+  2. If Type(P) is String, then
+    a. Let numericIndex be ! CanonicalNumericIndexString(P).
+    b. If numericIndex is not undefined, then

+      ii. Return true.

+  Assert: O is an Integer-Indexed exotic object.
+  Assert: Type(index) is Number.

+  Otherwise, let numValue be ? ToNumber(value).
+  Let buffer be O.[[ViewedArrayBuffer]].
+  If IsDetachedBuffer(buffer) is true, return false.
