WorkAround Explorer

Before I reach step 8 of the project, my output looks like this.


However, once I complete step 8 and step 9, the output goes back to what it was at the start of the project, and it looks like this.


The code snippets below contain my code.

Code in Main.js

// TODO: Add your import statements here.
import {getRoles, getCompanies} from './modules/salaryData.js'
import {getAverageSalaryByRole, getAverageSalaryByCompany, getSalaryAtCompany, getIndustryAverageSalary} from './modules/workAroundModule.js'
// TODO: Get the companies and roles using the salaryData module.
const companies = getCompanies();
const roles = getRoles();

// Create input buttons for every company and role represented in the data.
renderInputButtons(companies, 'company');
renderInputButtons(roles, 'role');

// This function will create a new <section> with radio
// inputs based on the data provided in the labels array.
function renderInputButtons(labels, groupName) {
  const container = document.createElement('section');
  container.setAttribute('id', `${groupName}Inputs`);

  let header = document.createElement('h3');
  header.innerText = `Select a ${groupName}`;

  labels.forEach(label => { // For each label...
    // Create the radio input element.
    let divElement = document.createElement('div');
    divElement.setAttribute('class', 'option');

    let inputElement = document.createElement('input');
    inputElement.setAttribute('type', 'radio');
    inputElement.setAttribute('name', groupName);
    inputElement.setAttribute('value', label);

    // Create a label for that radio input element.
    let labelElement = document.createElement('label');
    labelElement.setAttribute('for', label);
    labelElement.innerText = label;

    // Update the results when the input is selected.
    inputElement.addEventListener('click', updateResults);



function updateResults(){
  // Get the current selected company and role from the radio button inputs.
  const company = document.querySelector("input[name='company']:checked").value;
  const role = document.querySelector("input[name='role']:checked").value;

  // If either the company or role is unselected, return.
  if (!company || !role) { return; }

  // TODO: Use the workAroundModule functions to calculate the needed data.
  const averageSalaryByRole = getAverageSalaryByRole(role);
  const averageSalaryByCompany = getAverageSalaryByCompany(company);
  const salary = getSalaryAtCompany(role, company);
  const industryAverageSalary = getIndustryAverageSalary();

  // Render them to the screen.
  document.getElementById('salarySelected').innerText = `The salary for ${role}s at ${company} is \$${salary}`;
  document.getElementById('salaryAverageByRole').innerText = `The industry average salary for ${role} positions is \$${averageSalaryByRole}`;
  document.getElementById('salaryAverageByCompany').innerText = `The average salary at ${company} is \$${averageSalaryByCompany}`;
  document.getElementById('salaryAverageIndustry').innerText = `The average salary in the Tech industry is \$${industryAverageSalary}`;

Code in workAroundModule.js

// Add your imports here.

// Replace the empty array with the appropriate imported function/value

  const companyData = getDataByCompany();
  const roleAtCompany = companyData.find(obj => obj.role === role);
  return roleAtCompany.salary;

// Replace the empty array with the appropriate imported function/value
const getIndustryAverageSalary = () => {
  const allSalaries = => obj.salary);
  return calculateAverage(allSalaries);

// Helper Function. Do not edit.
// Note: This function does not need to be exported since it is only used by the functions contained within this module.
function calculateAverage(arrayOfNumbers) {
  let total = 0;
  arrayOfNumbers.forEach(number => total += number);
  return (total / arrayOfNumbers.length).toFixed(2);

export {getAverageSalaryByRole, getAverageSalaryByCompany, getSalaryAtCompany, getIndustryAverageSalary};

Code in salaryData.js

const salaryData = [
  { role: 'CTO', company: 'Big Data Inc.', salary: 320000},
  { role: 'Technical Lead', company: 'Big Data Inc.', salary: 230000},
  { role: 'Software Engineer II', company: 'Big Data Inc.', salary: 180000},
  { role: 'Software Engineer I', company: 'Big Data Inc.', salary: 140000},
  { role: 'CTO', company: 'Medium Data Inc.', salary: 215000},
  { role: 'Technical Lead', company: 'Medium Data Inc.', salary: 165000},
  { role: 'Software Engineer II', company: 'Medium Data Inc.', salary: 140000},
  { role: 'Software Engineer I', company: 'Medium Data Inc.', salary: 115000},
  { role: 'CTO', company: 'Small Data Inc.', salary: 175000},
  { role: 'Technical Lead', company: 'Small Data Inc.', salary: 135000},
  { role: 'Software Engineer II', company: 'Small Data Inc.', salary: 115000},
  { role: 'Software Engineer I', company: 'Small Data Inc.', salary: 95000},

const getRoles = () => {
  return ['CTO', 'Technical Lead', 'Software Engineer II', 'Software Engineer I'];

const getCompanies = () => {
  return ['Big Data Inc.', 'Medium Data Inc.', 'Small Data Inc.'];

const getDataByRole = role => {
  return salaryData.filter(obj => obj.role === role);

const getDataByCompany = company => {
  return salaryData.filter(obj => === company);

export {getRoles, getCompanies, getDataByRole, getDataByCompany};

export default salaryData;

How do I fix this? Is there an issue in my code?

you seem to be missing arguments for some functions:

in the function getAverageSalaryByRole
const roleData = getDataByRole();
should be
const roleData = getDataByRole(role);

similarly, in the function getAverageSalaryByCompany and in the function getSalaryAtCompany
const companyData = getDataByCompany();
should be
const companyData = getDataByCompany(company);

I don’t know if that will help.

Thank you so much! It worked!
