NodeJS and Java are widely accepted backend development technologies.
Since both are top contenders for each other, it is difficult to choose among them. Oftentimes, it is confusing for experienced developers to choose among them. You need to take this decision looking at all the sides of the coin because this decision can make or break your project.
With the intent to help you make an informed decision, we are presenting a detailed comparison between NodeJS vs Java.
What is NodeJS
Node.js is a dynamic, open-source, cross-platform JavaScript runtime environment for building fast, scalable applications. Millions of developers worldwide use NodeJS to build the next generation of web applications.
It allows you to run any server-side as well as client-side code and has a flexible runtime ecosystem for building very fast, single-page web applications. It is an alternative to Python or Ruby because it has a more straightforward syntax than these languages.
Node also allows the client-side of an application to be part of the same application as it runs on a web browser. In other words, Node enables you to write scalable, reliable JavaScript applications hosted on your own server or any other development platform using the same backend code.
One of the best features of NodeJS is that there is no deadlocking since all the functions do not handle I/O directly ensuring a continuous process, which is why developers prefer it.
Advantages of NodeJS
Reuse of code: NodeJS developers can reuse the code whether it is for server-side or client-side.
Quick processing: Being an event-based model, it can handle concurrent requests.
Rich ecosystem: NodeJS has millions of libraries and free tools available to fast-track the app development process.
Disadvantages of NodeJS
Inferior quality: Some of the tools do not comply with quality standards.
Difficult to maintain code: NodeJS being an asynchronous technology, it is pretty tough to maintain the code.
Cannot handle heavy computation: node JS is less efficient; it cannot handle heavy calculations.
Use cases of NodeJS
NodeJS is a tool for building web applications. It has a modular architecture used to create server-side applications. It has a massive community behind employing NodeJS in building robust, scalable applications. Following are the use cases of NodeJS
- Queued Inputs
- Fine data streaming applications
- Fast and scalable network applications
- IoT-based applications
- Real-time website with push capability
- Scripting and automation
- Enterprise chat applications
- Complex single-page apps
- Client-side app for Proxy
- API development
What is Java
Java is a programming language and platform. It is designed for building high-performance, scalable, and secure applications. Java runs in many different operating systems and on many other hardware platforms. It is procedural, object-oriented, and a very flexible coding language. It has a simple syntax that allows you to write code with very little explanation to do one thing very well. Java’s learning curve is short because it has been
designed to learn and use it in just a few hours of training.
Over the years, there have been several revisions of Java, including the Java SE (Standard Edition) and JAVA EE (Enterprise Edition), JAVA ME (Micro Edition), and JAVA FX.
Java has an extensive codebase hence, so many other programming languages written in Java is used alongside it.
Java works on “WORA” or “Write Once, Run Anywhere.” This term refers to a concept in which you can create and run your website from an application on the web. The main idea is that you do not need to rewrite the code for different devices.
Advantages of Java
Security: Java is considered a highly secured programming language among its peers.
Multitasking: Being multithreaded in nature can handle multiple tasks simultaneously.
Independent technology: Java does not require any platform or a system to run its application.
Disadvantages of Java
Sluggish performance: it consumes a lot of memory; thus, it is slower than sea and C++
Paid licence requirement: From 2019, a pet license would be required to use the standard edition of Java.
Less readability of code: The Java code is less readable than other backend and technology.
Use cases of Java
Java developers write portable, concurrent, and distributed programs, and these applications/programs get installed and run on any device. It is a widely-used programming language. Following are the use cases:
- Mobile applications
- Cloud applications
- AI apps
- Big data applications
- Embedded systems
- Desktop GUI application
Comparing NodeJS vs. Java
Node.js, a popular JavaScript-based open-source platform enabling developers to build and run large-scale, scalable applications. It is an asynchronous event-driven server framework that is reliable and fast and develops applications with minimal effort.
On the other end,
JavaScript is a programming language that runs on the server-side of a web application. Such as websites and mobile apps, or for building server-side applications such as databases or APIs.
Let’s compare these coding technologies in various aspects to know which is the best.
Performance – NodeJS vs. Java
The JavaScript event-driven approach of Node.js has a significant impact on its performance and scalability, and it is fast enough to handle multiple tasks. Moreover, NodeJS employs Chrome’s V8 Javascript engine, which adds a feather to Node’s performance.
Java programs are written in byte codes; thus, they offer faster performance than other coding languages. The Just-in-time (JIT) compiler enables the high-performance potential of the application.
Scalability – NodeJS vs Java
Node.js can be used to build fast and highly scalable applications. The event-oriented models and non-blocking input and output systems facilitate the processing of concurrent requests. Besides, the event-loop mechanism enables the server to cater to multiple requests at once. Hence the NodeJS applications are easy to scale.
Since Java offers horizontal scaling, vertical scaling, and a single point of failure, scaling an application is easy. But it is possible when you implement the best Java app development practices.
Application Architecture – NodeJS vs Java
Node.js uses an event-driven system for managing concurrent requests of users at a high-performance rate. In addition, the asynchronous architecture allows the use of an MVP/MVC architecture pattern that simplifies isolation and onboarding issues.
Java offers model-view-controller architecture to develop applications. It also provides hassle-free maintenance of code with a simplified testing process.
