JS Object Oriented Programming

Getting Started

Fork and clone this repository
npm install in this directory

Overview

In this exercise, you will practice the principles object oriented programming to create a school system. There are 32 automated tests that you have to pass. You will also utilize the concept of inheritance to create a blueprint for several schools. You should be running the tests after each step with npm test.

Instructions

You will be writing all of your code in the index.js file. The class names have already been provided for you. You will be adding logic to the class definitions in this file

Step 1

In the School class:

set up a constructor that accepts schoolName and level parameters.
store these parameters in the constructor as class properties.
set up a property called students and set it equal to an empty array.
create an enrollStudent method. It should accept a student as a parameter.
create a method called listEnrollmentNumbers. This method will not accept any parameters.

Step 2

In the High class:

inherit from the School class:
- Make sure to call super in the constructor.
Add a name parameter to the constructor.
Pass the name and hard code in a level in the super method. (Order matters, name should go first)
create a property called sportsTeams. Set this to an empty array.
create a method called addTeam, this should have a parameter of team

Step 3

In the Middle class:

inherit from the School class
set up a constructor that accepts name as an argument
make sure to call super in the constructor
pass the name parameter to super and hard code value for the level parameter. (Order Matters)

Step 4

In the Primary class:

inherit from the School class
set up a constructor that accepts name and pickUpPolicy parameters
- make sure to call super in the constructor
- pass the name parameter to super and hard code a value for the level parameter. (Order Matters)
store the pickUpPolicy as a class property and set it to the pickUpPolicy argument
create a method called listPickUpPolicy

Step 5

In the Student class:

accept name and email as arguments in the constructor
store these as class properties

Step 6

Back in the School class:

The enrollStudent method should add a student to our students array.
listEnrollmentNumbers should return the number of students in our students array.

Step 7

Back in the High class:

the addTeam method should add a team to our sportsTeams array.

Step 8

Back in the Primary class:

listPickUpPolicy should return the following string: You must pick up your child at <pickUpPolicy>!. Make sure to replace the contents in <> with your pickup policy property. Make sure to remove the <>!

Step 9

In the SportsTeam class:

set up a constructor with a name, sport and numOfPlayers property. These should be provided in the constructor arguments

Step 10

Once all 32 tests have passed, open the playground.js file. Here you'll find:

const { High, Middle, Primary, SportsTeam, Student } = require('.')

The classes you've built have been loaded into this file for you. DO NOT MODIFY LINE 1.

Create an instance of the High class.
Create 5 new students with the Student class.
Add the 5 students to the students property in the instance of the High class. *We inherited from the School class which means we have access to the enrollStudent method.
Create 2 new sports teams. Add these to the instance of the High class you created utilzing the addTeam method.
console.log your instance of the High class.
Run the playground.js file with node playground.js in your terminal.

Additional Practice

Using the playground.js file, create a few more instances of the Middle, Primary and Student classes. Try mixing and matching which school the students are enrolled in.
