Object-Oriented JavaScript

Working with Object Literals

Challenge 1
Create a function that has two parameters (name and age) and returns an object. Let's call this function makePerson. This function will:
1. Create an empty object
2. Add a name property to the newly created object with its value being the 'name' argument passed into the function
3. Add an age property to the newly created object with its value being the 'age' argument passed into the function
4. Return the object

Using Object.create

Challenge 2
Inside personStore object, create a property greet where the value is a function that logs "hello".
Challenge 3
Create a function personFromPersonStore that takes as input a name and an age. When called, the function will create person objects using the Object.create method on the personStore object.
Challenge 4
Without editing the code you've already written, add an introduce method to the personStore object that logs "Hi, my name is [name]".

Using the NEW keyword

Challenge 5
Create a function PersonConstructor that uses the this keyword to save a single property onto its scope called greet. greet should be a function that logs the string 'hello'.
Challenge 6
Create a function personFromConstructor that takes as input a name and an age. When called, the function will create person objects using the new keyword instead of the Object.create method.
Challenge 7
Without editing the code you've already written, add an introduce method to the PersonConstructor function that logs "Hi, my name is [name]".

Using ES6 Classes

Challenge 8
Create a class PersonClass. PersonClass should have a constructor that is passed an input of name and saves it to a property by the same name. PersonClass should also have a method called greet that logs the string 'hello'.
Challenge 9
Create a class DeveloperClass that creates objects by extending the PersonClass class. In addition to having a name property and greet method, DeveloperClass should have an introduce method. When called, introduce should log the string 'Hello World, my name is [name]'.
EXTENSION: Subclassing
Classes in JavaScript can also inherit properties from other classes - this phenomena is known as subclassing. If you've finished all the main challenges, we encourage you to do some research on this concept and complete the challenges below!
Challenge 10
Create an object adminFunctionStore that has access to all methods in the userFunctionStore object, without copying them over individually.
Challenge 11
Create an adminFactory function that creates an object with all the same data fields (and default values) as objects of the userFactory class, but without copying each data field individually.
Challenge 12
Then make sure the value of the 'type' field for adminFactory objects is 'Admin' instead of 'User'.
Challenge 13
Make sure that adminFactory objects have access to adminFunctionStore methods, without copying them over.
Challenge 14
Created a method called sharePublicMessage that logs 'Welcome users!' and will be available to adminFactory objects, but not userFactory objects. Do not add this method directly in the adminFactory function.
EXTENSION: Mixins
Mixins are a tool in object-oriented programming that allows objects to be given methods and properties beyond those provided by their inheritance. For this challenge, complete the missing code, giving all of the robotMixin properties to robotFido. Do this in a single line of code, without adding the properties individually.
