Exporting with export and export default

Understanding how to export values from a module is essential when working with ES Modules in Node.js. ES Modules use the export and export default keywords to make variables, functions, or classes available to other files.

Named exports allow you to export multiple values from a module by name. Each exported value must be explicitly specified, and when importing, you must use the exact exported names.

In contrast, default exports allow you to export a single value as the main exported entity from a module. When importing a default export, you can use any name you choose for the imported value.
