The writable read-only property of the TransformStream interface returns the WritableStream instance controlled by this TransformStream.
The following example creates a new TransformStream as a textEncoderStream, and prints the value of writable to the console.
const textEncoderStream = new TransformStream(); console.log(textEncoderStream.writable); // a WritableStream
