Recenty, I found one name of Node.js and I review and google it
and found some video and article about Node.js such as


http://dojotoolkit.org/documentation/tutorials/1.8/node/
http://blog.modulus.io/absolute-beginners-guide-to-nodejs
stackoverflow.com/questions/2353818/how-do-i-get-started-with-node-js
http://www.youtube.com/watch?v=jo_B4LTHi3I

And just conclude something from my understanding  that is

1-Node.js is server-side javascript platform
2-Create Http request on server--side by client  without apache on server  , Is it Right?

That is what I know, but all related article or video doesn't mention
what is advantage of using Node.js

So I guess that is
Normally on  browser webpage those Javascript code is at client-side so
user can run the code on its computer browser and can be viewed those code by
browser view source option.
And If we are using Node.js , we can put those javascript code into server side
and browser user can run it but from server and users can't veiw ths code.
I think that is good thing if so since we can write some javascript code saved
into server and also let user run it at server side so that



If not, I don't see anything from Node.js to improve my application and website security

If you know the Node.js behind, please let me know what is advantage and application
we can feel using Node.js, for similar example, what is advantage of using
facebook that is you can share or broadcast your information with others.

And I think Node.js should focus on telling people what advantage of using it first
before just all the time mention the code syntax  


Please advise

if you've the latestS Xeon on the server and your user run on a Pentium 1 I don't think... but it's not the question, it's not because you've javascript running on the server that you need to remove or don't user it on the client side;

using javascript on the server may help you remove some boring part on the client side for example when you need to query external ressource and process, you can save time and client-server requests

yes, of course they CAN'T


java, php, .net can't easily play with DOM
java, php, .net can't easily read, delete, add data from a JSON structure to a database
java, php, .net don't easily allow you to create a web service

what I like :
- javascript everywhere, when I send data, I don't need to fight, I simply use the data as they come no need to unserialize, serialize. Additionaly, using MongoDB simplify the storing of data, MongoDB is a "JSON database", to store I use a very simple javascript method
- javascript is good to play with DOM
- You should be able to use any Javascript plugin, for example you can use jQuery (not yet directly on windows), YUI, that mean you can build page on the server side using a javascript framework!

1-Node.js is server-side javascript platform
yes
2-Create Http request on server--side by client  without apache on server  , Is it Right?
yes

the question is how and why do you choose PHP instead Java or ASP.NET?
