Benchmark: Shifted Integer vs Array vs Uint8Array

Script Preparation code:

var int = 0
var arr = []
arr.length = 8
arr.fill(0)
var u8 = new Uint8Array(1)

Tests:

Shifted Integer
for (let i = 0; i < 1000; i +=1) { int = ((int << 1) | 1) & ~(i & 1) & 255 } console.info(int)
Array
for (let i = 0; i < 1000; i +=1) { arr.push(i & 1) arr.shift() } console.info(arr)
Uint8Array
for (let i = 0; i < 1000; i +=1) { u8 = ((u8 << 1) | 1) & ~(i & 1) } console.info(u8)
