# --description--

In JavaScript, the `change` event is used to detect when the value of an HTML element has changed:

```js
element.addEventListener("change", () => {
    
});
```

Attach the `addEventListener` method to the `dateOptionsSelectElement`. The first argument of the event listener should be the string `"change"` and the second argument should be an empty arrow function.

# --hints--

You should attach the `addEventListener` method to the `dateOptionsSelectElement`.

```js
assert(code.match(/dateOptionsSelectElement\.addEventListener\s*\(/g));
```

Your event listener should listen for a `"change"` event.

```js
assert(code.match(/dateOptionsSelectElement\.addEventListener\s*\(\s*('|")change\1/g));
```

You should add an empty arrow function as the second argument to the `addEventListener` method.

```js
assert(code.match(/dateOptionsSelectElement\.addEventListener\s*\(\s*('|")change\1\s*,\s*\(\s*\)\s*=>\s*{\s*}/g));
```
