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 with console.log after declaring it
Manipulate the arrays within the object and print the entire object with console.log as well as the specific changed key afterwards
[X]Perform mathematical operations on fields in your object such as +, -, /, % etc. and print the results with console.log along with a message contextualizing them
Use typeof to determine the types of at least 3 fields in your object

%%js
// This defines the variable under which all the information is typed in

const personObject = {
