// Objective: Learn to create, access, and modify properties of JavaScript objects.

// 1. Create an object named student with properties: name (string), age (number), and grades (array of numbers).

let student = {

name: "Alex",

age: 20,

grades: [88, 76, 92, 85]

};

// 2. Print the student's name and age to the console.

console.log("Student Name: " + student.name + ", Age: " + student.age);

// 3. Add a new property to the student object named "major" and assign it a value of "Computer Science".

student.major = "Computer Science";

// 4. Write a function that calculates and returns the average grade from the grades array.

function calculateAverage(grades) {

let sum = 0;

for (let grade of grades) {

sum += grade;

}

return sum / grades.length;

}

// 5. Call the function with the student's grades and print the average grade to the console.

let averageGrade = calculateAverage(student.grades);

console.log("Average Grade: " + averageGrade);

// Exercise: Try adding more properties and functions to the student object. For instance, add a function to update the student's major.
