JAVA VS NODE.JS

JAVA VS NODE.JS

1) Languages aren't compiled or interpreted: implementations are. Java has had a decent optimizing compiler for a long time, but JVM 1.0 wasn't exactly a speed daemon. JavaScript was a dog for a long time, but modern engines like V8 compile it to native machine code.

2) Node.js isn't fast. It's concurrent. You can handle many thousands of simultaneous requests, as long as none of them are working particularly hard.

3) Exactly what collision course are we talking about? I can't imagine many situations I'd consider Node.js for that I ever would have though about Java for in the first place. If anything, I see Node.js as more of a competitor to Python for building scalable backend services.

4)I said that "Node.js is concurrent" because 

a) the summary claims it's fast, and 

b) Node.js fans who don't fully understand it seem to think it's magically fast. No, it's not particularly fast: it's just able to handle a lot of requests at once. Those are orthogonal.
