Javascript Popcorn Hacks

Popcorn Hack 1 (SETS):

// Create a set called Set1 of 3 numbers
const Set1 = new Set([1, 2, 3]); // You can choose any numbers

// Create a set called Set2 of different 3 numbers
const Set2 = new Set([4, 5, 6]); // Choose different numbers from Set1

// Log both sets separately
console.log("Set1:", Array.from(Set1));
console.log("Set2:", Array.from(Set2));

// Add a number to Set1
Set1.add(7); // Adding the number 7 to Set1
console.log("Set1 after adding 7:", Array.from(Set1));

// Remove the 1st number from Set1 (in this case, we remove the number 1)
Set1.delete(1); // Removing the number 1 from Set1
console.log("Set1 after removing 1:", Array.from(Set1));

// Log the union of both Set1 and Set2
const unionSet = new Set([...Set1, ...Set2]); // Create a union of both sets
console.log("Union of Set1 and Set2:", Array.from(unionSet));

// Create a Dictionary called "application"
const application = {
    name: "Ruhee Banthia",        // Name of the person
    age: 15,                 // Age of the person
    experiences: [           // Array of experiences
        "Influencer",
        "Veternarian",
        "Swimmer"
    ],
    money: 150000000             // Amount of money
};

// Log the dictionary to make sure it works
console.log("Application Dictionary:", application);

// Log only the dictionary’s money
console.log("Money:", application.money);

Homework Hacks

// Function to gather applicant information
function gatherApplicantInfo() {
    // Create an empty dictionary (object) to store applicant information
    const applicant = {};

    // Ask for the applicant's name
    applicant.name = prompt("What is your name?");
    
    // Ask for the applicant's age
    applicant.age = prompt("What is your age?");
    
    // Ask for the applicant's experiences
    const experiences = [];
    let experience;
    
    // Keep asking for experiences until the user types "done"
    while (true) {
        experience = prompt("Enter an experience (or type 'done' to finish):");
        if (experience.toLowerCase() === 'done') {
            break;  // Exit the loop if the user types 'done'
        }
        experiences.push(experience);  // Add the experience to the array
    }
    applicant.experiences = experiences; // Store the experiences in the dictionary

    // Log the user's input
