Benchmark: uint8Array vs plain array, small, random get/set

Script Preparation code:

const uint8Array = new Uint8Array(81);
const simpleArray = new Array(81);
let temp = 0;
let r = 0;

for(let i = 0; i < 81; i++) {
  uint8Array[i] = simpleArray[i] = Math.floor(Math.random() * 2);
}

Tests:

uint8Array get/set
for (let i; i < 10000; i++) { r = Math.floor(Math.random() * 81); temp = uint8Array[r]; r = Math.floor(Math.random() * 81); uint8Array[r] = temp; }
plain array get/set
for (let i; i < 10000; i++) { r = Math.floor(Math.random() * 81); temp = simpleArray[r]; r = Math.floor(Math.random() * 81); simpleArray[r] = temp; }
