I am looking for way (preferably and online site) to a reverse Uglify of some javascript. The Website: http://jsbeautifier.org/ is great for minifed code, but it is does not do a great job for ugly stuff.
There is this awesome online tool, JSNice, that makes a great job of finding names to obfuscated variables.
We make even obfuscated JavaScript code readable. We will rename variables and parameters to names that we learn from thousands of open source projects. Furthermore, often we are also able to guess or infer type annotations.
