Long Practice: Class Syntax with Employees and Managers

Now that you've learned about class syntax, commonJs modules, and reading test specs, it's time to bring these skills together!

In this practice, you will:

1. Create and use JavaScript ES6 classes
2. Use inheritance to create a child of a parent class
3. Use polymorphism to overwrite/override an inherited method
4. Use commonJS modules to import/export your code

Learning Goals

• Understand how a child class inherits from a parent class
• Know when and how to use super and extends
• Know how to override a parent class's method

Introduction

HR has tasked you with building a simple application to keep track of each employees' name, title, salary, and manager. You will also need to keep track of each manager's name, title, salary, their own manager (if they have one), as well as a list of each of employee they manage directly.

You will then need to calculate an employee/manager's individual yearly bonus, taking into account whether they are an employee or a manager.

Project Overview

This project will leverage basic Class syntax to create an Employee class. In a separate file you will create a Manager class that will inherit its properties from the Employee class.

Using common JSmodules to import/export your classes will allow you to keep your code clean and maintainable.

Once you know you can create both an instance of an employee and a manager, you will alter your Employee constructor to dynamically add an Employee to their Manager's employees list upon instantiation.

Finding an Employee's bonus should prove pretty easy, but in order to calculate a Manager's bonus you will need to use iteration and recursion in order to find and sum the salaries of each Employee under that Manager. If an Employee is also a Manager you'll need to sum their Employees' salaries as well.

You will use a combination of local testing and test specs to ensure your application performs as it should.

Set up

Clone the starter from the Download link at the bottom of this page.

Run npm install to install any dependencies.

Phases

• Basic Phase 1: Define an Employee class
• Basic Phase 2: Define a Manager class that extends the Employee class
• Intermediate Phase 3: Dynamically add Employees to a Manager's employee array
• Advanced Phase 4: Calculate Bonuses
• Bonus Phase 5: Local Testing
