// 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:
const mitzi = {
"id": 1,
"email": "mmelloy0 @psu.edu",
"first_name": "Mitzi",
"gender": "F"
}
const kennan =
{
"id": 2,
"first_name": "Kennan",
"gender": "M",
'speak': () => console.log(`hello my name ${kennan.first_name}`)
}
const keven =
{
"id": 3,
"first_name": "Keven",
"gender": "M"
}
const gannie =
{
"id": 4,
"first_name": "Gannie",
"gender": "M"
}
const antonietta =
{
"id": 5,
"first_name": "Antonietta",
"gender": "F",
"multiplyNums": (num1, num2) => {
return num1 * num2;
}
}
// 1,[email protected],Mitzi,F
// 2,[email protected],Kennan,M
// 3,[email protected],Keven,M
// 4,[email protected],Gannie,M
// 5,[email protected],Antonietta,F
// Write your intern objects here:
// ==== Challenge 2: Reading Object Data ====
// Once your objects are created, log out the following requests from HR into the console:
// Mitzi's name
console.log(mitzi.first_name);
// Kennan's ID
console.log(kennan.id);
// Keven's email
console.log(keven.email);
// Gannie's name
console.log(gannie.first_name);
// Antonietta's Gender
console.log(antonietta.gender);
// ==== Challenge 3: Object Methods ====
// Give Kennan the ability to say "Hello, my name is Kennan!" Use the console.log provided as a hint.
kennan.speak();
// Antonietta loves math, give her the ability to multiply two numbers together and return the product. Use the console.log provided as a hint.
console.log(antonietta.multiplyNums(3,4));
// === Great work! === Head over to the the arrays.js file or take a look at the stretch challenge
// ==== Stretch Challenge: Nested Objects and the this keyword ====
// 1. Create a parent object with properties for name and age. Make the name Susan and the age 70.
// 2. Nest a child object in the parent object with name and age as well. The name will be George and the age will be 50.
// 3. Nest a grandchild object in the child object with properties for name and age. The name will be Sam and the age will be 30
// 4. Give each of the objects the ability to speak their names using the this keyword.
const parent = {
"name": "Susan",
"age": 70,
speak: function() {
console.log(`${this.name}`)
},
"child": {
"name": "Georgia",
"age": 50,
speak: function () {
console.log(`${this.name}`)
},
"grandchild": {
"name": "Sam",
"age": 30,
speak: function () {
console.log(`${this.name}`)
},
}
}
}
// Log the parent object's name
parent.speak();
// Log the child's age
// child.speak();
child.speak();
// Log the name and age of the grandchild
// Have the parent speak
// Have the child speak
// Have the grandchild speak
