You should use `const` to declare your `toNumberList` variable.
```js

Your `toNumberList` variable should be an arrow function.

Your `toNumberList` function should have an `args` parameter.

Your `toNumberList` function should use an implicit return.

```
Your `toNumberList` function should return the result of calling the `.split()` method of `args`.
```js

You should split `args` on the `,` character.
```js

You should chain the `.map()` method to the `.split()` method.

You should pass a reference to `parseFloat` as the callback to `.map()`.

If the ternary condition is true, your callback function should return the result of calling `apply()`.
```js

You should pass `fn` as the first argument to your `apply()` call.
```js

You should pass `args` as the second argument to your `apply()` call.
```js

If the ternary is false, you should return `match`.
