The abort() method of the WritableStream interface aborts the stream, signaling that the producer can no longer successfully write to the stream and it is to be immediately moved to an error state, with any queued writes discarded.
Optionalreason: anyThe close() method of the WritableStream interface closes the associated stream. All chunks written before this method is called are sent before the returned promise is fulfilled.
The getWriter() method of the WritableStream interface returns a new instance of WritableStreamDefaultWriter and locks the stream to that instance. While the stream is locked, no other writer can be acquired until this one is released.
The
lockedread-only property of the WritableStream interface returns a boolean indicating whether the WritableStream is locked to a writer.MDN Reference
