Benchmark: Set has vs object key (large dataset)

Script Preparation code:

var obj = (new Array(100000)).fill(null).reduce((prev, newVal) => {prev[Math.random() + ''] = Math.random() + ''; return prev; }, { sausage: 'tst' });
var array = Object.keys(obj);
var set = new Set(array);

Tests:

Includes
if(array.includes('sausage')) console.log("found");
Object[key]
if(obj['sausage']) console.log("found");
Set.has
if(set.has('sausage')) console.log("found");
