iLib is an internationalization library for JavaScript that was created because with the advent of AJAX, it is no longer possible to avoid internationalization. Previously, you could format dates in the user's locale on the server. Now, Web services called via AJAX return time stamps in Unix time and formatting has to be done in the browser, but the standard library is inadequate. In addition to dates, the library handles times, numbers, currency, percentages, calendar calculations (Arabic, Hebrew, Gregorian, and Julian), time zones, string translation, string formatting and choice formats, locale info, ctype functions, and Unicode normalization.
