# --description--
Crie três novas funções vazias chamadas `buyHealth`, `buyWeapon` e `goTown`.
# --hints--
Você deve declarar `buyHealth` com a palavra-chave `function`.
```js
assert.match(code, /function buyHealth/);
```
Você deve declarar `buyWeapon` com a palavra-chave `function`.
```js
assert.match(code, /function buyWeapon/);
```
Você deve declarar `goTown` com a palavra-chave `function`.
```js
assert.match(code, /function goTown/);
```
`buyHealth` deve ser uma função vazia.
```js
assert.equal(buyHealth.toString(), 'function buyHealth() {}');
```
`buyWeapon` deve ser uma função vazia.
```js
assert.equal(buyWeapon.toString(), 'function buyWeapon() {}');
```
`goTown` deve ser uma função vazia.
```js
assert.equal(goTown.toString(), 'function goTown() {}');
