];

const divisions = {

};

try {
    const goldUsers = getUsersInDivision(users, division: 'Gold');
    console.log(goldUsers);
    // Output: [{ id: 1, rating: 1500 }]

    const silverUsers = getUsersInDivision(users, division: 'Silver');

It ensures robust error handling, including validation that each user object in users has a rating property, to maintain reliability and consistency in usage.
