In the tech industry, learning how to use tools and programs based on Java or JavaScript is essential. The use of these in-app development has become a significant part of the industry as well. Whether it involves front- or back-end elements, having experience in any aspect of app development remains in demand.

One such tool in the development process is NodeJS.

What Does NodeJS Do?

This cross-platform back-end tool, which is also open-sourced, runs code beyond web browsers. It’s known as a ‘runtime environment’. NodeJS allows for server-side scripting too, or the running of scripts before they are sent to a web browser. It encompasses one programming language that can be used throughout development.

Benefits of NodeJS

  • Singular Codebase

Since it utilizes one programming language, NodeJS can send data back and forth. This strengthens the code because it is used consistently, and decreases the time and code it takes to build the app.

  • Real-Time Integration

NodeJS functions very well with app features like live tracking, social media, and even gaming. It also has fast synchronization.

  • Low Learning Curve

Due to its reliance on JavaScript’s language, which is extremely popular among developers, the difficulty of learning NodeJS is lower.

  • Large, Active Community

NodeJS is used by Microsoft, among many other popular corporations, whose communities are dedicated and large. This extends to NodeJS as a result and helps developers improve it.

Where to Learn NodeJS

Being a popular development tool, there are many places where developers can learn how to use NodeJS. They range from articles to online courses and more. Some helpful courses are:

  • NodeJS – The Complete Guide (MVC, REST APIs, GraphQL, Deno) by Maximilian Schwarzmuller

This course covers elements of NodeJS such as concepts and understanding, building an app, and other tools that are similar.

  • Learn and Understand NodeJS by Anthony Alicea

Like the previous course, the basic functions and process of using NodeJS will be addressed. Additionally, how developers can use asynchronous code in Node is also included.

  • The Complete Node.js Developer Course (3rd Edition) by Andrew Mead and Rob Percival

On top of teaching developers NodeJS, the course looks at Mongoose, MongoDB, and ExpressJS. This class seeks to teach developers how to apply what they learn to the real world.

  • Node JS: Advanced Concepts by Stephen Grider

Its name suggests what the class is about—learning the more complex features and functions of NodeJS. This is recommended for developers who already know how to use NodeJS on a basic level.


Any tool of development that utilizes Java or JavaScript is almost always worth learning. The programming language itself is so widely used that skills with any tool implementing it should have some function. With NodeJS, it’s lightweight, server-side, and can be run with real-time features. Primarily single-threaded, NodeJS is best used for servers that are event-driven. It’s a back-end development tool that continues to grow in popularity and evolves as a beneficial part of the app development process.
