a. Let k be actualStart.
b. Repeat, while k < (len - actualDeleteCount)
i. Let from be ! ToString(k+actualDeleteCount).
ii. Let to be ! ToString(k+itemCount).
iii. Let fromPresent be ? HasProperty(O, from).

2. Perform ? Set(O, to, fromValue, true).
v. Else fromPresent is false,

vi. Increase k by 1.
c. Let k be len.
d. Repeat, while k > (len - actualDeleteCount + itemCount)
i. Perform ? DeletePropertyOrThrow(O, ! ToString(k-1)).
ii. Decrease k by 1.
