It opens up new perspectives, still having its “browser” nature. The developers use both the languages to develop applications depending on the preference and the need of application. Let’s dive into Java vs Node.JS comparison to understand the two technologies better.
Ubiquity in Node.JS
Java has Better IDEs
Java developers have Eclipse, NetBeans, or IntelliJ, three top-notch tools that integrate well with debuggers, decompilers, and servers. Each has years of development, dedicated users, and solid ecosystems filled with plug-ins.
Meanwhile, most Node.js developers type words into the command line and code into their favorite text editor. Some use Eclipse or Visual Studio, both of which support Node.js. Of course, the surge of interest in Node.js means new tools are arriving, some of which, like IBM’s Node-RED offer intriguing approaches, but they’re still a long way from being as complete as Eclipse. WebStorm, for instance, is a solid commercial tool from JetBrains, linking in many command-line build tools.
Of course, if you’re looking for an IDE that edits and juggles tools, the new tools that support Node.js are good enough. But if you ask your IDE to let you edit while you operate on the running source code like a heart surgeon slice open a chest, well, Java tools are much more powerful. It’s all there, and it’s all local.
With Node.JS Build process simplified by using the same Language
Complicated build tools like Ant and Maven have revolutionized Java programming. But there’s only one issue. You write the specification in XML, a data format that wasn’t designed to support programming logic. Sure, it’s relatively easy to express branching with nested tags, but there’s still something annoying about switching gears from Java to XML merely to build something.
Java for Remote Debugging
Java boasts incredible tools for monitoring clusters of machines. There are deep hooks into the JVM and elaborate profiling tools to help identify bottlenecks and failures. The Java enterprise stack runs some of the most sophisticated servers on the planet, and the companies that use those servers have demanded the very best in telemetry. All of these monitoring and debugging tools are quite mature and ready for you to deploy.
Java for Libraries
Node.JS for JSON
When databases spit out the answers, Java goes to elaborate lengths to turn the results into Java objects. Developers will argue for hours about POJO mappings, Hibernate, and other tools. Configuring them can take hours or even days. Eventually, the Java code gets Java objects after all of the conversions.
Java for Solid Engineering
It’s a bit hard to quantify, but many of the complex packages for serious scientific work are written in Java because Java has strong mathematical foundations. Sun spent a long time sweating the details of the utility classes and it shows. There are BigIntegers, elaborate IO routines, and complex Date code with implementations of both Gregorian and Julian calendars.
Java for Threads
Fast code is great, but it’s usually more important that it be correct. Here is where Java’s extra features make sense.
Java’s Web servers are multi-threaded. Creating multiple threads may take time and memory, but it pays off. If one thread deadlocks, the others continue. If one thread requires longer computation, the other threads aren’t starved for attention (usually).
However, even if one Node.js request runs too slowly, everything slows down. There’s only one thread in Node.js, and it will get to your event when it’s good and ready. It may look super fast, but underneath it uses the same architecture as a one-window post office in the week before Christmas.
There have been decades of work devoted to building smart operating systems that can juggle many different processes at the same time. Why go back in time to the ’60s when computers could handle only one thread?
Node.JS for Momentum
Yes, all of our grandparents’ lessons about thrift are true. Waste not; want not. It can be painful to watch Silicon Valley’s foolish devotion to the “new” and “disruptive,” but sometimes cleaning out the craft makes the most sense. Yes, Java can keep up, but there’s old code everywhere. Sure, Java has new IO routines, but it also has old IO routines. Plenty of applet and until classes can get in the way.

Java is faster than Node.js. Java relies on multi-thread architecture. Creating multiple threads may take time and memory, but it pays off. If one thread deadlocks, the others continue. Whereas, there is only one thread in Node.js. If one request runs too slowly, everything slows down.
