Syntax
writableStreamDefaultWriterInstance.releaseLock()
Parameters
None.
Return value
Void.
Examples
const writableStream = new WritableStream({
write(chunk) {
...
},
close() {
...
},
abort(err) {
...
}
}, queuingStrategy);
...
const writer = writableStream.getWriter();
...
// release writer's lock on the stream when desired
writer.releaseLock();
