Checks if the provided predicate function returns `true` for at least one element in a collection.

- Use `Array.prototype.some()` to test if any elements in the collection return `true` based on `fn`.
- Omit the second argument, `fn`, to use `Boolean` as a default.

```js
const any = (arr, fn = Boolean) => arr.some(fn);
```

```js
any([0, 1, 2, 0], x => x >= 2); // true
any([0, 0, 1, 0]); // true
```
