+  ValidateTypedArray ( O )
+    The abstract operation ValidateTypedArray takes argument O. It performs the following steps when called:
+
+    Perform ? RequireInternalSlot(O, [[TypedArrayName]]).
+    Assert: O has a [[ViewedArrayBuffer]] internal slot.
+    Let buffer be O.[[ViewedArrayBuffer]].
+    If IsDetachedBuffer(buffer) is true, throw a TypeError exception.
