// Let's get some practice writing a few objects for a new group of interns at a small business.

// ==== Challenge 1: Writing Objects ====
// HR needs some information on the new interns put into a database. Given an id, email, first name, and gender. Create an object for each person in the company list:

// 1, mmelloy0@psu.edu, Mitzi, F
// 2, kdiben1@tinypic.com, Kennan, M
// 3, kmummery2@wikimedia.org, Keven, M
// 4, gmartinson3@illinois.edu, Gannie, M
// 5, adaine5@samsung.com, Antonietta, F

// Example format of an intern object: 1, examples@you.edu, Example, F
const example = {
id: 0,
name: "Example",
email: "examples@you.edu",
gender: "M",
}

// Write your intern objects here:


// ==== Challenge 2: Reading Object Data ====
// Once your objects are created, log out the following requests from HR into the console:

// Mitzi's name

// Kennan's ID

// Keven's email

// Gannie's name

// Antonietta's Gender

// ==== Challenge 3: Object Methods ====
// Give Kennan the ability to say "Hello, my name is Kennan!" Use the console.log provided as a hint.
// console.log(kennan.speak());

// Antonietta loves math, give her the ability to multiply two numbers together and return the product. Use the console.log provided as a hint.
//console.log(antonietta.multiplyNums(3,4));
