It is possible to export named items directly. Consider the following file, atlas.js:

import { launchSequence } from './launch-sequence.js'; 
 
const name = 'Atlas'; 
const COUNT_DOWN_DURATION = 20; 
 
export const atlas = { 
  name: name, 
  COUNT_DOWN_DURATION: COUNT_DOWN_DURATION, 
  launch: function () { 
    launchSequence(COUNT_DOWN_DURATION, name); 
  } 
}; 

The atlas member can be exported directly by index.js:

import * as falconHeavy from './falcon-heavy.js'; 
import * as saturnV from './saturn-v.js'; 
 
export { falconHeavy, saturnV }; 
export { atlas } from './atlas.js';

Then the main.js file can import the atlas member and launch it:

import { atlas, falconHeavy, saturnV } from './rockets/index.js' 
 
export function main () { 
  saturnV.launch(); 
  falconHeavy.launch(); 
  atlas.launch(); 
} 

This is one benefit of always using named exports; it's easier to collect and export specific members from packages with multiple modules.

Whether named or not, nesting is a great technique for grouping modules. It provides a mechanism for organizing code as the number of modules continues to grow.
