serverside-javascript

I just started experimenting with Aptana Jaxer server side javascript engine for my next project. And i have few quesions about that By using server side JS, can we implement the whole web application without using any server side languages (like C#,java etc). Or server side JS sits in between the web server and other langauge stack. Is it really a better approach ?? what are the advandages and disadvandages? how this works well in terms of performance? is there any real time implementation (public websites) only using server side JS(no other languages)? what are the alternatives available

I've started tinkering with Node.js HTTP server and really like to write server side Javascript but something is keeping me from starting to use Node.js for my web application. I understand the whole async I/O concept but I'm somewhat concerned about the edge cases where procedural code is very CPU intensive such as image manipulation or sorting large data sets. As I understand it, the server will be very fast for simple web page requests such as viewing a listing of users or viewing a blog post. However, if I want to write very CPU intensive code (in the admin back end for example) that

I have a pet project that is an online game, the entire game engine is written in C# and I would like to know if there is anyway I can call the functions of this existing assembly (.dll) from a solution built using Node.JS, Socket.IO, Express etc? The game engine itself is pretty complete; tested and robust. I am hoping there is some neat way of exposing its functionality without too much overhead. UPDATE : To answer my own question a little.. I have ended building my own web socket server (based on the most current web socket protocol document). It is written in C# and compiled using Mono so

Possible Duplicate: How to decide when to use Node.js? Sorry if I'm a bit ambiguous, but I'm trying to understand the real advantages of using Node.js instead of other server-side language. I'm a JavaScript enthusiast, so I'm probably going to play with Node.js, but I want to know if I should use it in my projects. Raynos It's evented asynchronous non-blocking I/O build ontop of V8 . So we have all the performance gain of V8 which is the Google JavaScript interpreter. Since the JavaScript performance race hasn't ended yet, you can expect Google to constantly update performance on V8 (for free)
