web based business development and node js

I really shocked when i install node js and run few test scripts. it's tremendous and powerful and gives wings to do anything. we can build chat server in few minutes ... can build web server,TCP/IP service,Message Queues,DB connections etc. 


Main advantages are:

1. Web development in a dynamic language (JavaScript) on a VM that is incredibly fast (V8). It is much faster than Ruby, Python,PHP or Perl.
2. Ability to handle thousands of concurrent connections with minimal overhead on a single process.
3. JavaScript is perfect for event loops with first class function objects and closures. People already know how to use it this way having used it in the browser to respond to user initiated events.
4. A lot of people already know JavaScript, even people who do not claim to be programmers. It is arguably the most popular programming language.
5. Using JavaScript on a web server as well as the browser reduces the impedance mismatch between the two programming environments which can communicate data structures via JSON that work the same on both sides of the equation. Duplicate form validation code can be shared between server and client, etc.

 While i am elaborating things , will share few more things with screen shots. which might be intrested to you people to understand magic of NODE JS.
