Script Preparation code:

var size = 10 * 1024 * 1024;

var buf = new ArrayBuffer(size);
var u8 = new Uint8Array(buf);

var buf2 = new ArrayBuffer(size);
var view = new DataView(buf2);

Tests:

setuint8
for (let i = 0; i < size; i++) { u8[i] = 42; }
uint8array
for (let i = 0; i < size; i++) { view.setUint8(i, 43); }
