The following example shows how to set the first Uint8 in the DataView.

var req = new XMLHttpRequest();
     req.open('GET', "http://www.example.com");
     req.responseType = "arraybuffer";
     req.send();

     req.onreadystatechange = function () {
         if (req.readyState === 4) {
             var buffer = req.response;
             var dataView = new DataView(buffer);
             dataView.setUint8(0, 9);
         }
     }

Remarks
