Returns true after setting value

9.4.5.5 [[Set]] ( P, V, Receiver)
...
2. If Type(P) is String, then
a. Let numericIndex be ! CanonicalNumericIndexString(P).
b. If numericIndex is not undefined, then
i. Perform ? IntegerIndexedElementSet(O, numericIndex, V).
ii. Return true.
...
IntegerIndexedElementSet ( O, index, value )
Assert: O is an Integer-Indexed exotic object.
If O.[[ContentType]] is BigInt, let numValue be ? ToBigInt(value).
Otherwise, let numValue be ? ToNumber(value).
Let buffer be O.[[ViewedArrayBuffer]].
If IsDetachedBuffer(buffer) is false and ! IsValidIntegerIndex(O, index) is true, then
Let offset be O.[[ByteOffset]].
Let arrayTypeName be the String value of O.[[TypedArrayName]].
Let elementSize be the Element Size value specified in Table 62 for arrayTypeName.
Let indexedPosition be (ℝ(index) × elementSize) + offset.
Let elementType be the Element Type value in Table 62 for arrayTypeName.
Perform SetValueInBuffer(buffer, indexedPosition, elementType, numValue, true, Unordered).
Return NormalCompletion(undefined).
