Benchmark: Set.has vs Array.includes for small number of items (fixed)

Script Preparation code:

const item_1 = Math.floor(1 / 2);
const array_1 = new Array(1).fill(0).map((_, i) => i);
const set_1 = new Set(array_1);

const item_2 = Math.floor(2 / 2);
const array_2 = new Array(2).fill(0).map((_, i) => i);
const set_2 = new Set(array_2);

const item_4 = Math.floor(4 / 2);
const array_4 = new Array(4).fill(0).map((_, i) => i);
const set_4 = new Set(array_4);

const item_8 = Math.floor(8 / 2);
const array_8 = new Array(8).fill(0).map((_, i) => i);
const set_8 = new Set(array_8);

Tests:

array_1
array_1.includes(item_1)
set_1
set_1.has(item_1)
array_2
array_2.includes(item_2)
set_2
set_2.has(item_2)
array_4
array_4.includes(item_4)
set_4
set_4.has(item_4)
array_8
array_8.includes(item_8)
set_8
set_8.has(item_8)
