Nodejs vs Java An Epic Battle

March 15, 2019

Technology leanings keep improving, and we should be ready to adapt to those changes as and when required. Java and Nodejs both are equally important in web development. Nodejs recently has gained its development practice compared to Java. This is to be noted that Java has existed for ages while Node.js has acquired popularity in recent days. Let us compare Node.js and Java to understand which is better.



Single-threaded Multi-threaded
Asynchronous I/O. Synchronous I/O.
More rapid due to its non-blocking nature Slower than Nodejs


Node.js is developed in 2009. This has proved its part in the Nodejs vs. java an epic battle through its speed and high performance. Node.js is neither a framework nor a programming language but an open-source, multi-platform JavaScript runtime environment that implements JS code externally. Moreover, developers also use NodeJS to build APIs. It is prevalently turning out to be the favored tool for software developers to create web applications. This serves as the bridge between the client and server-side programming. One can achieve ease of performance targets without making any significant alterations to the core application. If you have to work on small projects, Node.js is exceptionally easy to handle. In addition, it is easy to code with the required JSON support.

Node.js is a single-threaded runtime environment creating an advantage over java. This single thread handles all the incoming requests.  Node.js allows stress-free programming due to this property. Node.js focuses on performance and covering well for low-performance CPU, high I/O type of processes. This has also demonstrated its capability to perform better over cloud backgrounds and client virtual machines. This happens through devoted software. It is the most favored one among developers because of the code re-usage feature. Though it has restricted access to the server assets, its functionalities work fine making use of thread allocation.

Pros of NodeJS:

  •           A simple learning curve is enough for the beginners
  •           Developers can quickly build the software owing to the availability of library resources
  •           Code reusability feature
  •           Client and server-side programming

Cons of NodeJS:

  •           Lack of IDE environments
  •           Single-thread for processing all the incoming requests
  •           Does not offer scalability
  •           The relational database is a pain point
  •           The ecosystem is yet to mature when compared to Java

Java boasts a rock-solid foundation and the world’s most important environment of libraries and resources. Some of the stable development processes across the globe are dependent on Java developers. They prefer using Java for their outstanding projects. Its features like steadiness, expertise over multi-threading, specific functionalities facilitate them to do so. Additionally, there are in-built debugging abilities integrated with debuggers, decompilers, and servers.  The power of JVM makes it a super easy language to use. Java developers can use Eclipse or NetBeans or IntelliJ, three top-notch tools. These are finely integrated with debuggers, decompilers, and other resources. Java won the battle when we considered some of its pros as follows.

Pros of Java:

  •           Thanks to 20 years of efforts and its solid base.
  •           A diverse environment of libraries which the programmers can utilize to improve the quality of development
  •           Outstanding constancy offered by JVM
  •           Superior quality IDEs

Cons of Java:

  •           Development process consumes time
  •           Deadlocks are a significant disadvantage. Your project is at high risk.
  •           Configuring the tools and resources may take a long time.
  •           Code migration is tough.

This is an ultimate battle for developers to pick the appropriate framework. The fight can go on with supporters of both the frameworks making persuasive arguments about it. But the final verdict depends on the type of your project. No structure can offer everything that you may need. Similarly, no single language can answer all of your questions. Therefore, look at the advantages and disadvantages of both and pick the one that best suits your needs.
