+ 1. If |stream|.[=ReadableStream/[[controller]]=] [=implements=]
+    {{ReadableStreamDefaultController}},
+  1. Perform ! [$ReadableStreamDefaultControllerEnqueue$](|stream|.[=ReadableStream/[[controller]]=],
+     |chunk|).

+  1. Assert: |stream|.[=ReadableStream/[[controller]]=] [=implements=]
+     {{ReadableByteStreamController}}.
+  1. Assert: |chunk| is an {{ArrayBufferView}}.
+  1. Let |byobRequest| be !
+     [$ReadableByteStreamControllerGetBYOBRequest$](|stream|.[=ReadableStream/[[controller]]=]).
+  1. If |byobRequest| is non-null, and |chunk|.\[[ViewedArrayBuffer]].\[[ArrayBufferData]] is the
+     same [=Data Block=] as |byobRequest|.\[[view]].\[[ViewedArrayBuffer]].\[[ArrayBufferData]],

But if it's transferred it will be detached, right? And if it's detached then [[ArrayBufferData]] is set to **null**: https://tc39.es/ecma262/#sec-detacharraybuffer
