It also returns the array `arr` after the reversal.

[recent browser="new"]
The method [arr.toReversed](mdn:js/Array/toReversed) works similarly to the reverse method.
However, it does not change the original array.

For example:

```js run
const array = [1, 2, 3, 4, 5];
const reversedArray = array.toReversed();
console.log(array); // [1, 2, 3, 4, 5]
console.log(reversedArray); // [5, 4, 3, 2, 1]
```
