description: >
Returns undefined if key has a numeric index and object has a detached buffer
info: |
[[Get]] ( P, Receiver )
If Type(P) is String, then
Let numericIndex be ! CanonicalNumericIndexString(P).
If numericIndex is not undefined, then
Return ! IntegerIndexedElementGet(O, numericIndex).
IntegerIndexedElementGet ( O, index )
Assert: O is an Integer-Indexed exotic object.
Assert: Type(index) is Number.
Let buffer be O.[[ViewedArrayBuffer]].
If IsDetachedBuffer(buffer) is true, return undefined.
