Why should you use Node.js?

The world of web page creation has changed a lot in the last decade. Along with changes in development, there have also been changes related to user experience. This is all because applications have become more dynamic, fast, and interactive. To do this, many features that were previously developed with server-side code known as “backend” have been moved to client-side code with Javascript called “frontend”

Node.js is characterized as a JavaScript runtime. With it, the user can create applications without depending on the browser. With high scalability, good flexibility, architecture, and low cost, it becomes the best option for programming. As node.js grows in popularity, node.js development services become more relevant.

If you’d like to learn more about what Node.js is for, its characteristics, how it can be used, and the benefits it brings to your development, keep reading this article.

Why should you use Node.js?

Server Side vs Client Side: What’s the Difference?

Since Node is defined as a server-side interpreter, we first need to talk about it and also explain the differences from the client-side one. Also known as back-end and front-end, respectively.

Like server-side languages or seja, on the server-side, these are the languages ​​in which the written code is understood by the server. Therefore, it is processed and the response is passed to the browser.

Because client languages ​​are barely understood by the browser, they are handled by the browser, not the server. Because there is no internal processing, the user gets older responses and uses less bandwidth.

Features of Node.js

Thanks to the many improvements made to the JavaScript language and its execution engines, his application has more purposes than just manipulating HTML pages.

One big difference is Node’s single-threaded execution, where only one thread executes application code. Thus, fewer computing resources are required, since there is no need to create a new thread for each request received.

On a traditional server, since resources are limited, new claims will be processed as soon as resources are freed, otherwise, it may delay the user.

Or Node.js only uses one thread called the Event Loop, which creates new events for every request it receives. Login and logout actions, for example, we don’t have to wait for an operation to complete before starting another one.

Benefits described by Node.js

Let’s move on to the main benefits that users get when using Node.js.


Because JavaScript is the most commonly used language in web development, Node.js offers several features, including code reuse, that allows teams to make better use of available resources.


Node.js is a very versatile framework that can be used in many scenarios. Its package manager (Node Package Manager) is classified as the largest software repository available since the most famous package is a web development framework called Express.js.


As we have already mentioned, due to the single-threaded format, the computing resources are much less required when using the language node. In terms of the speed of system availability for use (deployment) and replication of machines, it can grow significantly.

Now you know everything about Node.js. Thanks to all these characteristics and advantages, its popularity is growing by leaps and bounds.
