<!--your preparation HTML code goes here-->

Script Preparation code:

const array_1 = new Array(1).map((_, i) => self.crypto.randomUUID()
);
const set_1 = new Set(array_1);
const item_1 = array_1[0];

const array_2 = new Array(1, 2).map((_, i) => self.crypto.randomUUID()
);
const set_2 = new Set(array_2);
const item_2 = array_2[1];

const array_4 = new Array(1, 2, 3, 4).map((_, i) => self.crypto.randomUUID()
);
const set_4 = new Set(array_4);
const item_4 = array_2[3];

const array_8 = new Array(1, 2, 3, 4, 5, 6, 7, 8).map((_, i) => self.crypto.randomUUID()
);
const set_8 = new Set(array_8);
const item_8 = array_2[7];

Tests:

array_1
array_1.includes(item_1)
set_1
set_1.has(item_1)
array_8
array_8.includes(item_8)
set_8
set_8.has(item_8)
