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.

# Debug applications

Many developers use `console.log` to debug their Node.js applications. This technique is great for dumping a variable to the terminal so we can check its value or figure out what order our code is running in. However, it isn’t the best option.

Using `console.log` to debug our code generally slows down the development process. This is because we have to repeatedly stop our application, insert a `console.log`, and start our application again. Also, it complicates the debugging process since we’re trying to log out the values we’re debugging amidst the noise of other logging operations

## Debug with an integrated development environment (IDE)

VSCode makes it easy to start a debugging environment for our Node.js application. Let’s take a look at an example.
1. In our `script.js` file, add the following code:
