Java’s String.format() in JavaScript

For a recent project I needed to use Java’s excellent String.format() in JavaScript. I couldn’t find a implementation that did this, so I decided to try and port it from the OpenJDK sources. In case you are interested, please see my github project:

Currently, all formatting flags are supported. Conversion from integer, long, double and all kinds of dates are implemented. Not implemented is conversion to scientific format, hexadecimal and some other stuff, although it is quite straight-forward to implement the latter.
