+  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).
