# --description--

Create three new empty functions called `buyHealth`, `buyWeapon`, and `goTown`.

# --hints--

You should declare `buyHealth` with the `function` keyword.

```js
assert.match(code, /function\s+buyHealth/);
```

You should declare `buyWeapon` with the `function` keyword.

```js
assert.match(code, /function\s+buyWeapon/);
```

You should declare `goTown` with the `function` keyword.

```js
assert.match(code, /function\s+goTown/);
```

`buyHealth` should be an empty function.

```js
assert.equal(buyHealth.toString(), 'function buyHealth() {}');
```

`buyWeapon` should be an empty function.

```js
assert.equal(buyWeapon.toString(), 'function buyWeapon() {}');
```

`goTown` should be an empty function.

```js
assert.equal(goTown.toString(), 'function goTown() {}');
```
