Answer 1

Part 1

let person1 = {firstName: "Mike", lastName: "Malhotra", exchange: 555, phoneNumber: 942487};
let person2 = {firstName: "Sam", lastName: "Sheikh", exchange: 555, phoneNumber: 987234};
let person3 = {firstName: "Andrew", lastName: "Arya", exchange: 555, phoneNumber: 789732};

Part 2

personArray = [];

function createObject(firstName, lastName, exchange, phoneNumber) {
    let person = {
        firstName: firstName,
        lastName: lastName,
        exchange: exchange,
        phoneNumber: phoneNumber
    };
    personArray.push(person);
}


let firstNames = ["Mike", "Sam", "Andrew"];
let lastNames = ["Malhotra", "Sheikh", "Arya"];
let exchange = 555;
let phoneNumbers = [942487, 908724, 789234];

let i;
for (i = 0; i < firstNames.length; i++) {
    createObject(firstNames[i], lastNames[i], exchange, phoneNumbers[i]);
}

for (i = 0; i < firstNames.length; i++) {
    console.log(personArray[i].firstName + " " + personArray[i].lastName + " " + personArray[i].exchange + " " + personArray[i].phoneNumber);
}

Output
