// 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
let example = {
id: 0,
name: 'Example',
gender: 'F',
};
let interns = [{
"id": 1,
"name": 'Mitzi',
"gender": 'F',
},
{
"id": 2,
"name": 'Kennan',
"gender": 'M',
"speak": () => `Hello my name is ${interns[1].name}!`
},
{
"id": 3,
"name": 'Keven',
"gender": 'M',
},
{
"id": 4,
"name": 'Gannie',
"gender": 'M',
},
{
"id": 5,
"name": 'Antonietta',
"gender": 'F',
"multiplyNums": (x, y) => x * y
}
];
// 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(interns[0].name);
// Kennan's ID
console.log(interns[1].id);
// Keven's email
console.log(interns[2].email);
// Gannie's name
console.log(interns[3].name);
// Antonietta's Gender
console.log(interns[4].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(interns[1].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(interns[4].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.
let parent = {
name: 'Susan',
age: 70,
speak: () => `My name is ${parent.name}!`,
child: {
name: 'George',
age: 50,
speak: () => `My name is ${parent.child.name}!`,
grandchild: {
name: 'Sam',
age: 30,
speak: () => `My name is ${parent.child.grandchild.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, 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());
