Language Help JavaScript

Hi
This snippet of code

const array1 = [‘a’, ‘b’, ‘c’, ‘d’];
const newOrder = array1.toReversed();
console.log(newOrder);

produces the error
/home/ccuser/workspace/arrays-review-arrays/main.js:13
const reversedItems = items.toReversed();
^

TypeError: items.toReversed is not a function
at Object. (/home/ccuser/workspace/arrays-review-arrays/main.js:13:29)

what am I doing wrong?

You’ll likely need to update your version of Node. You can check with node -v

It wasn’t working for me with v18.18, so I updated to 20.9 - I used the installer here: Node.js

After updating to 20.9 .toReversed() now works for me!
