### 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'
|
|
```
