JavaScriptでUint8Arrayをdump

Uint8Array.prototype.dump = function() {
    var t = "";
    for (var i = 0; i < this.length; i++) {
        t += String(this[i]);
        if (i %  4 ==  3) t += " ";
        if (i % 16 == 15) t += "\n";
    }
    return t;
};
var a = new Uint8Array([0,0,0,0,0,0,0,1,0,0,1,0,0,0,1,1,0,1,0,0,0,1,0,1]);
a.dump();

0000 0001 0010 0011 
0100 0101 

雑感
