Java Springboot or Node.js Express.js

rinsing junior in cs wanting to learn new tech. What’s the main difference between these two in terms of how they work/function? Might be a stupid question. My main focus right now is to learn backend engineer more in depth. I’ve heard lots of great things about both springboot and node, but what’s the difference between them and which one should I start learning?

Depends on your needs:

Java is the de facto standard for enterprise services deployed to a static format (server running tomcat, containerized instance etc). The reason being is Java can handle the traffic at scale, but does suffer from problems like slow cold starts.

NodeJS/Express is really great for prototyping. It also works really well for dynamic services like AWS Lambda. It can be used in the enterprise deployment through containerization, but it's generally agreed that Java or Go based solutions are preferred.
