+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
+```
