toSorted(): a sorted copy that preserves the original order

Useful to know

toSorted() returns a new sorted array instead of rearranging the original one. For example, [12, 3, 8].toSorted((a, b) => a - b) gives [3, 8, 12]. The numerical comparison function is an essential . [1]

This helps with the "By price" interface, when you need to keep the order of receipt as well. The copy is shallow: an edit of an object property can be seen through both arrays. Check support in the target environment before using the method in an application for older browsers.
