Node.js is an open-source, cross-platform, JavaScript runtime environment that executes JavaScript code outside of a web browser. This course is your guide for learning the fundamentals of Node.js.

In this course, you'll start by understanding the inner workings of Node.js. More specifically, you’ll explore its features, how event loops work, and how multithreading works. You’ll then move on to the fundamentals of Node.js like file systems, global objects, and the Buffer class.

In the latter half of the course, you’ll explore more advanced concepts like modules,  events,  and packages. At the end of this course, you will get hands-on with Node.js and create your own food delivery web application.

By the end of this course, you will have a new, in-demand skill to put on your resume and a cool project to add to your portfolio.

# Debugging made easy
In this lesson, we shall look at a few different functionalities that this module provides.

The console module that Node.js provides is similar to the JavaScript console that most browsers provide. In case you had not noticed, we were not importing the `console` module before using `console.log`. The reason we were not importing anything is that there is a global `console` instance that is configured to write to `process.stdout` and `process.stderr`. Let's look at some of the options that the global `console` provides.

console.log('Hello World');

console.warn('This is a warning!');

console.error('This is an error');

console.error(new Error('This is a different error'));

You can notice that both the `console.warn` and `console.error` have their output in a red box. Educative's code widget uses that to represent an error. Furthermore, we have two `console.errors`: one on **line 5** and another on **line 7**. We pass the second `console.error`, an **`Error`** object with a string instead of just a string, which is why we get a `trace` as well.

> **Error** objects capture a *stack trace*, which points to where the Error was instantiated in the code.

These `console` methods can help track down bugs and problems with code.
