From a security perspective, what does node have to offer? Exploits, that’s what. Node requires it’s own HTTP server which leaves you exposed to vulnerabilities from the World-Wide-Web.

What about performance? Node actually causes latency to exist and slow database updates (this has been proven by numerous SpiderMonkey benchmarks). This is due to the fact that Node is actually based on V8 of Chrome which means that it is 22 versions behind of the current version (30 or 31 beta).

If you really feel like jumping on this Node bandwagon to hell, please do yourself a favor: Don’t. Javascript is just fine for what you need. It has been around for over a decade and I’ve personally never had a problem with it. Why would you take a chance on some new unproven tech that is actually SLOWER (once again, proven by multiple graphs) than what existed previously?
