const array = [];

for(let i = 0; i < 10000; i++) {
	const o = {
		id: generateRandomString(10),
		bbox: [0.47181372549019607, 0.5016339869281046, 0.0718954248366013, 0.08714596949891068],

const map = array.reduce((acc, o) => ({...acc, [o.id]: o}), {});

const indexToRetrieve = parseInt(Math.random() * 10000);
const objectId = array[indexToRetrieve].id;
