 Use `.filter()` to filter falsey values. For example false, null, 0, "", undefined, and NaN are falsey.
 
 ```js
-const compact = (arr) => arr.filter( v => [0, null, false, '', undefined].indexOf(v) === -1 && v);
+const compact = (arr) => arr.filter(v => v);
 // compact([0, 1, false, 2, '', 3, 'a', 'e'*23, NaN, 's', 34]) -> [ 1, 2, 3, 'a', 's', 34 ]
