ReadableStreamBYOBReader.cancel()
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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()).
Syntax

Return value
A Promise, which fulfills with the value given in the reason
parameter.

ReadableStreamBYOBReader, or the stream has no owner.
