Script Preparation code:

var numberOfElements = 50000
var arr = [];
for (let i = 0; i < numberOfElements; i++) arr.push(i);


var set = new Set(arr);

Tests:

Array - iteration
for (const x of arr) {}
Set - iteration
for (const x of set) {}
Array - includes
const value = numberOfElements - 1; arr.includes(value)
Set - has
const value = numberOfElements - 1; set.has(value)
Array - push
arr.push(numberOfElements + 1)
Set - add
set.add(numberOfElements + 1)
Array - deletion
const value = numberOfElements - 1; const index = arr.indexOf(value); arr.splice(index, 1);
Set - deletion
const value = numberOfElements - 1; set.delete(value);
Converting a Set to an Array
const array = Array.from(set);
