Script Preparation code:

var size = 450000;
var buf = new ArrayBuffer(size);

var normalArray = new Array(size);
var arrayFromBuffer = new Uint8Array(buf);
var arrayWithoutBuffer = new Uint8Array(size);

Tests:

Array
for (i =0; i< size; i++){ normalArray[i] = 0; }
typed array from Buffer
for (i =0; i< size; i++){ arrayFromBuffer[i] = 0; }
typed Array no buffer
for (i =0; i< size; i++){ arrayWithoutBuffer[i] = 0; }
