Built on Chrome’s V8 JavaScript engine, Node.js is a runtime environment that enables JavaScript to run outside the browser. This course will help you learn the fundamentals of Node.js to build portable applications.

You’ll learn about the components and build patterns of Node.js. You’ll also explore the API to learn how to create modules and write code to unique data files. Moreover, you’ll delve into the features and practices of JavaScript and build a REST API using the Express framework from scratch. This will set up authentication tokens with Passport.js and JSON web tokens, and finally build a live trivia game with Socket.IO.

By the end of this course, you’ll be equipped with the extensive knowledge to build rich and comprehensive Node.js applications running on the server with JavaScript.

Learn Node.js from Scratch

By the end of this lesson, we'll be able to apply ES6 modules to modularize our scripts.

## Modules

> **Note:** This lesson uses [CommonJS](https://requirejs.org/docs/commonjs.html) modules throughout.

Modules allow developers to organize their codebase within separate files or components for better reusability, flexibility, shareability, and overall maintenance. Multiple modules can be composed together to create an application.

ECMAScript modules, which are a newer feature in JavaScript, are defined with the use of the `import` and `export` keywords.

Although ECMAScript modules are the official standard format to package JavaScript code, they’re still considered an experimental Node.js feature as of July 2020. This is because the Node.js team is still working on ensuring backward compatibility and support for both module systems.

CommonJS, which is the legacy system, uses the `module.exports` syntax for exports and the `require()` function for imports:
