Takes any number of iterable objects or objects with a `length` property and returns the longest one.
If multiple objects have the same length, the first one will be returned.
Returns `undefined` if no arguments are provided.
- Use `Array.prototype.reduce()`, comparing the `length` of objects to find the longest one.
- If multiple objects have the same length, the first one will be returned.
- Returns `undefined` if no arguments are provided.
```js
const longestItem = (...vals) => vals.reduce((a, x) => (x.length > a.length ? x : a));
