Using an Imported Number Formatting Module on a Function in Another File

[northernwoolley]

Hi guys,

I have created a function in a file called utilities.js as below

const formatNumber = (number) => {
  return number.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}

export default formatNumber;

And I am trying to use this (as an imported module) to render the results of the below functions.

// TODO: Add your import statements here.
import {getRoles,getCompanies} from './modules/salaryData.js';

import {getAverageSalaryByRole, getAverageSalaryByCompany, getSalaryAtCompany,getIndustryAverageSalary} from './modules/workAroundModule.js';

import formatNumber from "/modules/utilities.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}`;
  container.appendChild(header);

  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);
    divElement.appendChild(inputElement);

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

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

    container.appendChild(divElement);
  });

  document.querySelector('main').prepend(container);
}

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}`;
}

How to I change the output of the above functions under " // Render them to the screen." to use the format in my utilities.js function?

Just in case anyone else needs help, I worked it out. I changed the

const averageSalaryByRole = getAverageSalaryByRole(role);
const averageSalaryByCompany = getAverageSalaryByCompany(company);
const salary = getSalaryAtCompany(role, company);
const industryAverageSalary = getIndustryAverageSalary();

to

const averageSalaryByRole = formatNumber(getAverageSalaryByRole(role));
const averageSalaryByCompany = formatNumber(getAverageSalaryByCompany(company));
const salary = formatNumber(getSalaryAtCompany(role, company));
const industryAverageSalary = formatNumber(getIndustryAverageSalary());
