I enjoy API development and have a slight Java preference because I've done more in it, but preferring API development vs frontend isn't a matter of the language, but the process of building APIs. This just illustrates that you should find out which "side" you enjoy more (frontend vs APIs, to put it broadly) and focus less on the programming language specifically.

r/node on Reddit: Node.js or Java for Backend? Seeking Advice for Fullstack Transition!
August 30, 2024 -

Hey everyone,

I could really use some advice. I've been working as a frontend developer for almost 2 years now, mainly with React, React Native, and Redux. I want to level up and become a fullstack developer, so I'm diving into backend development.

Initially, I thought of learning Node.js since it uses JavaScript, which I’m already comfortable with. But one of my seniors suggested I should consider Java because it’s more powerful and could lead to better job opportunities.

Here's where I’m stuck:

  1. Familiarity: I know JavaScript pretty well, so picking up Node.js might be easier and faster for me.

  2. Learning Curve: I’m a bit of a slow learner, and Java would be completely new territory, meaning I’d have to start from scratch.

  3. Career Prospects: While Node.js seems like the easier path, Java supposedly offers more robust capabilities and better job prospects.

For those of you who have experience with both or have made the transition from frontend to fullstack, what would you advise? Should I go with Node.js for a smoother learning experience, or should I tackle Java for potentially better career opportunities?

Thanks a ton for your help!

It’s more about the concepts. Are you familiar with (or do you want to learn) how Spring works? Learning Java is not hard. It’s dot notation, like JS, but it’s compiled, there’s strict typing, and much more heavily focused around OOP. How well do you know OOP? How familiar are you with abstraction? If I were you, I’d stick with something like Nest.JS and focus on learning proper typescript, and then move into Java. If you’re not good with key programming principles, then Java will be brutally hard. If you’re familiar with stuff like OOP, inheritance, polymorphism, abstraction, singletons, factory methods, et al., then Java might be a good challenge! Also, consider time. Do you have the time to learn Java? Or would that time be better spent on learning a solid TS framework, like Nest.JS? I’d say learn TypeScript properly, and focus on Nest.JS (or some other framework), and then learn Java and port your api to it when you have the time! Good luck either way, bud! [EDIT] career wise, don’t worry. PLENTY of node jobs out there! But be sure to stand out by knowing programming principles, not just node. I’m a hiring manager. I literally don’t give a fuck if you know how to make an express app. I care that you know how to stream a file, what buffers are, how to find performance issues, database normalization, et al. If you know that, learning a new language becomes a lot easier!

You'll pick the concepts faster in the language you alresdy know. Afterwards, you can choose to transition to Java. More Java jobs but at the end of the day, if you know and understand the concepts very well, it doesn't matter what you choose

r/cscareerquestions on Reddit: Career in NodeJS vs career in Java ???
March 13, 2019 -

Hi everyone,

I've been using React / Redux on the front-end and Java / Spring Boot for back-end at work for about a year now. I really enjoy working with JavaScript as it has an amazing community, great libraries and I can write code in a functional way, which I much preferover oop.

I'm at a point now where I'm not sure where to go with my career. I'm not sure wether I should go down the NodeJS route and focus on JS or if I should go down the Java route as it is more in demand.

Java can be quite verbose and sometimes it's hard to find documentation that's easy to understand, and I'm not as experienced with it as I'm with JS. But it seems like the more complex and reliable pieces of software are built in Java, so it makes it quite a good choice as well.

I'm curious if any of you have been in a position like this before and what decision you made. Thanks!

r/cscareerquestions on Reddit: Which offer to pick, Senior Node.js vs Java?
February 15, 2025 -

Hey everyone, I could really use some advice here.

I have about 4 years of experience as a backend working with Node.js. Recently, I received two offers:

  1. Senior Backend Developer (Node.js) – This role would bump my salary and give me a senior title, which would look great on my CV and contribute to my work experience.

  2. Software Engineer (Java) – This wouldn’t increase my salary but would allow me to pivot into Java, a language I currently have no professional experience with.

I already have a pretty good salary for my country (Sweden), so the salary bump isn’t a huge factor. What I’m more concerned about is future career growth. I sometimes worry about the long-term prospects of Node.js and don't want to get stuck in a pigeonhole, and I wonder if pivoting into Java might provide more stability and open more doors in the future.

To be honest, I don’t mind working in either language. I just can’t decide which path would be better for my career in the long run.

What would you do in my situation? Anyone with similar experience? Would you prioritize the senior title in your current stack or branch out into Java for more opportunities ahead?

Any answers greatly appreciated!

Hello everyone!

What Are The advantage and disadvantages of using Java(springboot) instead of NodeJS as the back end of my web application.

Thanks in advance.

Few off the top of my head. NodeJS should only be picked if your load is almost entirely IO bound. You will see very few of the benefits otherwise. NodeJs codebases tend to scale smoothly until under full load while Java codebases front load a bit more. When under a full load it will depend on what sort of load to determine which one is better/faster. In general nodejs codebases perform better in horizontal scaling situations when you are running many small boxes while Spring boot/Java can better take advantage of vertical scalability. If you have one or two large servers running your application Java may outperform nodejs as it can take advantage of multiple cores when under load. Java is compiled and statically typed which eliminates several categories of bugs and you never have to worry about invalid code. NodeJS codebases require more written tests for the same guarantees and the inclusion of typescript. At the same time if your application does little with the data passing through its system it can feel like types are a burden instead of a boon. Java's tooling and deployment is a bit more complicated than NodeJs. Its changed a bunch over the years and it can be daunting to the inexperienced. Spring boot makes this easy if you follow their doc closely and don't try to figure it out on your own. Spring boot is a collection of libraries primarily centered around spring framework and bring in concepts you may not be familiar with. It would be more accurate to compare it to something like NestJS than NodeJS. You can pick a simpler Java framework to get started as there are many that can compare similarly to something like express in NodeJS. In my opinion, Java's standard API is easier to work with than NodeJS for a number of tasks. You may not encounter this in a simple application though. Spring boot codebases have certain common conventions on organizing code. This is useful to the experienced but can be overwhelming to new developers. tldr; If you are building a small web application that primarily talks to remote services like a DB use nodejs and you will get up and running faster. For larger apps or where performance is critical it would highly depend on what your application is doing for the choice to matter.

If you're building a prototype or toy, node is quick to get started with. If you will be running your application for a while and need to actually support it, Java. Source: 15 years or building large scale Java web services and 8 years with nodejs web services.
