https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/copyWithin copyWithin uses shallow copy.
Example:
assert ['a', 'b', 'c', 'd', 'e'].copyWithin(0, 3, 4) == @['d', 'b', 'c', 'd', 'e'] assert ['a', 'b', 'c', 'd', 'e'].copyWithin(1, 3) == @['a', 'd', 'e', 'd', 'e'] assert [1, 2, 3, 4, 5].copyWithin(-2) == @[1, 2, 3, 1, 2] assert [1, 2, 3, 4, 5].copyWithin(0, 3) == @[4, 5, 3, 4, 5] assert [1, 2, 3, 4, 5].copyWithin(0, 3, 4) == @[4, 2, 3, 4, 5] assert [1, 2, 3, 4, 5].copyWithin(-2, -3, -1) == @[1, 2, 3, 3, 4]
