WritableStreamDefaultWriter

The closed read-only property of the WritableStreamDefaultWriter interface returns a Promise that fulfills if the stream becomes closed, or rejects if the stream errors or the writer's lock is released.

The desiredSize read-only property of the WritableStreamDefaultWriter interface returns the desired size required to fill the stream's internal queue.

The ready read-only property of the WritableStreamDefaultWriter interface returns a Promise that resolves when the desired size of the stream's internal queue transitions from non-positive to positive, signaling that it is no longer applying backpressure.

The abort() method of the WritableStreamDefaultWriter 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.

The close() method of the WritableStreamDefaultWriter interface closes the associated writable stream.

The close() method of the WritableStreamDefaultWriter interface closes the associated writable stream.

The releaseLock() method of the WritableStreamDefaultWriter interface releases the writer's lock on the corresponding stream.

The write() method of the WritableStreamDefaultWriter interface writes a passed chunk of data to a WritableStream and its underlying sink, then returns a Promise that resolves to indicate the success or failure of the write operation.
