I’ve just updated the JSWorld library to the latest world locale data derived from Unicode‘s CLDR 1.7.2 (released December 2009). The current JSWorld version is now 1.4.
You can purchase a license and download JSWorld 1.4 from here.
A newer JSWorld version is already planned and work should soon begin on it if all goes well. It will add methods to parse formatted currency amounts, numeric amounts and data/time strings.
Finally, huge thanks to the many people who contribute to the Unicode’s ongoing CLDR process of keeping an up-to-date database of the world’s various locales!
