Intuitive and powerful language for building webapps that fly

function incr32(iv) {
    var len = iv.length;
    var item;
    while (len--) {
        item = iv.readUInt8(len);
        if (item === 255) {
            iv.writeUInt8(0, len);
        }
        else {
            item++;
            iv.writeUInt8(item, len);
            break;
        }
