That would be:

```js
let newArray = originalArray.slice().sort();
// or
let newArray = Array.from(originalArray).sort();
// or
let newArray = [...originalArray].sort();
```

I don't know that we need a new static for it. Unless the motivation is to
allow insertion sort or other sort algorithms that work best when creating
a new array as a result? But if we assume `Array.prototype.sort` already
uses quicksort or mergesort or similar, I'm not seeing much reason to add a
new static to allow insertsion sort or similar...

Can you expand on use cases and why the above aren't sufficient?
