importancia: 5

Escribe la función sortByAge(users) que cree un array de objetos con al propiedad age y los ordene según age.

Por ejemplo:

let john = { name: "John", age: 25 };
let pete = { name: "Pete", age: 30 };
let mary = { name: "Mary", age: 28 };

let arr = [ pete, john, mary ];

sortByAge(arr);

// ahora: [john, mary, pete]
alert(arr[0].name); // John
alert(arr[1].name); // Mary
alert(arr[2].name); // Pete

function sortByAge(arr) {
  arr.sort((a, b) => a.age - b.age);
}

let john = { name: "John", age: 25 };
let pete = { name: "Pete", age: 30 };
let mary = { name: "Mary", age: 28 };

let arr = [ pete, john, mary ];

sortByAge(arr);

// ahora ordenado es: [john, mary, pete]
alert(arr[0].name); // John
alert(arr[1].name); // Mary
alert(arr[2].name); // Pete
