Are you sure about this? You might be mixing ArrayBuffer (which is a transferrable object[0] and gets zero-copy moved) and SharedArrayBuffer. From [1]: > The structured clone algorithm accepts SharedArrayBuffer objects and typed arrays mapped onto SharedArrayBuffer objects. In both cases, the SharedArrayBuffer object is transmitted to the receiver resulting in a new, private SharedArrayBuffer object in the receiving agent (just as for ArrayBuffer). However, the shared data block referenced by the two SharedArrayBuffer objects is the same data block, and a side effect to the block in one agent will eventually become visible in the other agent.
