `name` to `cave`. Set `button text` to an array with the strings `Fight slime`, `Fight fanged beast`, and `Go to town square`. Set the `button functions` to an array with the variables `fightSlime`, `fightBeast`, and `goTown`. Set the `text` property to `You enter the cave. You see some monsters.`.

# --hints--

You should have three values in your `locations` array.

```js
console.log(locations);
assert.lengthOf(locations, 3);
```

Your third `locations` value should be an object.

```js
assert.isObject(locations[2]);
```

Your third `locations` object should have a `name` property with the value of `cave`.

```js
assert.equal(locations[2].name, "cave");
```

Your third `locations` object should have a `button text` property which is an array.

```js
assert.isArray(locations[2]["button text"]);
```

Your `button text` property should have the string values `Fight slime`, `Fight fanged beast`, and `Go to town square`.

```js
assert.equal(locations[2]["button text"][0], "Fight slime");
assert.equal(locations[2]["button text"][1], "Fight fanged beast");
assert.equal(locations[2]["button text"][2], "Go to town square");
```

Your third `locations` object should have a `button functions` property which is an array.

```js
assert.isArray(locations[2]["button functions"]);
```

Your `button functions` property should have the function values `fightSlime`, `fightBeast`, and `goTown`.

```js
assert.equal(locations[2]["button functions"][0], fightSlime);
assert.equal(locations[2]["button functions"][1], fightBeast);
assert.equal(locations[2]["button functions"][2], goTown);
```

Your third `locations` object should have a `text` property which is a string.

```js
assert.isString(locations[2].text);
```

Your third `locations` object should have a `text` property with the value of `You enter the cave. You see some monsters.`.

```js
assert.equal(locations[2].text, "You enter the cave. You see some monsters.");
```
