ReadableStreamBYOBReader.releaseLock()
Draft: This page is not complete.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The releaseLock() method of the ReadableStreamBYOBReader interface releases the reader's lock on the stream. After the lock is released, the reader is no longer active.
If the associated stream is errored when the lock is released, the reader will appear errored in that same way subsequently; otherwise, the reader will appear closed.
A reader’s lock cannot be released while it still has a pending read request, i.e., if a promise returned by the reader’s ReadableStreamBYOBReader.read() method has not finished. This will result in a TypeError being thrown.
