7. Else,
a. Let insertCount be the number of actual arguments minus 2.
b. Let dc be ? ToInteger(deleteCount).
c. Let actualDeleteCount be min(max(dc, 0), len - actualStart).
...
11. Repeat, while k < actualDeleteCount
a. Let from be ! ToString(actualStart+k).
b. Let fromPresent be ? HasProperty(O, from).
c. If fromPresent is true, then
i. Let fromValue be ? Get(O, from).
ii. Perform ? CreateDataPropertyOrThrow(A, ! ToString(k), fromValue).
d. Increment k by 1.
