This module wraps core JavaScript functions.

Unless your application has very specific requirements and solely targets JavaScript, you should be using the relevant functions in the math, json, and times stdlib modules instead.

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]
