Javascript is a critical component of today’s Web pages. It was important back in 2005 but now it’s everywhere. Yesterday i noticed that 90% of the top 10 000 websites use Javascript: http://trends.builtwith.com/docinfo/Javascript
This is huge!

For me the most important developer in Javascript obfuscation / optimization / compression are currently:

Google Closure :

Because of the high performance minification and optimization.

JScrambler:

Because they try to do it all: compression and protection and are very effective at both.

And for me one the most important features is that both are actively developing their platforms.

did you try javascript obfuscator from http://www.javascript-source.com/ ? they promise the best compression ratio for js code. is it true? it's commercial :(, but a trial is full-functional.

That obfuscator is not available anymore. In need of one, I wrote it and release it as open source. You can check it out at http://digua.sourceforge.net. It also works for HTML and CSS.

JavaScript Online Obfuscator is a integrated solution for confusing javascript source code. It confuses local variables, arguments of functions and methodes, but doesn’t confuse javascript core and client’s classes, functions, methods or properties. It is compatible with Core JavaScript, Client-Side JavaScript, W3C DOM, XML, XML Schemas(SOM), XSLT, AJAX(XMLHTTP) and other third party object. You may decide if confusing your owner’s global variables, classes, functions, methods and properties in source code, according to obfuscating rules. It is easy to use, doesn’t need complex operating and large configuration file.

I’ve tried many JS obfuscators and optimizers and most of them are buggy :( I’ve used Jasob and w3compiler for some time but eventually found TrickyScripter (http://trickyscripter.com) and I like it more than anything else now. The bad news is that it is a Dreamweaver plugin :( Hope they will release an executable for Windows soon.

He who needs to use an obfuscator for JavaScript (!) shouldn’t be “programming” in the first place. But that’s just my opinion.

There is also this http://www.saltstorm.net/depo/esc/

“ESC is an ECMAScript pre-processor written in JScript, enabling an unlimited
number of external scripts to be compressed into supertight…”

can do Obfuscation as well.

Dojo is using a custom Rhino build to accomplish much the same thing:

http://dojotoolkit.org/~alex/js_with_compress.jar

Since it’s built on the Rhino parser, it’s pretty solid and not prone to the kinds of bugs that most regex-based processors fall prey to (including the earlier ones I’ve written).
