# --description--
Nell'oggetto crea un'altra proprietà chiamata `button functions`. Dai a questa proprietà un array contenente le tre funzioni assegnate alle proprietà `onclick` nella funzione `goTown`. Ricorda che queste funzioni sono variabili, non stringhe e non dovrebbero essere racchiuse tra virgolette.
# --hints--
Il primo oggetto di `locations` dovrebbe avere una proprietà `button functions`.
```js
assert.isDefined(locations[0]["button functions"]);
```
La proprietà `button functions` dovrebbe essere un array.
```js
assert.isArray(locations[0]["button functions"]);
```
La proprietà `button functions` dovrebbe avere tre valori al suo interno.
```js
assert.lengthOf(locations[0]["button functions"], 3);
```
Il primo valore dell'array `button functions` dovrebbe essere la funzione `goStore`.
```js
assert.equal(locations[0]["button functions"][0], goStore);
```
Il secondo valore dell'array `button functions` dovrebbe essere la funzione `goCave`.
```js
assert.equal(locations[0]["button functions"][1], goCave);
```
Il terzo valore dell'array `button functions` dovrebbe essere la funzione `fightDragon`.
```js
assert.equal(locations[0]["button functions"][2], fightDragon);
```
