cancel method

JSPromise<JSAny?> cancel([
  1. JSAny? reason
])

The cancel() method of the ReadableStreamBYOBReader interface returns a Promise that resolves when the stream is canceled. Calling this method signals a loss of interest in the stream by a consumer.

Note: If the reader is active, the cancel() method behaves the same as that for the associated stream (ReadableStream.cancel).

Implementation

external JSPromise<JSAny?> cancel([JSAny? reason]);
