const launches = new Map();
const launch = {
  flightNumber: 100,
  mission: "Kepler Exploration X",
  rocket: "Explorer IS1",
  launchDate: new Date("December 27,2030"),
  destination: "Kepler-442 b",
  customer: ["ZTM", "NASA"],
  upcoming: true,
  success: true,

console.log(launches);
module.export = {

[Map Iterator] {
  {
    flightNumber: 100,

TypeError: Cannot read properties of undefined (reading 'values')

Answer 1

edit module.export to module.exports

module.exports = { launches } // not module.export
