+  1. Let O be the this value.
+  2. Perform ? RequireInternalSlot(O, [[ArrayBufferData]]).
+  3. If IsSharedArrayBuffer(O) is true, throw a TypeError exception.
+  4. Return IsResizableArrayBuffer(O).

+  IsResizableArrayBuffer ( arrayBuffer )
+
+  1. Assert: Type(arrayBuffer) is Object and arrayBuffer has an
+     [[ArrayBufferData]] internal slot.
+  2. If buffer has an [[ArrayBufferMaxByteLength]] internal slot, return true.
+  3. Return false.
