"without touching the module, implement it so that the user can interact with it"... I'm stumped.

I've built an inventory management app in the console, but it didn't use a module, so it's made it very confusing for me. Posting some of the code as it's too long.

var inventory = [];

function clone(obj) {
  return JSON.parse(JSON.stringify(obj));
}

/**
 * @typedef {Object} Product
 * @property {string} name
 * @property {int} count
 */

/**
 *
 * @returns {Array<Product>}
 */
function getInventory() {
  return clone(inventory);
}

/**
 * Gets a product by name
 * @param {string} name
 * @returns {Product}
 */
function getProduct(name) {
  let product = inventory.find((p) => p.name == name);
  if (product == null || product == undefined) {
    throw new Error("Product does not exist");
  }
  return clone(product);
}

/**
 * Add product with initial supply/count
 * @param {string} productName
 * @param {int} count
 */
function addProduct(productName, count) {
  inventory.push({ name: productName, count });
}

var inventory = [];

function clone(obj) {
  return JSON.parse(JSON.stringify(obj));
}

/**
 * @typedef {Object} Product
 * @property {string} name
 * @property {int} count
 */

/**
 *
 * @returns {Array<Product>}
 */
function getInventory() {
  return clone(inventory);
}

/**
 * Gets a product by name
 * @param {string} name
 * @returns {Product}
 */
function getProduct(name) {
  let product = inventory.find((p) => p.name == name);
  if (product == null || product == undefined) {
    throw new Error("Product does not exist");
  }
  return clone(product);
}

/**
 * Add product with initial supply/count
 * @param {string} productName
 * @param {int} count
 */
function addProduct(productName, count) {
  inventory.push({ name: productName, count });
}

App.js

var fs = require("fs");
const prompt = require("prompt-sync")({ sigint: true });

import {
  getInventory,
  addProduct,
  getProduct,
  modifyProductCount,
  removeProduct,
} from "./inventoryManagement.js";
getInventory();

//Without touching a single line of code from step 1, implement this module in a console app that the user can interface with.

const addItem = () => {
  
}

var fs = require("fs");
const prompt = require("prompt-sync")({ sigint: true });

import {
  getInventory,
  addProduct,
  getProduct,
  modifyProductCount,
  removeProduct,
} from "./inventoryManagement.js";
getInventory();

//Without touching a single line of code from step 1, implement this module in a console app that the user can interface with.

const addItem = () => {
  
}

that first code block is not a module, it doesn't have any export or import statement... and I'm not sure what you want to do

it's a snippet, sorry the entire thing is too long without nitro lol https://jsfiddle.net/vwaxoer6/ the entire thing is here I have to implement the module into a console app that the user can interact with, so add/remove/view products I've built one before but not with module importing..

//Add item to inventory
const addItem = () => {
  let Item = prompt("Enter the name of the item you wish to add: ");
  let Name = Item.toLowerCase();
  let Quantity = parseInt(prompt("Now enter the quantity: "));
  inventory.push({ Name, Quantity });
  saveCurrentInventoryToFile();
  console.log(`${Name} added succesfully!`);
};

//Add item to inventory

  let Quantity = parseInt(prompt("Now enter the quantity: "));
  inventory.push({ Name, Quantity });
  saveCurrentInventoryToFile();
  console.log(`${Name} added succesfully!`);
};

would that not work?

import * as ProductManagment from "./inventoryManagement.js";

window.productManagement = ProductManagement;

import * as ProductManagment from "./inventoryManagement.js";

window.productManagement = ProductManagement;
