Node JS Tutorial – Lesson One – Somali

If you’re interested in web development or are already a web developer, you may have heard of Node.js. It is a powerful JavaScript runtime that allows you to build scalable web applications and servers. In this tutorial series, we will dive into the basics of Node.js and learn how to create your own applications using this popular technology.

Lesson One: Introduction to Node.js

In this first lesson, we will lay the foundation for our Node.js learning journey. We will start by understanding what Node.js is and why it is gaining so much popularity among web developers.

What is Node.js?

Node.js is an open-source, server-side JavaScript runtime built on Chrome’s V8 JavaScript engine. It allows developers to run JavaScript code outside of a web browser, making it possible to execute JavaScript on the server side. This means that developers can use JavaScript to build powerful and scalable web applications.

Why choose Node.js?

One of the main reasons why developers choose Node.js is its ability to handle a large number of concurrent connections with high efficiency. Unlike traditional web servers that rely on threads to handle incoming requests, Node.js uses an event-driven, non-blocking I/O model. This allows it to handle multiple concurrent connections while using fewer system resources.

Another advantage of Node.js is its vast ecosystem of modules and packages available through the npm (Node Package Manager) repository. This makes it easy to find and integrate third-party libraries into your Node.js applications, saving development time and effort.

Getting started with Node.js

To get started with Node.js, you need to have it installed on your computer. You can download the latest version of Node.js from the official website and follow the installation instructions for your operating system.

Once Node.js is installed, you can open the command prompt or terminal and type node --version to verify that Node.js is successfully installed.

Now that you have Node.js installed, you’re ready to start writing your first Node.js application. In the next lesson, we will learn how to create a simple “Hello, World!” web server using Node.js.
