Homework Hacks

Const and Let

%%js 

const name = "Anvay";  // const because the name won't change
let age = 15;          // let because the age might change
const city = "San Diego";
let hobby = "playing video games"; 

console.log("Name: " + name);
console.log("Age: " + age);
console.log("City: " + city);
console.log("Hobby: " + hobby);

/* How did I access the console?

1. I used the console.log() function to print the variables to the console.
2. I used my browser's developer tools (A.K.A "Inspect") to view the console output 
3. I was able to view the log outputs in the "Console" tab of the developer tools

*/

function createSentence() {
    let sentence = `${name} is ${age} years old, lives in ${city}, and enjoys ${hobby}.`;
    
    console.log(sentence);
}

// Call the function to display the final sentence
createSentence();

Average Grade Calculator

%%js 

// Function to calculate the average grade of a student
function calculateAverageGrade(grades) {
    let total = 0;
    for (let i = 0; i < grades.length; i++) { // loops through each grade in the array using index i
        total += grades[i];  // Adds each grade to the total
    }
    // Calculate the average by dividing the total by the number of grades
    let average = total / grades.length;
    return average;
}

// Create an array of students with their info and grades
const students = [
    {
        name: "John",
        age: 15,
        grades: [90, 85, 88]
    },
    {
        name: "Bob",
        age: 16,
        grades: [78, 82, 80]
    },
    {
        name: "Mike",
        age: 14,
        grades: [95, 92, 90]
    }
];

// Loop through each student in the array and calculate their average grade
for (let i = 0; i < students.length; i++) {
    let student = students[i];  // Get each student's info
    let averageGrade = calculateAverageGrade(student.grades);  // Call the function to get average
    student.averageGrade = averageGrade;  // Add average grade to the student dictionary

    // Log the info to console
    console.log(`${student.name}, Age: ${student.age}, Average Grade: ${averageGrade.toFixed(2)}`);
}
