The use of `new Array(length)` in clone() appears to contradict previous advice on elements kinds (https://v8.dev/blog/elements-kinds …) - doesn't that make a holey array instead of a packed array? Isn't push() better for preserving packed elements?

It does, but it also has a benefit: // Pre-allocate the correct number of elements, to avoid // having to grow the array. It’s a trade-off between optimizing array creation itself vs. optimizing operations on the array. More details:https://www.youtube.com/watch?v=m9cTaYI95Zc&t=23m48s …
