     * A text string. The string is added to the buffer in UTF-8 format, and the value of bufferedAmount is increased
     * by the number of bytes required to represent the UTF-8 string.
     * - **ArrayBuffer**
     * You can send the underlying binary data used by a typed array object; its binary data contents are queued in
     * the buffer, increasing the value of bufferedAmount by the requisite number of bytes.
     * - **Blob**
     * Specifying a Blob enqueues the blob's raw data to be transmitted in a binary frame. The value of bufferedAmount
     * is increased by the byte size of that raw data.
     * - **ArrayBufferView**
     * You can send any JavaScript typed array object as a binary frame; its binary data contents are queued in the
     * buffer, increasing the value of bufferedAmount by the requisite number of bytes.
