I am provided with the opportunity to learn one of these technologies during my training. I have prior experience with Spring and found it tough and still haven't figured out when to use what annotations among the thousands of annotations provided. On the other hand, I am very proficient in Java data structures and algorithms (custom comparators, etc.)
I have used Node.js and found it interesting, but I am wondering If I am taking the risk of choosing a framework that has a comparatively lesser scope in the future. One advantage I see with the node.js is the number of tutorials available and the ease with which I can code.
Please recommend which path to take. Is Spring learnable, or should I spend my energy on learning Node.js instead?
hi this depends where you want to advance . If you want to work for an big aged company with a lot of legacy go the spring way (banks, insurances netflix etc ) if you want to go the new agile fast cloud way learn node js it is much more suited for cloud and micro service even spring cloud can do that as well but it is much more heavier
I do not know Spring or your company/specialty. Of course it must be learnable and I won't tell you to give up on anything. Java is and will remain valuable.
Regardless, I don't think "lesser scope" is a valid strike against Node.js here. Node.js fulfills JavaScript's original vision of an everywhere language and can run anywhere that Java can. It serves webpages, communicates with hardware, powers command line tools, and builds desktop applications. A huge complexity-saver for teams running many environments (my biggest regret is that it cannot run a microcontroller).
Node.js' biggest practical weakness is that JavaScript is less structured than Java. Luckily, the large influx of Java developers has been helping with this: gaps like constants and private properties are gradually filling in, and TypeScript firms up the types to the point where JavaScript looks a lot like Java.
Probably more potential competition from the larger pool of JS developers, but the compensation is allegedly similar so I guess there is a similar supply/demand situation.
