// 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, [email protected], Mitzi, F
// 2, [email protected], Kennan, M
// 3, [email protected], Keven, M
// 4, [email protected], Gannie, M
// 5, [email protected], Antonietta, F
// Example format of an intern object: 1, [email protected], Example, F
const example = {
id: 0,
name: "Example",
gender: "F",
}
// Write your intern objects here:
const mitzi = {
id: 1,
name: "Mitzi",
gender: "F",
}
const kennan = {
id: 2,
name: "Kennan",
gender: "M",
}
const keven = {
id: 3,
name: "Keven",
gender: "M",
}
const gannie = {
id: 4,
name: "Gannie",
gender: "M",
}
const antonietta = {
id: 5,
name: "Antonietta",
gender: "F",
}
// ==== Challenge 2: Reading Object Data ====
// Once your objects are created, log out the following requests from HR into the console:
// Mitzi's name
console.log(mitzi.name);
// Kennan's ID
console.log(kennan.id);
// Keven's email
console.log(keven.email);
// Gannie's name
console.log(gannie.name);
// Antonietta's Gender
console.log(antonietta.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());
kennan.speak = () => "Hello, my name is Kennan!";
// 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));
antonietta.multiplyNums = (num1, num2) => num1 * num2;
// === Great work! === Head over to the the arrays.js. You may come back and attempt the Stretch Challenge once you have completed the challenges in arrays.js and function-conversion.js.
// ==== Stretch Challenge: Nested Objects and the this keyword ====
// 1. Create a parent object with properties for name and age. Make the name Susan and the age 70.
// 2. Nest a child object in the parent object with name and age as well. The name will be George and the age will be 50.
// 3. Nest a grandchild object in the child object with properties for name and age. The name will be Sam and the age will be 30
// 4. Give each of the objects the ability to speak their names using the this keyword.
const parent = {
name: "Susan",
age: 70,
speak: () => console.log(this.name),
child: {
name: "George",
age: 50,
speak: () => console.log(this.name),
grandchild: {
name: "Sam",
age: 30,
speak: () => console.log(this.name),
}
}
};
// Log the parent object's name
console.log(parent.name);
// Log the child's age
console.log(parent.child.age);
// Log the name and age of the grandchild
console.log(parent.child.grandchild.name);
console.log(parent.child.grandchild.age);
// Have the parent speak
parent.speak();
// Have the child speak
parent.child.speak();
// Have the grandchild speak
parent.child.grandchild.speak();
