Benchmark: DataView vs Uint8Array by bytes vs Uint8Array set Uint8Array

Script Preparation code:

var size = 0xFF;
var buf = new ArrayBuffer(size);
var view = new DataView(buf);
var byte = new Uint8Array(buf);

var data = [];

for (let i = 0; i < size; i++) {
    data[i] = 100 * Math.random();
}

var dataBytes = new Uint8Array(data);

Tests:

DataView
for (let i; i < size; i++) { view.setUint8(i, data[i]); }
Uint8Array by byte
for (let i; i < size; i++) { byte[i] = data[i]; }
Uint8Array with set
byte.set(data, 0);
Uint8Array with set other Uint8Array
byte.set(dataBytes, 0);
