JavaScript ES6 Modules

Modules in JavaScript allow code to be organized into separate files. This promotes reusability, maintainability, and clarity. ES6 introduced import and export statements for handling modules.

Use the export keyword to export variables/functions/classes from one file and import to use them in another.

You can export multiple items from a file and import them all at once.

You can export classes alongside variables and functions.

Instead of exporting each item individually, you can export them together at the end.

Use * as alias to import everything into a namespace-like object.

You can have one default export per module. Useful for exporting single functions or classes.

You can export both default and named values from the same file.
