byobRequest

The byobRequest read-only property of the ReadableByteStreamController interface returns the current BYOB request, or null if there are no pending requests.

An underlying byte source should check this property, and use it to write data to the stream if it exists (rather than using ReadableByteStreamController.enqueue()). This will result in an efficient zero-byte transfer of the data to the consumer.

Value

A ReadableStreamBYOBRequest object instance, or null.
