Check the Browser compatibility table carefully before using this in production.
The closed getter property of the ReadableStream interface returns a promise that fulfills if the stream becomes closed or the reader's lock is released, or rejects if the stream errors.
Syntax
var closed = readableStreamDefaultReaderInstance.closed;Value
A Promise.
Examples
In this snippet, a previously-created reader is queried to see if the stream has been closed. When it is closed, the promise fulfills and the message is logged to the console.
reader.closed.then(() => {
console.log('reader closed');
})
