JavaScript culture sensitive currency formatting

How can i format currency related data in a manner that is culture aware in JavaScript?

From stackoverflow iulianchira

• Dojo has a currency formatter that's locale aware.

  If you don't want to include Dojo in your project just for this function, then perhaps you can localize the currency in your back-end?

  georgebrock : I believe the Dojo currecy formatting is based on XML data from the Unicode Common Locale Data Repository (http://unicode.org/cldr). While Dojo will do the hard work for you, if you don't want to use it you can get the raw data from there.
