Benchmark: Array include vs object key vs Set has V2

Script Preparation code:

var reports = (new Array(200)).fill(null).reduce((prev, newVal) => {prev.push({type: Math.random() + ''}); return prev; }, [{ type: 'core' }]);
var SERVICES = [{ type: 'core' }, { type: 'foo' },{ type: 'bar' }];

Tests:

Array.includes()
var has; var array = SERVICES.map((service) => service.type); for (report of reports) { if(array.includes(report.type)) { has = true; } }
Object[key]
var has; var object = SERVICES.reduce((result, service) => { result[service.type] = service.type; return result; }, {}); for (report of reports) { if(object[report.type]) { has = true; } }
Set.has()
var has; var set = new Set(SERVICES.map((service) => service.type)); for (report of reports) { if(set.has(report.type)) { has = true; } }
