Node.js came as a blessing for JavaScript developers worldwide struggling with swapping among multiple languages and frameworks to amplify their code into a sustainable development environment.

With Node.js, you can finally build web applications with two-way connections where both the server-side and client-side can thoroughly communicate in real-time and exchange data. Indeed, Node.js has been revolutionary for developers who wanted to push real-time web applications over WebSocket.

If you’re aiming forward to enhancing your web development skills to the next level and becoming a full-stack JavaScript developer, Node.js indeed prepares the path towards that enthusiastic buzzword!

In this article, we’ll demonstrate a step-by-step guideline for installing Node.js on your computer and commencing with your web development journey.

What Is Node.js?

The first thing you should know is that Node.js is not a programming language!

You may already be aware of this fact, but it bears repeating for new developers in the field who may mistake Node.js for a unique programming language. It’s not!

Node.js is an open-source runtime environment for the JavaScript language that reshapes JavaScript’s characteristics and upgrades its functionality. As a result, you can use JavaScript for frontend and backend development, enabling full-stack development solely using JavaScript.

Initially, Node.js was designed to serve real-time performance, pushed-back architectures. But since then, Node.js has grown into a vital element for server-side programming for event-driven, non-blocking servers. Most conventional websites and API services today depend on Node.js.

Before Node.js, if you wanted to store any data on the database or connect your program to the database, you needed support from a server-side language. That’s because JavaScript couldn’t regulate the backend process. Consequently, you had to learn server-side languages like PHP, Python, Ruby, or C# — or seek a backend developer’s help.

The Node.js environment empowers JavaScript to directly employ the database and function properly as a backend language. As a result, you can ultimately build and run a program using only JavaScript with Node.js.

Node.js uses the V8 JavaScript runtime engine as its root power, and it employs a non-blocking I/O architecture that’s event-driven. All these together construct Node.js and help drive products towards robust performance.

 

Who Uses Node.js?

According to W3Techs, to date, 1.4% of all websites use Node.js — that’s more than 22 million websites. These numbers give you a general idea of the amount of Node.js users. On top of that, Node.js has been downloaded more than 1.3 billion times! As you can see, the stats speak strongly to Node.js’ market scale.

From your friends in IT to the industry tycoons, all are enjoying leveraging Node.js. That’s because
