How can I convert minimized java script to early Edition?
Is any software or website for this work?
Thank u for hints.
No, there is no software to unminify javascript you can minify it but reversing is not possible, if you are creating your own javascript code then you must keep both javascript versions minified and unminified for future reference.
And if you are using a javascript library or framework then both versions (minified and unminified) will be available on that site.
JavaScript cannot be "unminified". The purpose of minification is to represent the original javascript in the least number of characters. However it is a one way transformation since there are no clues in the minified version that can lead you back to the original content.
Ex: the variable myLongVariableName can be minified to just a since the JavaScriupt interpreter doesn't care about human readable variable names. However, after it's been mapped to a there is no way to map it back to myLongVariableName

I have gone through many articles of SO and Googled a lot but could not find some good premade libraries to prevent XSS (Cross Side Scripting) with Javascript for Node.js and PHP for Apache. I have found a lot of codes to prevent but isn't there some good libraries already available just include and use it?
php-antixss
htmLawed
HTML Purifier
xss_clean.php filter
XSS Protect
HTML XSS Filter
You can check it out Mod Security (kinda Module)
can be libraries, first go through their docs. But I would suggest you to use your own code for better prevention against such attacks.
It is essentially possible to automatically prevent XSS attacks, since one little line in the code written by the end-user (the developer using such a theoretical library) can open up an attack.
It isn't possible write such a library, you just have to be careful.
If it is a high priority project, the only thing you can really do is be careful and get a third-party security audit from a trusted source (though those usually cost several thousand and the low-end).

Is there a library which makes all browser's JS interfaces comply to W3C standards?
For example, one that will add addEventListener to IE8, based on attachEvent.
EDIT 2022. core-js was created a year after this question. I guess it wasn't that much off-topic, huh?
Every modern javascript framework offers you methods to even out these inconsistencies in the browsers js implementation (like jQuery's on handles addEventListener/attachEvent). Most of these frameworks however don't use the approach to alter the host objects (which is considered problematic) but their methods internally map to the according functions available in the specific browser.
I suggest you try one of those many popular frameworks (like e.g. jQuery, MooTools or Dojo to name only a few of the more popular ones).
I suggest to NOT use a framework which alters the host objects directly (as some of them tried in the earlier days and later discovered that this causes many problems).

iam looking for some tools or ways to detect memory leaks, slow methods in my javascript app.
You need to use the profiler; I recommend Chrome's. In the profiler the steps are
Go to the profile part of the developer tools
Get to the part where the slow js is
Start recording
Start the suspect code
Stop recording
After that, the profiler will tell you everything you want to know about how many objects there are, how much time is spent in each method, etc...
The procedure should be similar with Firebug on Firefox.
Good question. Profilers/browser plugins are handy, but very well may yield results unique to the browser being tested on. There are a number of techniques available from testing via multiple browser's plugins/profilers to inline debugging performance statements.
Two good articles with, robust examples and recommendations:
How do you performance test JavaScript code?
Memory leak patterns in JavaScript

I see that javascript is becoming more and more practical as a server side language with the advent of node.js and v8. As far as frameworks go, most of what I've seen are minimalistic frameworks. Even express.js, one of the more promising ones, is a little bare.
Are there any full stack server-side frameworks out there for JS yet?
There's RingoJS, the current form of the (surprisingly old) Helma framework. It's a Rhino-based implementation, so you can get whatever you want from the JVM (sort-of a "good news/bad news" joke I guess).
Check out towerjs and railwayjs.
There is a very powerful webapp stack called ringojs. It is actually a Rhino prompt that you can use to run javascript modules. It is based on Jetty and features a well designed set of modules and a powerful but simple template engine (including inheritence and macros). You can reuse the galaxy of Java libraries out there throught simple Javascript-Java interop. Coming from J2EE development I threw out a lot of ceremony code and configuration - it is very productive, especially tweaking your running webapp throught the prompt

I'm working on a piece of logic that I would like to express on the server as well as in the browser. Something like validating a form where there must be certain logical relationships between the elements based on what has already been entered.
So... If I can write the logic once and somehow end up with both Ruby and with Javascript, I can write the logic just once and not have to worry about making sure that two pieces of code written in different languages have the same functional behaviour.
I don't need to reproduce everything in Ruby, obviously, and one simplification might be to port a single general-purpose library like Functional Javascript to Ruby.
Does anyone have experience with RubyJS? Can anyone point me to an existing project using RubyJS?
Thanks in advance...
As far as I can tell, Opal is the best Ruby to JS converter/compiler out there right now. Here you can see it in action.
It isn't perfect, but it works most of the time and unlike older projects such as RubyJS, Opal is still being actively developed.
I know about http://hotruby.yukoba.jp/ but have never used it
maybe this helps:
http://opalrb.org/
haven't tried it though
I recently heard about a project named "Johnson" which embeds the Spidermonkey JavaScript interpreter inside Ruby. http://github.com/jbarnette/johnson
You could then eval some javascript inside ruby.
