### any
Returns `true` if the provided predicate function returns `true` for at least one element in a collection, `false` otherwise.
Use `Array.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
```
