 Use `Array.filter()` to filter out falsey values (`false`, `null`, `0`, `""`, `undefined`, and `NaN`).

 ```js
-const compact = (arr) => arr.filter(v => v);
+const compact = (arr) => arr.filter(Boolean);
 // compact([0, 1, false, 2, '', 3, 'a', 'e'*23, NaN, 's', 34]) -> [ 1, 2, 3, 'a', 's', 34 ]
 ```
