You can use for-of loop

let users = [
{
    firstName: "John",
    lastName: "Doe",
    age: 34
},
{
    firstName: "Jack",
    lastName: "Jackson",
    age: 23
},
{
    firstName: "Ann",
    lastName: "Watson",
    age: 24
}
];
function getUsers(users) {
    for (var user of users) {
         console.log(user.firstName + " is " + user.age + " years old!");
    }
}

getUsers(users);
