dispatch table pattern to obtain the localized date printer for one person Note that the returned function expect the date in its closure scope "this.date" It use date_format.js lib to augmenting Date function with format method. Obtained from http://jsfiddle.net/phZr7/1/

i18n.js

/* functions printers outside for better reuse*/
var date_printer={
        //US = United States, UK = United Kingdom, AU = Australia
    US: function(){return "US: "+this.date.format("mm/dd/yy");},
    UK: function(){return "UK: "+this.date.format("dd/mm/yy");},
    AU: function(){return "AU: "+this.date.format("dd/mm/yy");}
};

test.js

var context={date:"1976-06-13"};
var us_printer=date_printer.US;
us_printer.call(context); // return US: 06/13/76

var au_printer=date_printer.AU;
au_printer.call(context); // return AU: 13/06/76
