You can do with reduce API from Javascript.

Your objects input:

var yourObj = { item1: {"id": 1, "title": "Anne", "Finalist": true}, item2: {"id":2, "title": "Sam", "Finalist": false}, item3: {"id":3, "title": "Lexi", "Finalist": true}};var allowed = ['item1', 'item3'];var filteredObj = Object.keys(yourObj) .filter(key => allowed.includes(key)) .reduce((obj, key) => { obj[key] = yourObj[key]; return obj; }, {});console.log(filteredObj ); // It will return participants where Finalist is true.

Hope it helps!
