    Class Blob

    Represents a blob, which is a file-like object of immutable, raw data. Can be read as text or binary data. Currently the binary data is only supported as Uint8Array.

    socket.onmessage = async (event) => {
        if (event.data instanceof Blob) {
            // Binary frame, can be retrieved as either Uint8Array or string
            let bytes = await event.data.bytes();
            let text = await event.data.text();

            print("Received binary message, printing as text: " + text);
        }
    });
