Benchmark: Value existance check in object, array, map, set

Script Preparation code:

var randomStringsToGenerate = 10000;

var array = [];
var set = new Set();
var object = {};
var map = new Map();

for (let i = 0; i < randomStringsToGenerate; i++) {
  array.push(i);
  map.set(i, true);
  object[i] = true;
  set.add(i);
}

Tests:

array
return array.includes(5000)
set
return set.has(5000)
object
return object[5000]
map
return map.has(5000)
