postMessage

fun postMessage(message: Any?, transfer: ReadonlyArray<Transferable>)(source)

Posts a message through the channel. Objects listed in transfer are transferred, not just cloned, meaning that they are no longer usable on the sending side.

Throws a "DataCloneError" DOMException if transfer contains duplicate objects or port, or if message could not be cloned.
