Modules in JavaScript

 //    The following would be in a file named force-duel.js in the 'modules' folder inside the 'js' folder        
 const anakin = {
     name: 'Anakin',
     power: 10
 }
 const dooku = {
     name: 'Count Dooku',
     power: 7
 }
 export function fight(char1, char2) {
     const attack1 = Math.floor(Math.random() * char1.power);
     const attack2 = Math.floor(Math.random() * char2.power);
     return attack1 > attack2 ? `${char1.name} wins` : `${char2.name} wins`
 }


 //    The following would be in the main script.js (or any other JS)
 import {
     fight
 } from 'js/modules/force-duel.js';

 //    now you can call the imported function
 console.log(fight(char1, char2));


 //    If you are importing to the main index.html, you need to specify type = "module"

<script type = "module" >
 import {
     fight
 } from 'modules/force-duel.js';

 //    now you can call the imported function
 console.log(fight(char1, char2));
 </script>
