1. Objects

An object in JavaScript is a collection of key-value pairs, where each key is a string and each value can be any valid JavaScript data type, including another object.

Example: Creating an Object

let user = {
    name: "Anshuman",
    age: 19
    // key:value,
};

console.log("Anshuman's age is " + user.age);

Assignments:

1️⃣ Write a function that takes a user object as input and greets them with their name and age.

2️⃣ Write a function that takes an object with name, age, and gender, and greets the user accordingly.

(Example: "Hi Mr./Mrs./Others Anshuman, your age is 21")

3️⃣ Modify the function to also tell the user if they are legally allowed to vote (age > 18).

2. Arrays

Arrays allow you to group multiple values together.

Example: Creating an Array

const users = ["Anshuman", "Raman", "Diljeet"];
const totalUsers = users.length;
const firstUser = users[0];

console.log("Total users:", totalUsers);
console.log("First user:", firstUser);

Assignment:

1️⃣ Create an array of objects, where each object contains name and age.
