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.

# All the information
The `os` module is a very nifty little module that allows us to get information about the OS. While it has a lot of operating system-related utility methods and properties, we will just look at a few common ones. Run the code below and see if you understand what each output means.

const os = require('os');

console.log("Architecture:", os.arch(), "\n")
console.log("CPUs:", os.cpus(), "\n")
console.log("Network interfaces:", os.networkInterfaces(), "\n")
console.log("Platform:", os.platform(), "\n")
console.log("Release number:", os.release(), "\n")
console.log("User info:", os.userInfo(), "\n")

# Too much information?
Don't feel overwhelmed by everything that was printed in the output; we'll explain everything.

| **Methods** | **Explanation** |
|-|-|
| `os.arch()` | Returns the operating system CPU architecture |
| `os.cpus()` | Returns an array of objects containing information about each logical CPU core |
| `os.networkInterfaces()` | Returns an object containing network interfaces that have been assigned a network address |
| `os.platform()` | Returns a string identifying the operating system platform |
| `os.release()` | Returns a string that identifies the operating system release number |
| `os.userInfo()` | Returns information about the current user |

Depending on how much you have interacted with a similar module in a different language, or perhaps, the command line terminal, these commands may either seem self-explanatory or downright confusing. The purpose of this introductory course is to get you familiarized with the different modules that Node.js has to offer; you may not even use or come across some of these. The `os` module is rarely used, but now you know that it's available if you need it.
