Script Preparation code:

var items = { ...Array.from(Array(10000).keys()) };
var itemsToFilter = Array.from(Array(10000).keys()).filter(v => v % 2 === 0);

Tests:

Object.fromEntries
var filteredObject = Object.entries(items).filter(([key]) => itemsToFilter.includes(key)); Object.fromEntries(filteredObject);
Object.keys + reduce
Object.keys(items).reduce((acc, key) => { if (itemsToFilter.includes(key)) { acc[key] = items[key]; } return acc; }, {});
Object.entries + reduce
Object.entries(items).reduce((acc, [key, entry]) => { if (itemsToFilter.includes(key)) { acc[key] = entry; } return acc; }, {});
