+### 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'
+```
