If you are looking for Node.js development services, you first need to know why Node.js is better than Java. Here we have compared Node.js vs Java based on factors like advantages, disadvantages, scope, application and many more.

The technology is much advanced than our expectations. Both the technology, i.e., Node.js and Java, are in demand. These languages are two of the most used programming languages by developers around the world. As per Statista, around 35.35% of developers use Java, and 30.19% use Node.js, but this difference will dissolve very soon. As per the latest industry trends, Node.js will be on top of Java.

Both technologies have equal importance from the enterprise mobile &  web app development point of view, where Java works like a programming language and Node.js is an open-source backend JavaScript runtime environment.

So, instead of exploring too much deep information, let’s compare these two legendry technologies used by any software development company.

Here we will start with an overview of both. 

Overview of Node.js vs Java

There is a trending discussion in the IT world now about Node.js. It is such a promising JavaScript runtime environment. We will read the overview in this blog segment to build some basic understanding before landing on further discussion.



It was the year 2009 when Node.js was developed and launched by Ryan Dahl. No one thought that it would become a great sensation in the world of programming. It is a cross-platform & open-source JavaScript (JS) runtime environment that facilitates the developers to write programs for client-side and server-side using JavaScript.

It is not a programming language but an environment that works with JavaScript. The developers can execute their code on the server and helps them to write lightning-speed scripts. Indirectly it leads them to write, build or develop scalable network applications.

One of the best things is there is no issue of deadlocking as almost all functions of Node.js do not directly handle I/O. So it ensures the continuous running of the process instead of blocking. It is the prime reason that developers prefer Node.js for developing scalable systems. It is very useful in developing a single-page application, websites, and backend API services. It makes Node.js Development Company the best option to hire for web and mobile apps.

From the overview, 66.8% of developers rated Node.js as the most beloved tool, and 85% of Node.js developers use it for creating web apps as per the Stack overflow survey report.


One of the favorite choices of developers when it comes to object-oriented programming. Java works on the WORA concept that stands for write-once and runs anywhere. The code works on all platforms with ease, and there is no need for recompilation.

It is launched in 1991 and developed by Sun Microsystems (now merged in Oracle). Its prime quality is security, stability, and flexibility. It empowers the java development company to create applications for banking, ecommerce, fintech, transportation, and many other sectors. Still, most Android developers use Java for android app development.

It has four platforms such as JAVA SE (Standard Edition), JAVA EE (Enterprise Edition), JAVA ME (Micro Edition), and JAVA FX. In addition, Java language specialties make it the top five most used programming language.

#4. Multitasking

Due to the multithread nature, multitasking is possible; however, deadlock is also an issue.

#5. Platform Independent

The code written in Java can be run on any platform swiftly and smoothly. The only requirement is JVM must be installed on that particular device.

Cons of Node.js vs Java

Another side of the coin is that you need to know to analyze the things between Node.js vs Java.


#1. Slower Productivity

As developers need to write the code from scratch that leads to slower productivity as some beginners may find it difficult.

#2. Less Supportive for Heavy Computing

Node.js is fantastic for complex apps but less supportive for heavy computing and scientific calculations. It also does not support multithread programming.

#3. Complex Coding

The Node.js code remains a little bit complex to read and write.

#4. Lack of Quality

Some of the Node.js tools are less compatible with the high standards of coding.

#1. Memory Utilization

The Java framework utilizes more memory than the other object-oriented programming languages such as C++.

#2. Lags Backup facility

Java programming language only focuses on storage, not on the backup. It is a reason that developers tend towards dynamic programming frameworks such as Node.js.

#3. Not Perfect for Android API

Although Java is okay for initial Android development, its limitations create issues while developing android APIs.

#4. Not Suitable for Development from Scratch

Java is not suitable for development from scratch.
