### forEachRight Executes a provided function once for each array element, starting from the array's last element. Use `Array.slice(0)` to clone the given array, `Array.reverse()` to reverse it and `Array.forEach()` to iterate over the reversed array. ```js const forEachRight = (arr, callback) => arr .slice(0) .reverse() .forEach(callback); ``` ```js forEachRight([1, 2, 3, 4], val => console.log(val)); // '4', '3', '2', '1' ```
