JavaScript popcorn hacks

Hack #1

%%js

// Step 1: Create a set called Set1 of 3 numbers
let Set1 = new Set([1, 2, 3]);

// Step 2: Create a set called Set2 of different 3 numbers
let Set2 = new Set([4, 5, 6]);

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

// Step 3: Add a number to Set1 and remove the 1st number (1 in this case)
Set1.add(7);
Set1.delete(1);

// Log the updated Set1
console.log("Updated Set1:", Set1);

// Step 4: Log the union of both Set1 and Set2
let unionSet = new Set([...Set1, ...Set2]);
console.log("Union of Set1 and Set2:", unionSet);

Hack #2

%%js

// Step 1: Create a Dictionary called "application"
let application = {
    name: "Alice Smith",
    age: 28,
    experiences: ["Software Developer", "Project Manager", "UX Designer"],
    money: 1500
};

// Step 2: Log the dictionary to make sure it works
console.log("Application Dictionary:", application);

// Step 3: Log only the dictionary's money
console.log("Money:", application.money);
