ProtoString is a project that aims to expand upon the methods available in the native String object of JavaScript, by creating a library of methods that you can use as a whole or in snippets. By default, the methods provided are an extenstion of String.prototype, they can however, be easily modified to be functional if preferred. For more information, please check out the ProtoString Wiki as it contains a bunch of information and documentation on this project.
