description: >
Returns false if this has valid numeric index and a detached buffer
info: |
9.4.5.3 [[DefineOwnProperty]] ( P, Desc)
...
3. If Type(P) is String, then
a. Let numericIndex be ! CanonicalNumericIndexString(P).
b. If numericIndex is not undefined, then
...
xi. If Desc has a [[Value]] field, then
1. Let value be Desc.[[Value]].
2. Return ? IntegerIndexedElementSet(O, intIndex, value).
...
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).
