Hacks

Create a JavaScript snippet below with the following requirements:

Create an object representing yourself as a person. The object should have keys for your name, age, current classes, interests, and two more of your choosing
Your object must contain keys whose values are arrays. The arrays can be arrays of strings, numbers, or even other objects if you would like
Print the entire object after declaring it
Manipulate the arrays within the object and print the entire object as well as the specific changed key afterwards
Perform mathematical operations on fields in your object such as +, -, /, % etc. and print the results along with a message contextualizing them
Use typeof to determine the types of at least 3 fields in your object

%%js

const person = { // this whole thing is the object
    name: "Brandon So", // my name is a string
    age: 16, // my age is a number
    currentClasses: ["AP CSP", "AP English Language", "AP Physics", "AP Calculus"], 
    interests: ["Programming", "Volleyball", "Working Out"],
    favoriteMovies: ["Avengers Endgame", "Moneyball"],
    hoursOfWorkPerDay: 2,
  };
  
  // Print the entire object
  console.log("Name:", person.name);
  console.log("Age:", person.age);
  console.log("Interests:", person.interests);
  console.log("Classes:", person.currentClasses);
  console.log("Favorite Movies:", person.favoriteMovies);

  
  // Manipulation of the arrays within the object
  person.currentClasses.push("US History");
  person.interests.pop();
  person.favoriteMovies[1] = "The Godfather";
  
  // Print the entire object after manipulation
  console.log("Interests:", person.interests);
  console.log("Classes:", person.currentClasses);
  console.log("Favorite Movies:", person.favoriteMovies);
  console.log("Hours of Homework:", person.hoursOfWorkPerDay);
  
  // Perform mathematical operations on fields
  const totalHoursOfWorkPerWeek = person.hoursOfWorkPerDay * 7;
  const ageInFiveYears = person.age + 5;
  
  // Print results with contextual messages
  console.log("Total hours of work per week:", totalHoursOfWorkPerWeek);
  console.log("Age in five years:", ageInFiveYears);


// Determine the types of 3 fields in my Object
console.log("Name is a", typeof person.name);
console.log("Age is a", typeof person.age);
console.log("Interests is an", typeof person.interests);
