 *    work:
 *
 *    .. code-block:: js
 *
 *        // Incorrectly convert a TypedArray.
 *        // Produces a Uint16Array that points to the entire WASM memory!
 *        let myarray = new Uint16Array(buffer.data.buffer);
 *
 *    Instead, if you want to convert the output TypedArray, you need to say:
 *
 *    .. code-block:: js
 *
 *        // Correctly convert a TypedArray.
 *        let myarray = new Uint16Array(
 *            buffer.data.buffer,
 *            buffer.data.byteOffset,
 *            buffer.data.byteLength
