Feedback

    * Hi all, I'm working on a new project, and this is the first time I've ever looked for a JavaScript obfuscator. I was trying to use the Javascript Obfuscator 4.0 trial version on my javascript file and as it appears to find and java script obfuscate all my variable and function names. Also it works very quickly even with big files.

    * My company want to buy a tool to obfuscate our javascript source, and I download your trial version of JavaScript Obfuscator 4.0 to have a try. Command line interface is very usefull for us to automate the javascript optimization.

    * I have tried the evaluation version of your JavaScript obfuscator, everything went fine, it looks really nice. I really like the ability to add a comment header to each compress javascript file. I use this option to include a copyright notice in my commercial script.jscrunch microsoft minification
