Selecting the right languages, tools and platforms have a huge impact on the software’s functioning – from the simplicity of its creation to the performance and efficiency it can provide. So, once you’ve decided to launch an app, you’ll probably want to consider building your stack around JavaScript – one of the most popular programming languages that are used for websites and non-browser environments as well.

And, for the backend development, programmers suggest using Node js – a cross-platform and open-source environment. In fact, this technology has become extremely popular over the last few years and, thanks to its characteristics, will continue to stand the competition in 2022 for many startups and enterprises.

What Is Node.js & How Does It Work?

Node.js is an open-source, cross-platform runtime environment and library for Chrome’s Javascript, that is usually applied for developing and running scalable web applications outside the client’s browser. Node.js environment is built on top of Google Chrome’s JavaScript Engine V8, which uses an event-driven, non-blocking I/O model – lightweight, more productive, and an ideal option for data-intensive real-time apps running across shared devices.

In other words, that’s not either a framework, programming language, or library, which is used for the traditional application software, Node.js is an environment for them.

Today, this environment is popular not only because of the right time and right place; it happened to be built in 2009 by Ryan Dahl. Instead, designed with real-time push-based architectures in mind, it features a large scope of innovative approaches for JavaScript server-side development.
