Description

The method would chop the list into pieces at a specified chop size (or chop sizes).

assert [1, 2, 3, 4].chop(1) == [[1]]
assert [1, 2, 3, 4].chop(1,-1) == [[1], [2, 3, 4]]
assert ('a'..'h').chop(2, 4) == [['a', 'b'], ['c', 'd', 'e', 'f']]
assert ['a', 'b', 'c', 'd', 'e'].chop(3) == [['a', 'b', 'c']]
assert ['a', 'b', 'c', 'd', 'e'].chop(1, 2, 3) == [['a'], ['b', 'c'], ['d', 'e']]
assert ['a', 'b', 'c', 'd', 'e'].chop(1, 2, 3, 3, 3) == [['a'], ['b', 'c'], ['d', 'e'], [], []]
