# --description--

Now call the `.forEach()` method of your `letters` array, and pass your `createLabel` function reference as the callback.

You should see some letters appear across the top of your spreadsheet.

# --hints--

You should call the `.forEach()` method on your `letters` array.

```js
assert.match(code, /letters\.forEach\(/);
```

You should pass your `createLabel` function reference to the `.forEach()` method.

```js
assert.match(code, /letters\.forEach\(\s*createLabel\s*\)/);
```

You should not pass a `createLabel` function call.

```js
assert.notMatch(code, /letters\.forEach\(\s*createLabel\(\s*\)\s*\)/);
```
