Как написать функцию, которая отсортирует комментарии в новый объект по двум параметрам?

const data = [
  { name: 'Alice', city: 'Moscow', OS: 'IOS', year: 2014 },
  { name: 'Ivan', city: 'LA', OS: 'IOS', year: 2017 },
  { name: 'Greg', city: 'Yerevan', OS: 'Android', year: 2022 },
];
const result = topicalComments(data);

console.log(result);
// { 
//   Android: 1, 
// }

const data = [
  { name: 'Alice', city: 'Moscow', OS: 'IOS', year: 2014 },
  { name: 'Ivan', city: 'LA', OS: 'IOS', year: 2017 },
  { name: 'Greg', city: 'Yerevan', OS: 'Android', year: 2022 },
];
const result = topicalComments(data);
console.log(result)
 
function topicalComments(arr) {
    return arr.reduce((o, e) => {
        if (e.year >= 2022) o[e.OS] = o[e.OS] ?? 0 + 1
        return o
    }, {})
}
