Bonus Calculator App

You are going to write a single JavaScript file to automatically calculate employee bonus for a company.

Objectives

  • Practice Read, Write, Speak, Teach skills
  • Solidify JavaScript knowledge
  • Translate business needs to code
  • Practice Group Work

Pair Programming

We'll be pair/trio programming for our first group coding activity.

Video: https://www.youtube.com/watch?v=vgkahOzFH2Q

Note: This is a real world thing, not just a thing kids do or that we use in the classroom. Many people use pair programming on the job.

For remote work, use VSCode Live Share to collaborate on code in pairs.

Key takeaways:

  • Use 1 computer for coding. First driver uses the template. Others can fork from the 1st driver when done so everyone gets the code.
  • Communicate - It should not be quiet in here.
  • Switch roles - one person should not drive for the whole assignment.

Where to Start

This project can seem huge. It is an exercise in figuring out where to start and what SMALL STEPS to take next.

It's often a good idea to "make it work for one thing" before making it work for all the things. In this case, we could work on getting the bonus calculation function working for just one employee before trying to call it multiple times inside of a loop.

Consider starting by getting this function to work only for Atticus.

Data Structure

The company is providing you with a few samples of employee data of how their data is currently being stored. Each are stored in a global array named employees.

Employee Array

Each Employee currently is configured in this way:

  • The name property holds the employee's name.
  • The employeeNumber property has their employee number.
  • The annualSalary property contains their base annual salary.
  • The reviewRating property contains their review rating.

A Loop to Process Bonuses

Loop over the employees array and do the following:

  • use each employee object as the input to the function described below.
  • console.log the results of each iteration.
    • The log should be in the loop, not the function.

The Bonus Calculation Function

Write a declared function that takes in one Employee object (as an argument to the function), and return a new object with the following properties. Note these properties are different than the ones you start with!

  • The name property should contain the employee's name.
  • The bonusPercentage property should contain the bonus percentage the employee is to receive. See section below for calculation instructions.
  • The totalCompensation property should be the adjusted annual compensation (base annual + bonus)
  • The totalBonus should be the employee's total bonus rounded to the nearest dollar.

Individual Bonus Rules

  • Those who have a rating of a 2 or below should not receive a bonus.
  • Those who have a rating of a 3 should receive a base bonus of 4% of their base annual income.
  • Those who have a rating of a 4 should receive a base bonus of 6% of their base annual income.
  • Those who have a rating of a 5 should receive a base bonus of 10% of their base annual income.
  • If their employee number is 4 digits long, this means they have been with the company for longer than 15 years, and should receive an additional 5%.
  • However, if their annual income is greater than $65,000, they should have their bonus adjusted down 1%.
  • No bonus can be above 13% or below 0% total.

Stretch Goals

  • Create a diagram, flowchart, or some other visual aid that documents the logic you've just implemented.
    • The more you practice this skill, the more you become an awesome communicator of algorithmic logic. This is a superpower that you can develop during your time at Prime, but you'll neet to commit to practicing it.
