getAverageAge(users) funktsiyasini yozing, bu age xususiyatiga ega bo’lgan obyektlar massivini oladi va o’rtacha qiymatni qaytaradi.

O’rtacha son uchun formula (age1 + age2 + ... + ageN) / N.

Misol uchun:

          let john = { name: "John", age: 25 };
let pete = { name: "Pete", age: 30 };
let mary = { name: "Mary", age: 29 };

let arr = [john, pete, mary];

alert(getAverageAge(arr)); // (25 + 30 + 29) / 3 = 28
        

function getAverageAge(users) {
  return users.reduce((prev, user) => prev + user.age, 0) / users.length;
}

let john = { name: "John", age: 25 };
let pete = { name: "Pete", age: 30 };
let mary = { name: "Mary", age: 29 };

let arr = [john, pete, mary];

alert(getAverageAge(arr)); // 28
