I stopped reading at the part with the "Type information". Or better i should have stopped... Another post about(and the from paypal too) about my language X vs language Y...

It's the same flameware like Facebook started with its we can't get HTML5 as fast as native... then some people who know what they where doing did it...

No don't use java No don't use javascript

For god sake learn one language or two and learn it very well! i mean very well! and you will write good code and performant code...

EDIT: Why do i get down voted? Jesus HN gets worse and worse...

You're getting downvoted because this isn't a "language X vs language Y" article at all. Its point is that the language choice doesn't matter when you're building on top of crap, and jumping from one language to another probably won't solve platform problems. It's an article about the politics of being a software developer in enterprise where management is entrenched in legacy codebases, not about language features.

What? the first part is exactly that... for example: "So which is the faster virtual machine, V8 or JVM? My belief is that when you are coding in the most basic building blocks of either virtual machine (i.e JavaScript vs JVM Byte Code) that the JVM will win out every time. If you start to compare higher up, you may end up comparing apples with oranges and see false comparisons. For example, if we consider this comparison of V8 vs JVM performance at mathematical calculations. This blog post tells us that if we relax our specifications we can calculate things faster. Here is the specification that V8 must use for Math.pow and here is the specification that the JVM must use for Math.pow notice that the JavaScript specification allows for an “implementation-dependent approximation” (of unspecified accuracy) while the JVM version has the addition that"

and at the second part too: "... a limit of Node.js itself when used with the backing APIs that they have to call through to."

It's just hidden better... to me it reads like a java fan boy is crying why a company switched to language X from his language Y...

Your analysis is too shallow. The only reason he attempts to compare node.js to Java at all is to reach his point: that the decision was probably more about company politics than tech benefits. The team used a different language not because it's better or worse, but because it'd allow them to avoid building on top of the existing framework -- a chance to get rid of technical debt and start a fresh code base, even if just a seed.
