默认情况下，调用 readableStream.getReader() 而不传入任何参数时，会返回一个 ReadableStreamDefaultReader 实例。默认读取器将通过流传递的数据块视为不透明值，这允许 <ReadableStream> 可以处理几乎任何 JavaScript 值。

🌐 By default, calling readableStream.getReader() with no arguments will return an instance of ReadableStreamDefaultReader. The default reader treats the chunks of data passed through the stream as opaque values, which allows the <ReadableStream> to work with generally any JavaScript value.
