ReadableStream.locked

The locked read-only property of the ReadableStream interface returns whether or not the readable stream is locked to a reader.

A readable stream can have at most one active reader at a time, and is locked to that reader until it is released. A reader might be obtained using ReadableStream.getReader() and released using the reader's releaseLock() method.

Value

A boolean value indicating whether or not the readable stream is locked.
