Where as with Named Exports, you can export certain members of a module,
export default allows you to export a "default" scope of code without having to name it explicitly
in your import. With the right structure, you can also use export default and export a whole object
with many functions as properties.
It's basically saying "export this thing as the default and the import doesn't need to know the real name".
// in theory, HelloWorld1 is the one that doesn't have to be explicitly named with the import.
const HelloWorld1 = () => { console.log(`Hello World 1`); };
const HelloWorld2 = () => { console.log(`Hello World 2`); };
const HelloWorld3 = () => { console.log(`Hello World 3`); };
export { HelloWorld1 as default, HelloWorld2, HelloWorld3 };
You can also use export default like so:
const HelloWorld1 = () => { console.log(`Hello World 1`); };
export { HelloWorld1 as default};
The import might look like:
import hw1 from 'GreetingsDefaultExport.js';
import {HelloWorld2, HelloWorld3} from './GreetingsDefaultExport.js';
