Can't Complete the JavaScript Module project: WorkAroundExplorer

I can’t complete the project the way it was intended. Here’s my code:

//salaryData.js

<button>
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 => obj.company === company);
}






export { getRoles, getCompanies, getDataByRole, getDataByCompany };

export default salaryData;



//workAroundModule.js

// Add your imports here.
import {getDataByRole, getDataByCompany} from './salaryData.js';

import salaryData from './salaryData.js';

// Replace the empty array with the appropriate imported function/value
const getAverageSalaryByRole = role => {
 const roleData = getDataByRole(role);
 const salariesOfRole = roleData.map(obj => obj.salary);
 return calculateAverage(salariesOfRole);
}

// Replace the empty array with the appropriate imported function/value
const getAverageSalaryByCompany = company => {
 const companyData = getDataByCompany(company);
 const salariesAtCompany = companyData.map(obj => obj.salary);
 return calculateAverage(salariesAtCompany);
}

// Replace the empty array with the appropriate imported function/value
const getSalaryAtCompany = (role, company) => {
 const companyData = getDataByCompany(company);
 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 = salaryData.map(obj => 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};




//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}`;
 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}`;

import { getDataByRole(role), getDataByCompany(company), getDataByCompany(company), salaryData } from './modules/workAroundModule.js';




//index.html

</button>

In your index.html there is a button tag after the closing html tag. It seems to be the problem.
Also, looking at the provided code there is a import made in the last line of main.js that shouldn’t be there:

import { getDataByRole(role), getDataByCompany(company), getDataByCompany(company), salaryData } from './modules/workAroundModule.js';

And finally, in the salarydata.js there is a button html tag in the top of the file.

Since the button tags looks like a typo in the copy paste to make this post, I encourage you to look at the wrong import I mentioned.
