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 the `async/await` pattern to perform asynchronous operations.

## Asynchronous programming with `async`/`await`

In the not-so-distant past, developers typically relied on promise chains to handle asynchronous logic, which would quickly lead to messy and unreadable code.

The `async/await` statements greatly simplify the syntax for making asynchronous calls with JavaScript. They make asynchronous code look like synchronous code.

Functions declared with `async` always return a promise, like in the example below:
