## Description
The `split` method returns an array of strings from a larger string by using its argument to determine where to make each split:
```js
"a b c".split(" "); // ["a", "b", "c"];
```
Add a function `toNumberList` (inside `applyFn`) which takes an argument `args` and splits it by commas. Return `toNumberList`.
## Instructions
