// 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,
firstName: "Mitzi",
gender: "F"
}
const kennan = {
id: 2,
firstName: "Kennan",
gender: "M"
}
const keven = {
id: 3,
firstName: "Keven",
gender: "M"
}
const gannie = {
id: 4,
firstName: "Gannie",
gender: "M"
}
const antonietta = {
id: 5,
firstName: "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["firstName"]);
// Kennan's ID
console.log(kennan["id"]);
// Keven's email
console.log(keven["email"]);
// Gannie's name
console.log(gannie["firstName"]);
// 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 = function() {
return "Hello, my name is " + kennan.firstName + "!";
}
// 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 = function(num1, num2) {
return num1 * num2;
}
// === Great work! === Head over to the the arrays.js file or take a look at the stretch challenge
// ==== 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: function() {
return "My name is " + this.name;
},
child: {
name: "George",
age: 50,
speak: function() {
return "My name is " + this.name;
},
grandchild: {
name: "Sam",
age: 30,
speak: function() {
return "My name is " + 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 + " is " + parent.child.grandchild.age);
// Have the parent speak
console.log(parent.speak());
// Have the child speak
console.log(parent.child.speak());
// Have the grandchild speak
console.log(parent.child.grandchild.speak());
