Some implementations are merely using several regular-expressions to trim whitespace and comments (even though regex for parsing HTML/XML is ill-advised, for a good read see [Regular Expressions: Now You Have Two Problems](http://blog.codinghorror.com/regular-expressions-now-you-have-two-problems/)). Some implementations are much more profound, such as the [YUI Compressor](http://yui.github.io/yuicompressor/) and [Google Closure Compiler](https://github.com/google/closure-compiler) for JS. As most existing implementations either use Java or JavaScript and don't focus on performance, they are pretty slow. Additionally, loading the whole file into memory at once is bad for really large files (or impossible for streams). +Minifiers or bindings to minifiers exist in almost all programming languages.

It removes comments, whitespace and line breaks whenever it can. It employs all the rules that [JSMin](http://www.crockford.com/javascript/jsmin.html) does too, but has additional improvements.
